Background Art

[0002] The usual signal source software will add additional functions based on the basic functions. These functions are generally activated selectively by users who purchase keys. The functions may be composed of pure software or a combination of software and hardware. Based on different applications, the key algorithm can also be one-way (encryption into a summary) or two-way (encryption and key decryption can derive the encrypted content). The key usually exists as a set of numbers, but there are some exceptions where there are combinations of letters and arrays, when the key is composed of numbers and letters. There will be some letters and arrays that are very similar, such as 0 (number 0) and O (capital o), etc., which can easily lead to user misunderstanding and incorrect input.

[0048] As a preferred embodiment of the present invention, the secret key includes a random content portion Remaining, a valid ciphertext Encrypt and a parsing bit Analysis, and the valid ciphertext Encrypt and the parsing bit Analysis are combined and arranged and stored in the secret key, or are shuffled and stored in the secret key.

[0049] As a preferred implementation manner of the present invention, the first bit of the analysis bit Analysis stores a dictionary interpretation value, and the last 4 bits store a CRC interpretation value.

[0050] As a preferred embodiment of the present invention, the plaintext is encrypted in step (1-2), specifically comprising the following steps:

[0051] (1-2.1) Calculate and record the position of the valid ciphertext Encrypt and the position of the analysis bit Analysis in the remaining part of the random content;

[0052] (1-2.2) Translate the position of the valid ciphertext Encrypt and the position of the analysis bit Analysis into readable characters according to the positioning dictionary;

[0053] (1-2.3) Fill the remaining digits of the random content part Remaining with random numbers and translate them into readable characters according to the random dictionary.

[0054] The device for realizing signal source option key generation and analysis processing of the present invention, wherein the device comprises:

[0055] a processor configured to execute computer executable instructions;

[0056] The memory stores one or more computer executable instructions. When the computer executable instructions are executed by the processor, the various steps of the method for generating and analyzing the signal source option key are implemented.

[0057] The processor of the present invention is used to implement signal source option key generation and analysis processing, wherein the processor is configured to execute computer executable instructions, and when the computer executable instructions are executed by the processor, the various steps of the above-mentioned method for implementing signal source option key generation and analysis processing are implemented.

[0058] The computer-readable storage medium of the present invention stores a computer program thereon, and the computer program can be executed by a processor to implement the various steps of the above-mentioned method for realizing signal source option key generation and analysis processing.

[0059] In a specific embodiment of the present invention, a method for generating and decrypting a signal source limited display key is provided.

[0060] The technical solution adopted in this scheme is to perform random multi-dictionary position mapping on the plaintext content, so that the plaintext is converted into custom display content, thereby eliminating the content that you do not want to be displayed in the ciphertext. In addition, since multiple dictionaries are randomly selected and random codes are used to fill in the vacancies, the obtained ciphertext is highly random and has a high degree of concealment.

[0061] Figure 1 and Figure 2 This is a simple diagram of key generation and use, which only describes the overall process relationship. The core is the encryption and decryption algorithm, which will be explained in detail below.

[0062] Since the algorithm is a multi-dictionary encryption composed of dictionaries as the basis, it is necessary to define dictionaries of different categories and dictionary contents. The number of dictionaries is defined according to actual needs. If the processing flow is more complicated, multiple interpretation dictionaries are defined.

[0063] The key algorithm defines the structure of the generated key content: random content filling, valid ciphertext, and parsing bit, where the length of the parsing bit is mainly determined by the encryption process. For this algorithm, the longer the key, the higher the security.

[0064] Assume that in a specific embodiment, the secret key Key is 30 bits, the analysis bit Analysis is 5 bits, and the effective ciphertext Encrypt is 10 bits.

[0065] From the above assumptions, we can know that the secret key is composed of Figure 3 As shown. The random number length Remaining By Length Key Subtract Length Encrypt and Length Analysis The sum of. Figure 4 As shown in the figure, the valid ciphertext Encrypt and the analysis bit Analysis can be combined and stored in the secret key Key, or they can be stored in a random order in the secret key Key. If they are stored in a random order, the Remaining bits need to be occupied to record the storage location.

[0066] The parsing bit is composed as follows Figure 4 shown.

[0067] The first bit of the parsing bit stores the dictionary interpretation value, and the last 4 bits store the CRC interpretation value.

[0068] In the encryption process, a real-time random algorithm is first used to select plaintext characters, i.e., readable characters DicL (0-255 random bytes). Then, some algorithms (modulus or other forms) are used on the readable characters DicL to obtain the actually selected encryption dictionary index DicRL. The corresponding encryption dictionary is found according to the DicRL index. The character value of the plaintext character set is used as the position information. The actual character at the corresponding position in the encryption dictionary is found according to the position information. That is, each character of the plaintext is divided by the Base Custom Take the remainder to get the location of the dictionary, and then get a new character set (ciphertext). The first bit of the parsing bit stores DicL, and the second to fifth bits store the CRC calculation value to ensure the integrity of the secret key. On the CRC dictionary (the dictionary is a fixed sequence readable character set generated by the algorithm), use the same position mapping as above to find the readable character. Among them, the encryption dictionary DicRL, positioning dictionary and CRC dictionary have different byte structures and belong to different dictionaries.

[0069] Since Encrypt and Analysis are stored randomly, the bits in the Remaining part are used to record the position of Encrypt and Analysis. They can be calculated using algorithms such as remainder and bit operations, and then translated into readable characters according to the positioning dictionary. The remaining Remaining is filled with random numbers and translated into readable characters according to the random dictionary. Among them, the first bit of the analysis bit is defined by the author, and the remaining part can be translated using the encryption dictionary or generated randomly.

[0070] The decryption process is the reverse of the encryption process. The Encrypt and Analysis locations are obtained by reversing the above steps, and then they are taken out separately. CRC is used for integrity verification, and the original content is calculated by reverse calculation.
