SECURITY MANAGEMENT SYSTEM FOR REVOKING A TOKEN FROM AT LEAST ONE SERVICE PROVIDER TERMINAL OF A SERVICE PROVIDER SYSTEM

摘要

The present invention relates to a security management system (SYS) comprising a plurality of tokens (SE), a revocation management system (RM_SYS) and a service provider system (SP_SYS) comprising at least one service provider terminal (SP_T), wherein: - each token (SE) comprises at least one status attribute (R), said at least one status attribute (R) indicating if a token (SE) is revoked or not from at least one service provider terminal (SP_T) of said service provider system (SP_SYS) ; - said revocation management system (RM_SYS) comprises a revocation management terminal (RM_T), said revocation management terminal (RM_T) comprising a token status list (Lr) which comprises first data (D1) corresponding to the tokens (SE) which are revoked or corresponding to the tokens (SE) which are not revoked, and said revocation management terminal (RM_T) being adapted to : - read said first data (D1) from a token (SE) ; - check said first data (D1) against the token status list (Lr) ; - update the at least one status attribute (R) of said token (SE) according to said checking ; - said service provider terminal (SP_T) is adapted to verify if a token (SE) is revoked from it, or not, said verification being based on the at least one status attribute (R) of said token (SE).
