Research of S50 Based Electronic Label Authentication Algorithm

with the development of big data and Internet of things, the application of electronic label have been more and more widely. The data security of electronic label has a direct impact on the security of the carrier, data encryption technology is a common means to ensure data security. This algorithm takes S50 as an example, put forward a kind of encryption algorithm of high-frequency electronic label, using ISO/IEC14443/Type-A protocol, with S50 electronic label UID code as calculation factor, with customized long string as divergence factor, and the key system of 16 sector is calculated by PSAM card, so as to realize the security of electronic label S50 authentication, at the same time realize the internal logic authentication and external MAC code authentication of the electronic label.
