and encrypting the ciphertext data block by adopting a preset software encryption mechanism to form ciphertext data, and completing pre-encryption of software update data.
MD5, which is known as Message-Digest algorism 5, the fifth edition of the Message Digest Algorithm, is one of the widely used hash algorithms in the current computer field for ensuring complete consistency of information transfer. The MD5 algorithm is used for changing data operation into another fixed length value, which is the basic principle of the hash algorithm, the MD5 algorithm is used for encrypting the software update data to generate a 128-bit encryption key with 32 characters, the n+1th bit and the n-1th bit of the encryption key are subjected to position replacement to obtain a string of deformed keys, n is more than or equal to 2, n can be set by oneself,
the DES algorithm uses a 64-bit key to change a 64-bit plaintext input block into a 64-bit ciphertext output block, and divides the output block into two parts, L0 and R0, each of which is 32 bits. Specifically, 64-bit plaintext data is input, and initial substitution IP is performed; after the IP is replaced initially, the plaintext data is divided into a left part and a right part, and each part is 32 bits and is represented by L0 and R0; under the control of the secret key, carrying out 16 rounds of operation; after 16 rounds, the left part and the right part are exchanged and connected together, and then reverse replacement is carried out; and outputting 64-bit ciphertext. And encrypting the ciphertext data block by adopting a preset software encryption mechanism to form ciphertext data, and completing pre-encryption of software update data. The preset software encryption mechanism may be a common encryption mechanism, and may be an ECB: electronic Code Book (electronic codebook mode), CBC: cipher Block Chaining (cipher block chain mode), CTR: counter (Counter mode), CFB: cipher Feedback (Cipher Feedback mode) or OFB: output Feedback (Output Feedback mode). After the pre-encryption of the software update data is completed, the software update data is stored in an electronic medium.

and decrypting the ciphertext data block by using the deformed key through a data encryption standard DES algorithm to obtain software updating data.
The decryption process is the inverse of the encryption process, as the decryption process for DES is in principle the same as the encryption process, with few differences:
if the use sequence of the subkeys is K1, K2 … … K16 during encryption, the use sequence of the subkeys is K16, K15 … … K1 during decryption;
the input is 64-bit ciphertext, and the output is 64-bit plaintext;
the encryption algorithm is rotated left while the key is generated, but the decryption algorithm is rotated right.
The deformed key in the software development terminal can be transmitted to the software uploading terminal through another electronic medium, and when decryption is carried out, the software uploading terminal obtains the encryption parameters during encryption, and the software updating data is obtained after decryption. The software updating data is stored in the electronic medium after being encrypted, so that the data is prevented from being stolen caused by the loss of the electronic medium, and the safety of the data is better ensured.
According to the technical scheme, the software can be safely and reliably updated, and data is prevented from being tampered during software updating.
