Description

Technical Field

[0001] This invention relates to the field of data transmission control, and more specifically to an encrypted ribbon cable with dynamically set counting limits. Background Technology

[0002] Ribbon cables are widely used for data transmission in moving parts and moving areas, such as data cables connecting hard drives and optical drives to motherboards in computers, data cables connecting displays to motherboards in mobile phones, and data cables connecting devices. Ribbon cables offer high assembly reliability and quality, reducing the amount of hardware required for internal connections, such as solder joints, relays, baseboard circuitry, and cables commonly used in traditional electronic packaging. Using ribbon cables provides higher assembly reliability and quality.

[0003] However, due to the flexible and thin nature of ribbon cables, their lifespan is relatively limited. Furthermore, existing ribbon cables lack a counting function, leading to cable damage after excessive use and affecting data transmission. Secondly, existing ribbon cables lack encryption capabilities, failing to prevent reverse engineering and compromising copyright protection.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an encrypted ribbon cable with dynamically set counting limits, which addresses the above-mentioned defects of the prior art. This invention aims to solve the problems of existing ribbon cables not having a counting function, which can lead to cable damage when used too many times, thus affecting data transmission, and the lack of encryption function, which makes it impossible to prevent copying and is detrimental to copyright protection.

[0006] The technical solution adopted by this invention to solve the technical problem is as follows:

[0007] This invention provides an encrypted ribbon cable with dynamically set counting limits, wherein the encrypted ribbon cable includes:

[0008] An encryption verification module, a hardware ID interface and a control module coupled to the encryption verification module; wherein, the control module includes a counting unit, a setting unit and a limiting unit, the encryption verification module includes an encryption verification unit and a storage unit, the encryption verification unit is provided with an encryption IC, the storage unit is provided with an EEPROM memory, and the EEPROM memory is partitioned to store data parameters.

[0009] In one implementation, the data parameters include:

[0010] The first ribbon cable ID, the number of times it has been used, and the limit number of times it can be used; wherein, the first ribbon cable ID is a number of pre-stored valid ribbon cable IDs; the number of times it has been used corresponds one-to-one with the first ribbon cable ID and is used to record the number of times the encrypted ribbon cable has been used; the limit number of times it can be used corresponds one-to-one with the first ribbon cable ID and is used to limit the upper limit of the number of times the encrypted ribbon cable can be used.

[0011] In one implementation, the hardware ID interface is used to read the ID of the encrypted ribbon cable and send the ID of the encrypted ribbon cable as a second ribbon cable ID to the encryption verification unit.

[0012] In one implementation, the encryption verification unit is used for:

[0013] Receive the second ribbon cable ID and read the first ribbon cable ID from the EEPROM memory;

[0014] The second ribbon cable ID is compared with the first ribbon cable ID. If the second ribbon cable ID is the same as the first ribbon cable ID, the encrypted ribbon cable is set to an available state. If the second ribbon cable ID is different from the first ribbon cable ID, the encrypted ribbon cable is set to an unavailable state.

[0015] When the encrypted cable is in an available state, the data information transmitted in the encrypted cable is encrypted using an encryption algorithm; wherein, the encryption algorithm includes MD5, SHA1, SHA256, DES, 3DES, AES, RSA and ECC.

[0016] In one implementation, the counting unit is used to calculate the number of times the encrypted cable is used and send the number of times it is used to the setting unit.

[0019] In one implementation, controlling the usage permissions of the encrypted ribbon cable based on the second ribbon cable ID includes:

[0020] The second ribbon cable ID is matched with the first ribbon cable ID in the data parameters. The number of times the first ribbon cable ID has been used and the number of times the limit has been set are compared to obtain the comparison result.

[0021] Based on the comparison results, the usage permissions of the encrypted cable are controlled.

[0022] In one implementation, controlling the usage rights of the encrypted cable based on the comparison result includes:

[0023] If the comparison result shows that the number of times it has been used is less than the limit number of times, then the usage permission of the encrypted cable corresponding to the second cable ID is set to allow use;

[0024] If the comparison result shows that the number of times it has been used is greater than or equal to the limit number of times, then the usage permission of the encrypted cable corresponding to the second cable ID is set to not be allowed.

