Mobile distributed authentication protocol

Networks access control is a crucial topic and authentication is a pre-requisite of that process. Most existing authentication protocols (for example that used in the GSM mobile network) are centralised. Depending on a single entity is undesirable as it has security, trust and availability issues. This paper proposes a new protocol, GSM-secure network access protocol (G-SNAP). In G-SNAP, the authentication procedure and network access control is handled by a quorum of authentication centres. The advantages of the novel protocol include increased security, availability and distributed trust
