Description

Secure communication method using planet and entity terminal using the same

[0001] The present invention relates to a method for secure communication between entity terminals, and more particularly, to a method for performing secure communication between entity terminals using a virtual planet, and an entity terminal using the same.

[0002] Recently, in the field of Internet-based communication technology, new communication technologies such as voice communication, cloud / grid computing, person-to-person (P2P), and machine-to-machine (M2M) have emerged, and these new communication technologies have been developed with a focus not only on data transmission speed but also on the security of communication channels formed between terminals.

[0003] Typically, data transmitted through communication channels is encrypted for security purposes, making it difficult to convert back to the original data even if it is leaked to an unspecified party. This data encryption method involves redistributing the original data using an algorithm that utilizes a designated function or appending a predetermined permutation to the original data. Representative methods include block encryption methods such as DES (Data Encryption Standard), FEAL (Fast Data Encipherment Algorithm), and AES (Advanced Encryption Standard), as well as pseudorandom number add-type cryptography.

[0004] Furthermore, since these encryption algorithms utilize security keys to encrypt and decrypt original data, terminals connected via a communication channel must share these keys. One example is a method that utilizes public key infrastructure (PKI).

[0005] However, the conventional method simply exchanges security keys, so whenever communication is hacked, fixed key values ​​and data are exposed, and since the key exchange method is fixed in the client's internal code, there is a fundamental limitation that it will inevitably be hacked at some point if the time condition is infinite.

[0006] Additionally, the conventional method has the disadvantage of being complicated in the process of sharing security keys.

[0007] Therefore, the present applicant proposes a method that simplifies the process of sharing a security key and fundamentally prevents hacking.

[0008] The purpose of the present invention is to solve all of the problems of the above-mentioned prior art.

[0009] In addition, another object of the present invention is to provide a secure communication method that simplifies the process of sharing a security key by using location information of a planet rotating in real time after a predetermined time as a security key.

[0010] In addition, another object of the present invention is to provide a secure communication method that can fundamentally block hacking regardless of time conditions by using a security key corresponding to a key value that changes in real time according to position information of a planet rotating in real time after a predetermined time.

[0011] A representative configuration of the present invention to achieve the above purpose is as follows.

[0044] FIG. 1 schematically illustrates an entity terminal performing secure communication using a planet according to one embodiment of the present invention. Referring to FIG. 1, an entity terminal (100) may include a memory (101) storing instructions for performing secure communication using a planet, and a processor (102) performing secure communication using a planet according to the instructions stored in the memory (101).

[0045] Specifically, the entity terminal (100) may typically achieve desired system performance using a combination of computing devices (e.g., devices that may include computer processors, memory, storage, input devices and output devices, and other components of conventional computing devices; electronic communication devices such as routers, switches, etc.; electronic information storage systems such as network attached storage (NAS) and storage area networks (SAN)) and computer software (i.e., instructions that cause the computing device to function in a particular manner) but is not limited thereto.

[0046] Additionally, the processor of the computing device may include hardware components such as a Micro Processing Unit (MPU) or a Central Processing Unit (CPU), cache memory, and a data bus. Furthermore, the computing device may further include software components such as an operating system and applications that perform specific purposes.

[0047] However, this does not exclude the case where the computing device includes an integrated processor in which the medium, processor, and memory for implementing the present invention are integrated.

