key embedded cipher

Abstract

The public key embedded cipher of the present invention includes a key embedded algorithm module and a cryptographic system composed of the algorithm module. The key embedded algorithm module integrates the encoding / decoding function and the key generation function, and the key is configured in asymmetric and symmetric ways in a separate algorithm module. The key algorithm module is divided into a parent function module and a sub-function module. The cryptographic system consists of a management center and multiple user terminals. The management center uses the parent function module to generate sub-function modules with different key settings, and distributes the sub-function modules to users. The key distribution is automatically completed during this process. The key has a uniformly set key number, and the user manipulates the key through the key number. The cryptographic system uses the key algorithm module and its key configuration to establish a hidden key communication mechanism. The effect is that the system provides three information security functions of confidentiality, authenticity and non-repudiation, but neither is transmitted between users. key, and does not directly disclose the key.

Description

technical field [0001] The invention relates to key embedded ciphers and belongs to the technical field of information security. Background technique [0002] Cryptography is the core technology to ensure network information security. The ciphers currently used in practice can be divided into two categories according to the different key forms: symmetric cryptography and asymmetric cryptography (public key cryptography). [0003] In a symmetric cryptosystem, the same key is used for encryption and decryption. The security of this type of cipher mainly depends on the secrecy of the key, and the communication parties generally need to transfer the key through a secure channel. The main advantage of symmetric cryptography is that the algorithm is simple and the operation speed is fast, but the disadvantage is that the key management is complicated, which is also the biggest problem of symmetric cryptography in practical applications. [0004] In a public key cryptography sys...