[0025] In one implementation, when the usage permission is set to disallowed, the encrypted cable cannot transmit encrypted data.

[0038] Currently, ribbon cables are widely used for connections between mobile phone motherboards and testing equipment, as well as between other hardware devices. However, due to their flexible and thin nature, ribbon cables have a relatively limited lifespan. Furthermore, existing ribbon cables lack a counting function, leading to cable damage after excessive use and affecting data transmission. Secondly, existing ribbon cables lack encryption capabilities, failing to prevent reverse engineering and compromising copyright protection.

[0039] Therefore, to solve the above problems, this embodiment provides an encrypted ribbon cable with dynamically set counting limits. This embodiment allows for setting different usage counts for different types of ribbon cables, and the usage count is obtained through a counting unit, enabling real-time monitoring of the ribbon cable's lifespan and wear. Data security is protected through encryption of data transmission. Specifically, the encrypted ribbon cable in this embodiment includes: an encryption verification module, a hardware ID interface coupled to the encryption verification module, and a control module. The control module includes a counting unit, a setting unit, and a limiting unit. The counting unit records the usage count of the ribbon cable for easy after-sales maintenance, while the limiting unit limits the number of uses to ensure the stability of the ribbon cable's quality. The encryption verification module includes an encryption verification unit and a storage unit. The encryption verification unit is equipped with an encryption IC, and the storage unit is equipped with an EEPROM memory. The EEPROM memory stores data parameters in partitions. The encryption verification module enables encrypted communication and verification between the two ends of the ribbon cable to prevent reverse engineering.

[0040] This embodiment provides an encrypted ribbon cable with dynamically set counting limits. For example... Figure 1 As shown, the encrypted cable with dynamically set count limits includes the following structure:

[0041] An encryption verification module, a hardware ID interface and a control module coupled to the encryption verification module; wherein, the control module includes a counting unit, a setting unit and a limiting unit, the encryption verification module includes an encryption verification unit and a storage unit, the encryption verification unit is provided with an encryption IC, the storage unit is provided with an EEPROM memory, and the EEPROM memory is partitioned to store data parameters.

[0042] Specifically, such as Figure 1 As shown, the encryption verification module is coupled to the hardware ID interface, which is used to read the hardware ID of the ribbon cable. The encryption verification module is also coupled to the control module. The encryption verification module is equipped with an encryption IC used to verify the legitimacy of the ribbon cable and encrypt the data transmitted by the ribbon cable. A typical circuit of the encryption IC is shown below. Figure 2 As shown. The encryption IC contains a secure, encrypted EEPROM. Read and write operations can be performed on the EEPROM memory using read / write commands with encryption verification. The EEPROM storage space is divided into several byte-defined functional areas to store different data parameters. The control module includes a counting unit, a setting unit, and a limiting unit. The encryption process is as follows... Figure 3As shown, the 4-byte plaintext input from the host and the 4-byte random number from the TRNG are processed and used as input to the RC4 encryption engine. The RC4 encryption engine uses a 16-byte key from the EEPROM to encrypt the input data and outputs a MAC value. The initialization and authentication process of the EEPROM memory is as follows: Figure 4 As shown. The host authentication process is as follows. Figure 5 As shown, the slave device's authentication write process is as follows: Figure 6 As shown, the slave authentication and reading process is as follows: Figure 7 As shown.

[0043] In one implementation, the data parameters include:

[0044] The first ribbon cable ID, the number of times it has been used, and the limit number of times it can be used; wherein, the first ribbon cable ID is a number of pre-stored valid ribbon cable IDs; the number of times it has been used corresponds one-to-one with the first ribbon cable ID and is used to record the number of times the encrypted ribbon cable has been used; the limit number of times it can be used corresponds one-to-one with the first ribbon cable ID and is used to limit the upper limit of the number of times the encrypted ribbon cable can be used.

