The Diameter base protocol specification [2] defines security protection between neighboring Diameter peers. Diameter mandates that peer connections must be protected by Transport Layer Security (TLS) [6] for TCP, by Datagram TLS (DTLS) [7] for the Stream Control Transmission Protocol (SCTP), or by security mechanisms that are independent of Diameter (such as IPsec [5]). These security protocols offer a wide range of security properties, including entity authentication, data-origin authentication, integrity protection, confidentiality protection, and replay protection. They also support a large number of cryptographic algorithms, algorithm negotiation, and different types of credentials. It should be understood that TLS/DTLS/IPsec in the Diameter context does not provide end-to-end security unless the Diameter nodes are direct peers, i.e., neighboring Diameter nodes. The current Diameter security is realized hop by hop.
