Embodiment

[0021] figure 1 It is the layout diagram of evolution cryptographic chip module. Wherein, the evolution encryption chip is connected with the computer through the PCI interface. As a high-speed data port in the computer, the PCI interface mainly completes the input and output of data, including the initial data for evolution, the encryption / decryption data and keys that need to be processed. The intelligent calculation part includes a fitness value calculation module, an evolution operator module and a true random number generator. The true random number generator is connected with the evolution processing part through the evolution operator module, and the intelligent calculation part is connected with various modules of the DES algorithm. The cryptographic chip is provided with a testability design module and an online CED detection module, and the two modules are connected with various modules of the DES algorithm.

[0022] The fitness value calculation module includes di...

Abstract

The invention relates to an evolutionary password chip. The evolutionary password chip is manufactured by using the characteristic of infinite reconstruction of a programmable chip and the evolutionary design characteristic of intelligent calculation to dynamically design the algorithm of the key part of the password in real time. The password chip comprises the programmable chip and each part module of a DES algorithm arranged in the chip; each part module of the DES algorithm is connected with an intelligent calculation part; the intelligent calculation part comprises an adaptive value calculating module, an evolutionary operator module and a true random number generator which is connected with an evolutionary processing part by the evolutionary operator module. The algorithm of the key part of the password is realized by an intelligent calculation method.

Description

technical field [0001] The invention relates to a cryptographic chip, in particular to a chip combining evolutionary algorithm, cryptographic design and hardware. Background technique [0002] The automatic design and high-speed implementation of cryptographic algorithms has always been an important research content in the field of cryptography. Research on new computing technology and design platform is of great significance to improve the automatic design capability and security of cryptographic algorithms. [0003] Evolutionary computing is a general problem-solving method developed by people inspired by the long evolution process of nature. It does not need to explicitly describe all the characteristics of the problem, but only needs to generate new and better solutions according to the laws of nature. It adopts simple encoding technology to represent various complex structures, and guides learning and determines the direction of search through genetic manipulation and...
