Abstract

The invention provides an encryption method and device, a decryption method and device and a security system of RFID asset information. The encryption method comprises the following steps: reading original RFID asset information data, wherein the original RFID asset information data comprises a public key; preprocessing the original RFID asset information data to obtain preprocessed data; generating a random number, calculating a function value of a first elliptic curve point of the random number, and verifying the public key; calculating a first key derived function value of a second elliptic curve point of the public key passing the verification and performing result verification; performing bitwise exclusive-or calculation on the horizontal and vertical coordinates of the first key derived function value passing verification and the preprocessed data to obtain a first exclusive-or value; performing hash calculation on the values of the abscissa and the ordinate of the first key derived function value passing verification and the splicing value of the preprocessed data to obtain a first Hash value; and splicing the function value of the first elliptic curve point related to the random number, the first hash value and the first XOR value to obtain ciphertext data related to the RFID asset information.

Description

technical field [0001] The disclosure belongs to the field of data security, and in particular relates to an RFID asset information encryption method and device, a decryption method and device, and a security system. Background technique [0002] As the economic foundation of individuals and enterprises, assets are the basic guarantee for the survival of individuals and enterprises. If there is a problem with asset security, it will cause direct economic losses. The identification barcodes used in traditional information asset management are easy to copy, so asset information security There will be great dangers. [0003] RFID radio frequency technology is a kind of automatic identification technology. It performs non-contact two-way data communication through radio frequency, and uses radio frequency to read and write recording media such as electronic tags or radio frequency cards, so as to achieve the purpose of identification and data exchange. At present, RFID radio fr...