[0048] Meanwhile, the processor (102) of the entity terminal (100) may, when a communication connection request is obtained from another entity terminal according to instructions stored in the memory (101), change the initial rotation axis to a first current rotation axis that is randomly selected at the first current time when the communication connection request is obtained by referring to the first planet stored in the entity terminal, rotate according to first current rotation condition information that is randomly selected based on the first current rotation axis, generate and store a first planet token having a first planet token address generated by referring to first current position information including at least one of a first current longitude, a first current latitude, and a first current azimuth angle of a specific point corresponding to the first current rotation axis at the first current time, and transmit the first planet token address, the first current time, the first current position information, and the first current rotation condition information to the other entity terminal. At this time, the first planet is generated using a specific point randomly selected in the spatial coordinate system, and rotates according to initial rotation condition information randomly selected based on the initial rotation axis randomly selected, and the first planet address generated with reference to the initial position information including at least one of the initial longitude, initial latitude, and initial azimuth angle of the specific point corresponding to the initial rotation axis at the initial time can be set.And, the processor (102) of the entity terminal (100) obtains first predicted state information, which predicts the state in which the first planet token rotates according to the first current rotation condition information during the elapsed time from the first current time to the second current time, by referring to the first current time, the first current position information, and the first current rotation condition information, from another entity terminal at a second current time when accessing the first planet token using the first planet token address, and compares the first reference state information corresponding to the state of the first planet token at the second current time with the first predicted state information, and if the first reference state information and the first predicted state information match, performs a process of creating a secure communication channel between the entity terminal and the other entity terminal using the first planet token.

[0049] In addition, the processor (102) of the entity terminal (100) may, when a communication connection request is obtained from another entity terminal according to instructions stored in the memory (101), change the initial rotation axis to a first current rotation axis that is randomly selected at the first current time when the communication connection request is obtained by referring to the first planet stored in the entity terminal, rotate according to first current rotation condition information that is randomly selected based on the first current rotation axis, generate and store a first planet token having a 1_1 planet token address generated by referring to the 1_1 current position information that includes at least one of the 1_1 current longitude, the 1_1 current latitude, and the 1_1 current azimuth angle of a specific point corresponding to the first current rotation axis at the first current time, and transmit the first planet token address, the 1_1 current time, the 1_1 current position information, and the 1_1 current rotation condition information to the other entity terminal. And, the processor (102) of the entity terminal (100) obtains 1_1 predicted state information, which predicts the state in which the first planet token rotates according to the 1_1 current rotation condition information during the elapsed time from the 1_1 current time to the 2_1 current time, by referring to the 1_1 current time, the 1_1 current position information, and the 1_1 current rotation condition information, from the other entity terminal at the 2_1 current time when accessing the first planet token using the 1_1 planet token address, and compares the 1_1 reference state information corresponding to the state of the first planet token at the 2_1 current time with the 1_1 predicted state information, and if the 1_1 reference state information and the 1_1 predicted state information match, a process of requesting a communication connection to the other entity terminal can be performed.Thereafter, when the processor (102) of the entity terminal (100) obtains the 1_2 planet token address, the 1_2 current time, the 1_2 current position information, and the 1_2 current rotation condition information corresponding to the second planet token from another entity terminal, at the 2_2 current time, the 1_2 current time, the 1_2 current position information, and the 1_2 current rotation condition information, the processor (102) generates the 1_2 predicted state information that predicts the state in which the second planet token rotates according to the 1_2 current rotation condition information during the elapsed time from the 1_2 current time to the 2_2 current time, and transmits the 1_2 predicted state information to the other entity terminal using the 1_2 planet token address, so that the other entity terminal compares the 1_2 reference state information corresponding to the state of the second planet token at the 2_2 current time with the 1_2 predicted state information to confirm whether the 1_2 reference state information and the 1_2 predicted state information match, and If it is confirmed that the 1_2 reference state information and the 1_2 predicted state information match at the entity terminal, a process of creating a secure communication channel between the entity terminal and another entity terminal using the 1st planet token and the 2nd planet token can be performed.

[0050] A method for secure communication using a planet through an entity terminal according to one embodiment of the present invention configured as described above will be described with reference to FIG. 2. In the following description, an entity terminal that creates secure communication is referred to as a first entity terminal, and another entity terminal that performs communication with the entity terminal is referred to as a second entity terminal.

[0051] First, a first user using a first entity terminal (100) can create a first planet that rotates according to initial rotation condition information on the first entity terminal (100) (S10). At this time, the first planet is a virtual planet created by a planet service app and operated on the first entity terminal (100). A state of rotating in real time according to the initial rotation condition information may be displayed on the display of the first entity terminal (100), or may be operated in the background.