[0045] Specifically, the storage space of the EEPROM memory is divided into a set of related storage bytes, and data parameters are set in them, as shown in Table 1.

[0046] Table 1. Placeholder Table for Data Parameters

[0047] 2 Byte 2 Byte 2 Byte 2 Byte 2 Byte

[0048] In the data parameters, the first ribbon cable ID is 2 bytes. During the testing phase after the ribbon cable is produced, the value of the first ribbon cable ID is used. If the first ribbon cable ID is 0x00, it indicates a new ribbon cable. After the first ribbon cable ID is written to the EEPROM memory through the setting module, the first ribbon cable ID and the second ribbon cable ID can be compared to determine whether the ribbon cable is a valid ribbon cable.

[0049] The number of times the cable has been used occupies 2 bytes and is used to count the number of times the cable has been used.

[0050] The inverted count occupies 2 bytes and is used to confirm the correctness of the count and prevent statistical errors caused by EEPROM damage.

[0051] The limit on the number of times a ribbon cable can be used is 2 bytes. This limit is used to restrict the number of times a ribbon cable can be used. Since the number of times a ribbon cable can be used varies depending on the connector, the limit on the number of times a ribbon cable can be used can be set to restrict the number of times different ribbon cables can be used, so as to conform to the lifespan of different ribbon cable models.

[0052] The limit count inverted occupies 2 bytes and is used to ensure the reliability of the limit.

[0053] Among them, the number of times used, the inverted number of times used, the limit number of times, and the inverted number of times limit correspond one-to-one with the first ribbon cable ID. That is, each first ribbon cable ID is set with its own number of times used, the inverted number of times used, the limit number of times, and the inverted number of times limit, so as to achieve independent restrictions on different ribbon cables.

[0054] In one implementation, the hardware ID interface is used to read the ID of the encrypted ribbon cable and send the ID of the encrypted ribbon cable as a second ribbon cable ID to the encryption verification unit.

[0055] Specifically, a hardware ID interface is provided on the encrypted ribbon cable. The ID of the encrypted ribbon cable can be read through this interface. The encrypted ribbon cable has 8-10 pins. By connecting the pins high (3.3V power supply or logic high) or low (ground), the CPU reads the pin high / low signal and converts it into a 10-bit binary encrypted ribbon cable ID, i.e., the hardware ID. After reading the encrypted ribbon cable ID, the hardware ID interface sends this ID as the second ribbon cable ID to the encryption verification unit.

[0056] For example, a 10-bit ID pin can theoretically support 1023 encrypted ribbon cable IDs. The number of encrypted ribbon cable IDs can be increased by adding more encrypted ribbon cable ID pins. As shown in Table 2, when bits 9-0 are 000000011, the encrypted ribbon cable ID is 0x003; when bits 9-0 are all 1, the encrypted ribbon cable ID is 0x3FF.

[0057] Table 2. Hardware ID Examples

[0058] 0 0 0 0 0 0 0 0 1 0x001 0 0 0 0 0 0 0 1 0 0x002 0 0 0 0 0 0 0 1 1 0x003 0 0 0 0 0 0 1 0 0 0x004 … … … … … … … … … … 1 1 1 1 1 1 1 1 1 0x3FF

[0059] Using the hardware ID interface has the following effects:

[0060] Facilitates the initialization of encrypted ribbon cables: Before production, the encryption IC can be a unified chip. After the encrypted ribbon cables are manufactured, a corresponding hardware ID, i.e., the second ribbon cable ID, can be set for each ribbon cable. During ribbon cable testing, the second ribbon cable ID can be read through the ribbon cable's hardware ID interface, and the corresponding initialization data can be written according to the second ribbon cable ID.

[0061] To check if the encryption IC on the encryption cable corresponds to the encryption cable: Illegal vendors buy old encryption cables, remove the encryption IC, and stick it on counterfeit encryption cables. To prevent this from happening, the testing equipment will read the second cable ID and compare it with the first cable ID stored in the encryption chip before testing. If they are different, it can be considered an illegal cable.

