Information security digital encryption method based on one-time use codebook

Abstract

The invention discloses an information security digital encryption method based on a one-time use codebook. Front and back background information is formed by utilizing host characteristic informationof afile and specific information of communication equipment used by the file; therefore, a double-track double-block K grouping digital vector correlator structure is formed; and partial feature information is extracted the background information to serve as a digital key for encrypting the plaintext information, encryption modulation is carried out on asymbol dictionary by adopting a functionaldynamic encryption algorithm, a once-used digital password book with the background information is generated, and a public digital password of the plaintext information is generated. The informationsecurity digital encryption method based on the one-time use codebook provided by the invention is effectivelycombined with a third-party transmission SSL / TLS communication protocol cryptosystem, so that big data and information security in an Internet environment are effectively guaranteed. The method is suitable for completing an encryption task of plaintext information by utilizing the characteristic that private confidential information and public information are asymmetric under the condition that background information of an internet environment is not completely transparent.

Description

technical field [0001] The invention relates to an information security digital encryption method based on a one-time codebook. Background technique [0002] There is a wide variety of technologies associated with cryptography, both invisible and visible, digital and non-digital. However, they all have a common feature: digital cryptography technology generated around multiple keys generated by a fixed codebook, and each cryptography technology has a close relationship. [0003] A general cryptographic system refers to the information host A of information (message) W, using the encryption algorithm of symmetric key Q or asymmetric private key PW and public key GW to perform public key encryption processing on W that needs to be encrypted, and generate The public password MW, and pass the password MW to the third party C. [0004] After receiving the encrypted password MW, the access receiver B uses the private key and decryption algorithm to decrypt the MW and restore the...