[0052] For example, referring to FIG. 3, the planet service app installed in the first entity terminal (100) can create a virtual planet using a specific point (p) randomly selected in a spatial coordinate system (xyz coordinate system or spherical coordinate system) in response to a planet creation request signal. At this time, when the planet service app randomly creates a specific point (p), the specific point (p) can be selected so that the distance from the center of the spatial coordinate system to the specific point (p), i.e., the radius of the virtual planet, has a preset radius. In addition, in contrast, when the first planet is used as a storage for data storage, the specific point (p) can be randomly selected so as to correspond to a specific radius corresponding to a storage capacity set by the first user.

[0053] And, the planet service app in the first entity terminal (100) can randomly select the initial rotation axis (11) of the virtual planet.

[0054] Accordingly, a specific point (p) may have initial position information including at least one of an initial longitude, an initial latitude, and an initial azimuth angle corresponding to the initial rotation axis (11).

[0055] In addition, the planet service app in the first entity terminal (100) can randomly select the initial rotation condition information of the virtual planet, and can generate the first planet (10) that rotates in real time according to the initial rotation condition information by rotating the virtual planet based on the initial rotation axis according to the initial rotation condition information.

[0056] At this time, the initial rotation condition information may include at least a portion of the first rotation condition information related to the horizontal direction, which is the direction in which the virtual planet rotates around the initial rotation axis (11), and the second rotation condition information related to the vertical direction, which is the direction orthogonal to the horizontal direction. Here, the horizontal direction may mean a direction corresponding to a trajectory that rotates around the rotation axis.

[0057] For example, the first rotation condition information and the second rotation condition information may be set to a condition of rotating 3 degrees in the horizontal direction and 5 degrees in the vertical direction for 1 second, but the present invention is not limited thereto, and the virtual planet may be rotated in various ways by arbitrarily setting the first rotation condition information and the second rotation condition information. Here, the condition of rotating 3 degrees in the horizontal direction and 5 degrees in the vertical direction for 1 second may mean a concept of rotating discontinuously at 1-second intervals or a concept of rotating continuously.

[0058] In addition, a first planet address may be set for the first planet (10) by referring to initial position information including the initial time at which the first planet (10) was created and at least one of the initial longitude, initial latitude, and initial azimuth angle of a specific point (p) corresponding to the initial rotation axis at the initial time.

[0059] At this time, the first planet address can be generated by hashing the initial time and initial location information, but the present invention is not limited thereto, and can be generated by various methods that generate a single unique value using the initial time and initial location information.

[0060] For example, if the initial time at which the first planet was created is “1696320000” and the initial latitude, initial longitude, and initial azimuth angle of a specific point (p) are “126.9784 degrees”, “37.5667 degrees”, and “82.8568 degrees”, respectively, the first planet address can be expressed as follows.

[0061] 1st planet address = hash(1696320000 + 126.9784 degrees + 37.5667 degrees + 82.8568 degrees)

[0062] At this time, the initial time “1696320000” is the Unix time corresponding to “October 3, 2023 17:00:00 UTC+0900 / Korea Standard Time”, and the Unix time can be expressed as an integer by converting the elapsed time from January 1, 1970 00:00:00 Coordinated Universal Time (UTC) into seconds.

[0063] Accordingly, a first planet (10) having a first planet address, which is unique identification information, and rotating in real time according to initial rotation condition information can be created in the first entity terminal (100).

[0064] At this time, the first entity terminal (100) can set the active time of the first planet (10), and can cause the first planet (10) to disappear when the set active time elapses.

[0065] And, the first entity terminal (100) can store at least some of the initial time, initial rotation axis information, and initial position information related to the creation of the first planet (10). For example, the first entity terminal (100) can store information related to the creation of the first planet (10) in a SE (Secure Element).

[0066] Meanwhile, the above description describes the creation of the first planet (10) in the first entity terminal (100), but by the same method, each user using the planet service can create planets in each entity terminal that have respective planet addresses and rotate in real time according to respective rotation condition information.

