The full name of MD5, Message-Digest Algorithm 5, fifth edition of the Message Digest Algorithm, is one of the widely used hashing algorithms currently used in the computer field to ensure the integrity and consistency of information transfer. The MD5 algorithm has the function of changing data operation into another fixed length value, is the basic principle of a hash algorithm, adopts the MD5 algorithm to encrypt software updating data to generate a 128bits encryption key with 32 characters, carries out position replacement processing on the (n + 1) th bit and the (n-1) th bit of the encryption key to obtain a string of deformed keys, wherein n is more than or equal to 2 and can be set by self,
the DES algorithm uses a 64-bit key to transform 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 replacement IP is carried out; after the initial replacement of the IP, the plaintext data is further divided into two parts, a left part and a right part, each part having 32 bits, denoted by L0, R0; under the control of a secret key, 16 rounds of operation are carried out; 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 cipher text. And encrypting the ciphertext data block by adopting a preset software encryption mechanism to form ciphertext data, and completing the pre-encryption of the software updating 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 Chaining mode), CTR: counter (Counter mode), CFB: cipher Feedback (Cipher Feedback mode) or OFB: output Feedback (Output Feedback mode). And after pre-encryption of the software updating data is completed, storing the software updating data in the electronic medium.

decrypting the pre-encrypted software updating data by adopting a preset software decryption mechanism to obtain a ciphertext data block;
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 operation of the encryption process, and the decryption process like DES is in principle the same as the encryption process, with few differences:
if the using sequence of the sub-keys is K1 and K2 … … K16 when encrypting, then the using sequence of the sub-keys is K16 and K15 … … K1 when decrypting;
the input is 64-bit cipher text, and the output is 64-bit plaintext;
the encryption algorithm is circularly moved to the left while the decryption algorithm is circularly moved to the right when the key is generated.
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 acquires the encryption parameters during encryption and acquires the software updating data after decryption. The software updating data is encrypted and then stored in the electronic medium, so that data stealing caused by the loss of the electronic medium is prevented, and the safety of the data is better ensured.
The technical scheme disclosed by the invention can safely and reliably realize the software updating and prevent the data from being tampered when the software is updated.