[0062] In one implementation, the encryption verification unit is used for:

[0063] Receive the second ribbon cable ID and read the first ribbon cable ID from the EEPROM memory;

[0064] The second ribbon cable ID is compared with the first ribbon cable ID. If the second ribbon cable ID is the same as the first ribbon cable ID, the encrypted ribbon cable is set to an available state. If the second ribbon cable ID is different from the first ribbon cable ID, the encrypted ribbon cable is set to an unavailable state.

[0065] When the encrypted cable is in an available state, the data information transmitted in the encrypted cable is encrypted using an encryption algorithm; wherein, the encryption algorithm includes MD5, SHA1, SHA256, DES, 3DES, AES, RSA and ECC.

[0066] Specifically, upon receiving the second ribbon cable ID, the system searches the parameter data in the EEPROM memory to see if a first ribbon cable ID with the same value is already stored. If so, it indicates that the encrypted ribbon cable corresponding to the second ribbon cable ID is valid, and the encrypted ribbon cable can be set to an available state. If a first ribbon cable ID with the same value is not found in the parameter data, it indicates that the encrypted ribbon cable corresponding to the second ribbon cable ID is invalid, and its second ribbon cable ID has not been pre-stored, so the encrypted ribbon cable can be set to an unavailable state.

[0067] Specifically, when the encryption cable is in an available state, it contains an encryption IC. Read and write operations can be performed on the EEPROM memory using read / write commands with encryption verification. The second cable ID is read through the corresponding interface, and communication with the encryption IC is established to complete encryption verification. When the encryption cable is in an available state, communication is refused.

[0068] For example, when the EEPROM memory has the storage parameters shown in Table 3, if the received second ribbon cable ID is 0x103, the same first ribbon cable ID cannot be found in the data parameter table. Therefore, the encrypted ribbon cable corresponding to the second ribbon cable ID of 0x103 is set to unusable. If the received second ribbon cable ID is 0x001, the same first ribbon cable ID can be found in the data parameter table. Therefore, the encrypted ribbon cable corresponding to the second ribbon cable ID of 0x001 is set to usable, and the data information transmitted in the encrypted ribbon cable is encrypted using an encryption algorithm.

[0069] Table 3. Data Parameter Table

[0070] 0x001 0x001 0x111 0x002 0x010 0x111

[0071] In one implementation, the counting unit is used to calculate the number of times the encrypted cable is used and send the number of times it is used to the setting unit.

[0072] Specifically, during the use of encrypted ribbon cables, the following abnormal situations often occur: the ribbon cable breaks down without warning during use; the ribbon cable works fine for a while but suddenly the assembly burns out; the ribbon cable is fine at first but becomes unusable after a period of use. The main reasons for these problems are: customers have used it many times but think the ribbon cable is new; customers have used the ribbon cable beyond its service life but continue to use it, i.e., overuse causing unstable testing; the ribbon cable has not reached its usage limit or the designed usage limit is unreasonable, and the ribbon cable can actually continue to be used. In this embodiment, the counting unit increments the count every time the encrypted ribbon cable connects to the hardware device, thus enabling the monitoring of the number of times the encrypted ribbon cable has been used, making it easy to know the true number of times the ribbon cable has been used. By sending the usage count to the setting unit, the data parameters are updated by the setting unit. Monitoring the number of times the encrypted ribbon cable has been used can also provide a basis for after-sales service.

[0073] For example, when the counting unit calculates the number of times the encrypted ribbon cable with the second ribbon cable ID 0x001 has been used (0x003 times) by the number of times the encrypted ribbon cable is inserted, it sends the second ribbon cable ID 0x001 and the number of times it has been used (0x003) to the setting unit, notifying the setting unit that the encrypted ribbon cable with the second ribbon cable ID 0x001 has been used 3 times.

[0074] In one implementation, the setting unit is configured to set the number of times used in the data parameters in the EEPROM memory in the storage unit according to the number of times used, and to set the first ribbon cable ID and the limit number of times in the data parameters according to user instructions.