[0067] Again, referring to FIG. 2, when a communication connection request is obtained from a second entity terminal, the first entity terminal (100) can generate (S20) a first planet token that rotates according to the first current rotation condition information using the first planet.

[0068] For example, referring to FIG. 4, in a state where the first planet (10) rotates in real time based on the initial rotation condition information about the initial rotation axis (11), in a state where the attitude of the first planet (10) is acquired at the first current time when a communication connection request is acquired as in (a) of FIG. 4, the initial rotation axis (11) can be changed to a first current rotation axis (21) that is randomly determined as in (b) of FIG. 4, thereby generating a first planet token (20).

[0069] Then, a specific point (p) may have first current position information including at least one of a first current longitude, a first current latitude, and a first current azimuth angle corresponding to a first current rotation axis (21).

[0070] In addition, the first entity terminal (100) can randomly select the first current rotation condition information of the first planet token (20), and can cause the first planet token (20) to rotate based on the first current rotation axis (21) according to the first current rotation condition information.

[0071] At this time, the first current rotation condition information may include at least a part of the first rotation condition information related to the horizontal direction, which is the direction in which the first planet token (20) rotates around the first current rotation axis (21), and the second rotation condition information related to the vertical direction, which is the direction orthogonal to the horizontal direction.

[0072] For example, the first rotation condition information and the second rotation condition information may be set to conditions for rotating 10 degrees in the horizontal direction and 20 degrees in the vertical direction for 1 second, but the present invention is not limited thereto, and the first planet token (20) may be rotated in various ways by arbitrarily setting the first rotation condition information and the second rotation condition information.

[0073] In addition, the first planet token (20) may be set with a first planet token address generated by referring to first current position information including at least one of a first current longitude, a first current latitude, and a first current azimuth angle of a specific point (p) corresponding to the first current rotation axis at the first current time, and a first current time when the first planet token (20) is generated.

[0074] At this time, the first planet token address can be generated by hashing the first current time and the first current location information. However, the present invention is not limited thereto, and the first current time and the first current location information can be generated using various methods that generate a single unique value. In addition, the first current time may be Unix time, but the present invention is not limited thereto, and may be a standard time commonly used by all entity terminals using the planet service.

[0075] Accordingly, the first entity terminal (100) has a first planet token address, which is unique identification information, and a first planet token (20) that rotates in real time according to the first current rotation condition information can be generated.

[0076] At this time, the first entity terminal (100) can set the active time of the first planet token (20), and can cause the first planet token (20) to be extinguished when the set active time elapses.

[0077] And, the first entity terminal (100) can store at least some of the first current time, the first current rotation axis information, and the first current location information related to the generation of the first planet token (20). For example, the first entity terminal (100) can store information related to the generation of the first planet token (20) in a SE (Secure Element).

[0078] Again, referring to FIG. 2, the first entity terminal (100) can transmit (S30) to the second entity terminal the first planet token address corresponding to the first planet token generated at the first current time, the first current time, the first current location information, and the first current rotation condition information.

[0079] Then, the second entity terminal can obtain first predicted state information that predicts the state in which the first planet token rotates according to the first current rotation condition information during the elapsed time from the first current time to the second current time by referring to the first current time, the first current position information, and the first current rotation condition information obtained from the first entity terminal (100) at the second current time when accessing the first planet token using the first planet token address. At this time, the first predicted state information is used as a security key for secure communication, and may have the position information of the first planet token, which changes in real time, as a key value. In addition, the second current time may be Unix time, but the present invention is not limited thereto, and may be a standard time commonly used by all entity terminals using the planet service.

[0080] For example, the second entity terminal may generate the first predicted state information to include a predicted second hash value obtained by hashing predicted second current location information including at least one of a predicted second current longitude, a predicted second current latitude, and a predicted second current azimuth angle corresponding to a specific point in the first planet token rotated from the first current time to the second current time in response to the second current rotation condition information.

[0081] And, the second entity terminal can transmit the first predicted status information to the first entity terminal (100) using the first planet address.

