Abstract

The invention provides encryption and decryption algorithms and a data encryption device. A data encryption method comprises the following steps: acquiring encryption parameters in a first linear feedback shift register and a second linear feedback shift register; encrypting encryption data in a feedback module according to the encryption parameters to obtain single-bit byte data; executing xor operation on the single-bit byte data and programming parameters to generate single-bit encrypted data. With adoption of the method, the security of one-way data transmission of half-duplex low-frequency RFID is improved, and the method has the advantages of being high in encryption and decryption speed, easy to implement, high in encryption strength, good in security and wide in application, and is applicable to software and hardware.

Description

technical field [0001] The present invention relates to the technical field of data encryption, and more specifically, to a data encryption method and a data encryption device. Background technique [0002] In related technologies, the so-called half-duplex means that only one action occurs within a period of time, and the encrypted data is encrypted with the same key and the same type of random number to realize data transmission in the half-duplex state. When the number is large, the security of the data cannot be increased. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] For this reason, the object of the present invention is to provide a kind of data encryption method and a kind of data encryption device, by designing a kind of new data encryption method, the safety of half-duplex low-frequency RFID one-way data transmission has been improved, and it has the function of e...
