Abstract
The client requests from the authentication and authorization server a capability for accessing the target server. The authentication and authorization server sends client a capability (cap) comprising the public key (pub) of the client, said capability being signed with a private key (priv) of the authentication and authorization server. The client sends the capability (cap) to the target server. If the capability is valid, the target server grants the client access and a data exchange session can be initiated. The disclosed protocol is scalable, as it does not require individual configuration of each target server device, allows revocation of user access within reasonable time, stores no compromisable secret data on any target server device, enables individual access permission per user, and accountability of each user.