[0082] Thereafter, when first predicted state information predicting the state of the first planet token at the second current time is obtained from the second entity terminal, the first entity terminal (100) can compare the first reference state information corresponding to the state of the first planet token at the second current time with the first predicted state information (S40).

[0083] For example, the first entity terminal (100) may generate a reference second hash value by performing a hash operation on reference second current location information including at least one of a second current longitude, a second current latitude, and a second current azimuth angle corresponding to a specific point in the first planet token at the second current time, and the second current longitude, and may compare the second reference hash value with a predicted second hash value obtained from the second entity terminal.

[0084] And, if the first reference state information and the first predicted state information match, the first entity terminal (100) can create a secure communication channel between the first entity terminal and the second entity terminal using the first planet token (S50).

[0085] At this time, the first entity terminal (100) can create a secure communication channel with the second entity terminal via a peer-to-peer network. However, the present invention is not limited to this and can be applied to various communication methods for creating a secure communication channel.

[0086] Meanwhile, if the first planet token is deleted or destroyed before the active time has elapsed while the active time is set for the first planet token (e.g., if the first entity terminal is turned off), the first entity terminal (100) can regenerate the first planet token using the first planet.

[0087] That is, if the first planet token is deleted before the active time elapses, the first entity terminal can generate a first planet token corresponding to the first current time, the first current location information, and the first current rotation condition information from the first planet at the third current time, and then regenerate and store the first planet token by rotating the first planet token according to the first current rotation condition information during the elapsed time from the first current time to the third current time.

[0088] For example, at a third current time when the first planet token is to be regenerated, the first entity terminal (100) generates the first planet token by changing the initial rotation axis of the first planet to the first current rotation axis set at the time of generation of the first planet token, while the first planet is located at the first current time when the first planet token is generated, and rotates the first planet token based on the first current rotation axis during the elapsed time from the first current time to the third current time according to the first current rotation condition information set at the time of generation of the first planet token so that the first planet token is synchronized to the third current time, and then causes the first planet token synchronized to the third current time to rotate based on the first current rotation axis according to the first current rotation condition information, thereby regenerating the first planet token.

[0089] In addition, when the request for validation of the first planet token is obtained at the fourth current time, the first entity terminal (100) can generate a reference first planet token corresponding to the first current time, the first current location information, and the first current rotation condition information from the first planet, and then check whether the reference first planet token, which is rotated according to the first current rotation condition information during the elapsed time from the first current time to the fourth current time, matches the first planet token stored at the fourth current time, thereby verifying the validity of the first planet token. That is, the entity terminal (100) can verify the validity of the first planet token by verifying whether the location information of the reference first planet token corresponding to the fourth current time matches the location information of the first planet token.

[0090] In contrast, when the request for validation of the first planet token is obtained at the fourth current time, the first entity terminal (100) may generate a reference first planet token corresponding to the first current time, the first current position information, and the first current rotation condition information from the first planet, and may verify the validity of the first planet token by checking whether the position information of the first planet token that has been rotated backwards to the first current time according to the first current rotation condition information matches the position information of the reference first planet token at the fourth current time.

[0091] According to this method, the present invention can simplify the process of sharing a security key by using the position information of a planet rotating in real time after a predetermined time as a security key, and provide a secure communication channel between entity terminals that fundamentally blocks hacking.

[0092] Meanwhile, in the above, the first entity terminal (100) generated the first planet token in response to a communication connection request from the second entity terminal. However, in contrast, the first entity terminal (100) may generate a secure communication channel in response to a communication connection request from the second entity terminal while generating the first planet token.

[0093] That is, when a communication connection request is obtained from a second entity terminal while the first entity terminal (100) is generating and storing a first planet token at a first current time, information related to the generation of the first planet token at the first current time is transmitted to the second entity terminal, and when first predicted state information corresponding to the first planet token at the second current time is obtained using the information related to the generation of the first planet token from the second entity terminal, a secure communication channel between the first entity terminal and the second entity terminal can be generated using the first planet token by confirming whether the first reference state information and the first predicted state information match.

