s6: and (3) the operation result corresponds to an output sequence, and encryption is completed: placing the operation result obtained in the step S5 at the position corresponding to the extended code in the output sequence and the extended sequence to complete the encryption process;
the decrypting step includes:
s7: determining an operational operator: performing position matching correspondence on the output sequence obtained in the step S6 according to the spreading sequence in the step S3, and determining the position of data in the output sequence according to the spreading code value on the corresponding spreading sequence position; in step S4, the obtained numerical value corresponds to an operation operator of the logical operation;
s8: and (3) operation: performing logical operation on the data in the output sequence and the data of the corresponding bit in the key according to the operation operator determined in the step S7 to obtain the data of the corresponding position in the input source string in the step S1;
s9: acquiring an input source string, and finishing decryption: continuing the step S7 and the step S8 until the complete input source string in the step S1 is obtained through operation, and completing decryption to obtain source data needing decryption;
the input source string and the extended sequence adopt a position corresponding mode, the extended sequence and the operation operator adopt a numerical value corresponding mode, and the extended sequence and the output sequence adopt a block corresponding mode.
In the encryption AND decryption processes, the calculation operation mode may adopt a general logic operation mode, AND the adopted operation operators are AND, OR, XOR, NXOR, NOT, NAND, NOR, such as: AND for 1, OR for 2, NOT for 3, XOR for 4, NXOR for 5, NAND for 6, AND NOR for 7; the operation operator needed by the operation in step S5 is determined by comparing the spreading code values in the spreading sequence with the numbers corresponding to the logical operators.
If the input data string is 0x03,0x09,0x55 in step S1; in step S2, a spreading sequence having a spreading code value of 1,3, a secret key of 0x42,0x36,0x01,0x06, and an output sequence are prepared; comparing the length of the input source string with the length of the spreading sequence, wherein the number of spreading codes of the spreading sequence in the step S2 is 2, the number of data strings in the step S1 is 3, the spreading sequence needs to be extended to 3 number strings, for example, the spreading sequence is added with a number 2, namely the spreading sequence is spread to be 1,3,2, and the blocks corresponding to the output sequence are 1 data, 3 data and 2 data respectively; step S4, an integer of (expansion bit value/2) +1 is taken, the rule of an operation operator in corresponding logic operation is determined through the calculation result, for example, 1,3,2 data strings in an expansion sequence, the corresponding result number is 1,2 is obtained through the operation of the step S4, AND the corresponding operation operator is AND, OR, OR; in step S5, the input source string 0x03,0x09,0x55 AND the key data string 0x42,0x36,0x01,0x06 are logically operated according to an operation operator, AND 0x03 AND 0x42 are subjected to an AND operation to obtain a block [0x2], AND 0x09 AND 0x36 are subjected to an OR operation to obtain a block [0x56,0x3f,0x11], AND 0x55 AND 0x01 are subjected to an OR operation to obtain [ x43,0x57], while the extra data 0x06 in the key does not participate in the operation because the input source string data does not correspond to the key data. The operation results [0x2], [0x56,0x3F,0x11], [0x43,0x57] obtained by the logical operation in step S5 are placed at positions of the output sequence corresponding to the extended sequence values, and the resulting output sequences are 0x2,0x56,0x3F,0x11,0x43,0x57, and the encryption process is completed. In summary, the length of the input source string is 3 data, the length of the encrypted output sequence is 6 data, and the length of the output sequence is longer than that of the input source string, so that the difficulty of communication transmission is increased, and the security of file transmission is improved. And the value of the spreading code numerical string of the spreading sequence is indefinite, and the value can be randomly selected, so that the length of the output sequence is indefinite, and the decoding difficulty is further increased.
Example 2
On the basis of embodiment 1, the extension of the length of the extended sequence or the length of the key is in the form of a circular string, the looping position may start from the first position of the length of the extended sequence or the key, or from other positions after the first position, and the looping position in the encryption step is consistent with the looping position in the decryption step.
The spreading code value in the spreading sequence in the above step S2 has a length of 15 digits, and bytextendcode = {1,3,2,6,3,1,4,6,8,1,2,3,4,5,1}, and if the length of the spreading code needs to be extended to 20 digits to be consistent with the length of the input source string, the subsequent digits may be circulated after the last digit 1 and then the first digit 1 or the second digit 2, or circulated from the other digit positions to form a ring string. Similarly, in step S5, the key data string length is compared with the input data string length, and if the key data string length is not long enough and needs to be extended, the above-mentioned consistent looping principle is adopted.
It should be noted that, in the encryption process, the same convention needs to be performed in the decryption process in the manner of the circular string adopted for the length of the spreading sequence or the length of the key.
Example 3
On the basis of the embodiment 1, the input source string data in the step S1 is preprocessed by the custom byte. For example, the byte data may be shifted to the left by several bits or to the right by several bits. If alpha is defined as moving 4 bits to the left, beta is defined as moving 4 bits to the right, and gamma is defined as moving 3 bits to the left, if the input source string is 0x43,0xA4,0x 43 is subjected to alpha operation to obtain 0x34; performing beta operation on 0xA4 to obtain 0x4A, and performing gamma operation on 0xA4 to obtain 0x25, namely preprocessing input source string data 0x43,0xA4 and 0xA4 to obtain 0x34,0x4A and 0x25, and further enhancing the security performance of the file to be encrypted.
The protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention.
