Method and system for information secrecy storage by encoding

Abstract

The invention relates to the information secrecy storage technology field and discloses a method for information secrecy storage by encoding. The method includes the follow steps: step 1: encoding original information to obtain intermediate process codes, a final code, and relative parameters corresponding to the number of times of encoding; step 2: storing the intermediate process codes, the final code and the relative parameters corresponding to the number of times of encoding, then safely storing a code sequence obtained by one time or multiple times of encoding and the relative parameters; step 3: restoring the original information according to the final code, the intermediate process codes and the relative parameters corresponding to the number of times of encoding through the inverse of the encoding. According to the invention, computation of the encryption algorithm is not needed, negotiation and distribution of an encryption key is not required, a large amount of calculations and intermediate storage processes are not required, and the resource consumption of the method is negligible. The method has the characteristics of high performance and short time delay, and only needs to encode in a fixed format.

Description

technical field [0001] The invention relates to the technical field of information security storage, and the invention discloses a method and a system for realizing information security storage by using coding. Background technique [0002] In order to ensure data security, a general method is to encrypt data that needs to be kept secret. A common method of encrypting data is to protect the original information through a data encryption algorithm. The original information is encrypted by an encryption algorithm to obtain a ciphertext. Only those who have the key can decrypt the ciphertext and restore the original message. [0003] However, cryptographic operations are generally more complicated, so there are certain requirements for the hardware for encryption and decryption operations. After the information is encrypted, both the ciphertext and the key must be safely stored, and the amount of information is relatively large. At the same time, it is necessary to set the key...