[0094] In addition, in the above, the first entity terminal (100) created a secure communication channel with one second entity terminal using the first planet token, but, unlike this, the first planet token may be used to create secure communication channels with multiple other entity terminals.

[0095] For example, when a first entity terminal (100) wants to share data with a plurality of approved other entity terminals, the first entity terminal (100) generates a first planet token at a first current time, and then transmits information related to the generation of the first planet token at the first current time to the approved other entity terminals, and when first predicted state information corresponding to the first planet token at the second current time is acquired using the information related to the generation of the first planet token from each of the approved other entity terminals, it is checked whether each of the first predicted state information matches the first reference state information, and only the other entity terminals that are confirmed to match can access the data. At this time, if the specific first predicted state information is hacked by a third party, the third party may attempt to access the data using the hacked first predicted state information, but the location information, which is the key value of the first planet token at the specific time at which the third party attempts to access the data using the hacked first predicted state information, is different from the location information of the first planet token at the second current time corresponding to the hacked first predicted state information, and accordingly, the third party cannot access the data using the hacked first predicted state information.

[0096] Meanwhile, in the above, a secure communication channel between the first entity terminal and the second entity terminal is created using the first planet token generated at the first entity terminal. However, unlike this, a secure communication channel between the first entity terminal and the second entity terminal may be created using both the first planet token generated at the first entity terminal and the second planet token generated at the second entity terminal, which will be briefly described as follows. In the description below, a detailed description will be omitted for parts that can be easily understood from the description with reference to FIG. 2.

[0097] First, when a communication connection request is obtained from a second entity terminal, the first entity terminal (100) changes the initial rotation axis to a first current rotation axis that is randomly selected at the first current time when the communication connection request is obtained with reference to the first planet, rotates according to first current rotation condition information that is randomly selected based on the first current rotation axis, generates and stores a first planet token having a 1_1 planet token address generated with reference to the 1_1 current position information that includes at least one of the 1_1 current longitude, the 1_1 current latitude, and the 1_1 current azimuth angle of a specific point corresponding to the first current rotation axis at the first current time, and transmits the first planet token address, the 1_1 current time, the 1_1 current position information, and the 1_1 current rotation condition information to the second entity terminal.

[0098] And, the first entity terminal (100) can obtain the 1_1 predicted state information, which predicts the state in which the first planet token rotates according to the 1_1 current rotation condition information during the elapsed time from the 1_1 current time to the 2_1 current time, by referring to the 1_1 current time, the 1_1 current position information, and the 1_1 current rotation condition information at the 2_1 current time when accessing the 1st planet token using the 1_1 planet token address from the 2_1 entity terminal.

[0099] Thereafter, the first entity terminal (100) compares the 1_1 reference state information corresponding to the state of the first planet token at the 2_1 current time with the 1_1 predicted state information, and if the 1_1 reference state information and the 1_1 predicted state information match, a communication connection can be requested to the 2nd entity terminal.

[0100] And, when the 1_2 planet token address corresponding to the 2nd planet token, the 1_2 current time, the 1_2 current position information, and the 1_2 current rotation condition information are acquired from the 2nd entity terminal, the 1st entity terminal (100) may, at the 2_2 current time, refer to the 1_2 current time, the 1_2 current position information, and the 1_2 current rotation condition information, generate 1_2 predicted state information that predicts the state in which the 2nd planet token rotates according to the 1_2 current rotation condition information during the elapsed time from the 1_2 current time to the 2_2 current time, and then transmit the 1_2 predicted state information to the 2nd entity terminal using the 1_2 planet token address.

[0101] Then, the second entity terminal can compare the 1_2 reference state information corresponding to the state of the second planet token at the 2_2 current time with the 1_2 predicted state information to check whether the 1_2 reference state information and the 1_2 predicted state information match.

[0102] Thereafter, if it is confirmed that the 1_2 reference state information and the 1_2 predicted state information match in the second entity terminal, the first entity terminal (100) can create a secure communication channel between the first entity terminal and the second entity terminal using the first planet token and the second planet token.
