A kind of encryption method and system based on zynq device

Abstract

The invention relates to an encryption method and system based on a ZYNQ device, wherein the method comprises the steps that: the ZYNQ device reads any key value of multi-key equipment; an encryptionprogram is determined according to the key value; and, information to be encrypted is encrypted according to the encryption program. By means of the technical scheme provided in the embodiment, the ZYNQ device reads a certain key value in the multi-key equipment; the corresponding encryption program is determined according to the key value; therefore, the information to be encrypted is encrypted according to the encryption program; the encrypted information is obtained; therefore, on one hand, the technical shortcoming that a large number of algorithms can be realized by adoption of a large number of programmable devices in the prior art can be avoided; on the other hand, the technical effect of encrypting the information to be encrypted rapidly and effectively is realized; and thus, the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to an encryption method and system based on a ZYNQ device. Background technique [0002] With the improvement of security awareness, the use of cryptographic devices has become more and more extensive, and the requirements for cryptographic devices have become higher and higher. The cryptographic algorithms currently in use include: SM1, SM2, RSA, etc. [0003] In the prior art, when encrypting a card to obtain a cipher card by means of a calculation method, there are mainly two methods, one of which is: adopting a large number of programmable devices to implement all algorithms. However, since the algorithm takes up a lot of resources during calculation, the requirement for the capacity of the programmable logic device is relatively high, so the equipment cost is difficult to control. Another method is: using an external algorithm chip to implement, but because one c...

Problems solved by technology

However, since the algorithm takes up a lot of resources when performing calculations, the requirements for the capacity of the programmable device are relatively high, so the equipment cost is difficult to control

Another method is: use an external algorithm chip to implement, but because a chip intelligently implements the centralized algorithm, and the system complexity of the chip is very high, so that the encryption cost is not easy to control
