Problems solved by technology

Among the two existing cryptographic technologies, 3DES, IDEA, and AES belong to single-key secrecy, RSA, DSS, ECC, etc. belong to public key signature, and comprehensive types such as PGP, PKI, IPsec, etc. belong to the combined application of two cryptographic systems. The biggest flaw of the application technology is that it separates encryption and authentication, cannot effectively link users and cryptographic systems, and is difficult to resist third-party attacks
Moreover, the implementation of these technologies is inefficient, complicated and cumbersome, and key management is a major problem in the world

Embodiment 1

[0159] Embodiment 1, software and hardware hybrid embodiment

[0160] figure 2 and image 3 It is a preferred software and hardware hybrid embodiment of the present invention, figure 2 The key generation / regenerator is implemented with a digital chip or smart card to form a hardware system, image 3 A software program is used to realize the formation of an encryption authentication software system, and the hardware system and the software system realize information interaction through a USB interface or a sensing interface. Each digital chip or smart card has a globally unique hardware serial number-space code, which determines the range of vector key space that the hardware can generate and reproduce. In practical applications, the serial number must be used by an authoritative third party The user's identity information is bundled with the serial number and made public so that other users can verify their identity and communicate directly with them.

Abstract

The invention discloses a novel vector encryption authentication mechanism and relates to a vector cryptography method, belonging to the technical field of information security. The method comprises the following steps: a cipher system selects a large number encryption key space M which is twice divided into 2*2 encryption key subspaces which are provided with 2 vectors with different orientations in order that each cipher system of the system possesses a unique encryption key subspace and a unique decryption key subspace; according to the method, the novel vector encryption authentication mechanism can be constructed; the mechanism adopts a hardware tamperproof encryption key generation / regeneration technology to realize the secondary division of the large number encryption key space and endow the encryption key with vector property; and the mechanism adopts a dissymmetrical symmetric algorithm array for encryption / decryption, thereby realizing high strength security, anti-replay, integral control, identity authentication and digital signature and having no problem of the management of the encryption key.

Description

technical field [0001] The invention belongs to the basic technical field of information security, and specifically relates to a vector cipher encoding method and a novel vector cipher authentication mechanism constructed by the method. Background technique [0002] Cryptography technology is one of the main basic technologies for ensuring the security of information networks today. According to the different forms of keys used, cryptographic technology can be divided into symmetric cryptosystems and asymmetric cryptosystems or single-key (private key) cryptosystems and double-key (public key) cryptosystems. key) cryptographic system. In today's network environment, in order to ensure the security of information network and information, it is necessary to use cryptographic technology in order to realize the confidentiality of information, the identity authentication of information generators, digital signatures to prevent repudiation, and digital fingerprints to prevent infr...