[0075] Specifically, the data parameters stored in the encrypted ribbon cable in this embodiment can be set by the setting unit. When the setting unit receives the usage count sent by the counting unit, it can write the usage count into the EEPROM memory, updating the usage count in the data parameters. If the user instruction includes the first ribbon cable ID and the limit usage data that need to be updated, the setting unit will update the data parameters according to the user instruction.

[0076] For example, when the setting unit receives a message from the counting unit indicating that the usage count of the encrypted ribbon cable with the second ribbon cable ID 0x001 is 0x010, it writes the usage count into the EEPROM memory and updates the corresponding usage count of the encrypted ribbon cable with the first ribbon cable ID 0x001 in the data parameters to 0x010. If the user instruction includes an instruction to update the limit usage count of the first ribbon cable ID 0x002 to 0x030, the setting unit will update the data parameters according to the user instruction to set the limit usage count of the first ribbon cable ID 0x002 to 0x030.

[0077] In one implementation, the restriction unit is used to control the usage rights of the encrypted ribbon cable based on the second ribbon cable ID.

[0078] In one implementation, controlling the usage permissions of the encrypted ribbon cable based on the second ribbon cable ID includes:

[0079] The second ribbon cable ID is matched with the first ribbon cable ID in the data parameters. The number of times the first ribbon cable ID has been used and the number of times the limit has been set are compared to obtain the comparison result.

[0080] Based on the comparison results, the usage permissions of the encrypted cable are controlled.

[0081] Specifically, the restriction unit is used to control the usage permissions of the ribbon cable, which is distinguished by its ribbon cable ID. Once the second ribbon cable ID is obtained, the corresponding first ribbon cable ID, along with the number of uses and the limit set for that first ribbon cable ID, can be obtained by querying the data parameters. Then, the number of uses and the limit need to be compared to determine whether the encrypted ribbon cable has reached its usage limit.

[0082] For example, when the second ribbon cable ID is obtained as 0x002, the restriction unit can query the data parameters to find that when the corresponding first ribbon cable ID is 0x002, the used count and the limit count are set to 0x008 and 0x115 respectively. The used count and the limit count are then compared, and the result shows that the used count is less than the limit count. The usage permissions of the ribbon cable are then controlled based on this comparison result.

[0083] In one implementation, controlling the usage rights of the encrypted cable based on the comparison result includes:

[0084] If the comparison result shows that the number of times it has been used is less than the limit number of times, then the usage permission of the encrypted cable corresponding to the second cable ID is set to allow use;

[0085] If the comparison result shows that the number of times it has been used is greater than or equal to the limit number of times, then the usage permission of the encrypted cable corresponding to the second cable ID is set to not be allowed.

[0086] Specifically, if the number of uses is less than the limit, it means the ribbon cable has not yet reached the usage limit and can continue to be used. If the number of uses is greater than or equal to the limit, it means the ribbon cable has reached the usage limit and will not be allowed to continue to be used. The usage limit is different for each ribbon cable. Some ribbon cable connectors have a higher number of uses, while others have a lower limit. If a single quantity limit is blindly applied, many problems will arise. Therefore, by setting the usage limit based on the first ribbon cable ID, it is possible to set a different usage limit for each ribbon cable, achieving a personalized usage limit for ribbon cables with different characteristics.

[0087] For example, if the first ribbon cable ID is 0x002, and the corresponding number of uses in the data parameters is 0x008, which is less than the limit of 0x100, then the usage permission of the corresponding second ribbon cable ID 0x002 is set to allowed, and the encrypted ribbon cable can then perform data transmission and communication. If the first ribbon cable ID is 0x003, and the corresponding number of uses in the data parameters is 0x300, which is greater than the limit of 0x100, then the usage permission of the corresponding second ribbon cable ID 0x003 is set to disallowed.

[0088] In one implementation, when the usage permission is set to disallowed, the encrypted cable cannot transmit encrypted data.

[0089] Specifically, when the access permission for the encrypted ribbon cable is set to disallowed, encrypted data transmission is not possible. The user can be prompted that the ribbon cable has exceeded its service life and should be replaced with a new one.
