Abstract

This specification describes a family of authentication mechanisms called the Salted Challenge Response Authentication Mechanism (SCRAM) which addresses the requirements necessary to deploy a challenge- response mechanism more widely than past attempts (see Appendix A and Appendix B). When used in combination with Transport Layer Security (TLS; see [RFC5246]) or an equivalent security layer, a mechanism from this family could improve the status quo for application protocol authentication and provide a suitable choice for a mandatory-to-implement mechanism for future application protocol standards.

Abstract

   The secure authentication mechanism most widely deployed and used by    Internet application protocols is the transmission of clear-text    passwords over a channel protected by Transport Layer Security (TLS).    There are some significant security concerns with that mechanism,    which could be addressed by the use of a challenge response    authentication mechanism protected by TLS.  Unfortunately, the    challenge response mechanisms presently on the standards track all    fail to meet requirements necessary for widespread deployment, and    have had success only in limited use.

   This specification describes a family of Simple Authentication and    Security Layer (SASL; RFC 4422) authentication mechanisms called the    Salted Challenge Response Authentication Mechanism (SCRAM), which    addresses the security concerns and meets the deployability    requirements.  When used in combination with TLS or an equivalent    security layer, a mechanism from this family could improve the status    quo for application protocol authentication and provide a suitable    choice for a mandatory-to-implement mechanism for future application    protocol standards.
