Security management system for authenticating a token by a service provider server

摘要

The present invention relates to a security management system (SYS) for authenticating a token (D) by a service provider server (SP_SERV), wherein said system (SYS) comprises:
- said token (D) comprising a secret key (SKid) and which is adapted to:
- compute a derived secret key (SKps), said computation being a derivation of said secret key (SKid) based on a public key (PKsector) provided by said service provider server (SP_SERV)
- generate at least one pseudonym (Ps) based on said derived secret key (SKps) ;
- said service provider server (SP_SERV) comprising a public key (PKsector) which is adapted to authenticate said token (D) based on said pseudonym (Ps).
