Abstract

This document specifies a new authorization data container for Kerberos, called the CAMMAC (Container Authenticated by Multiple MACs). The Abstract Syntax Notation One (ASN.1) type implementing the CAMMAC concept is the AD-CAMMAC, which supersedes the AD-KDC- ISSUED authorization data type specified in [RFC4120]. This new container allows both the receiving application service and the Key Distribution Center (KDC) itself to verify the authenticity of the contained authorization data. The AD-CAMMAC container can also include additional verifiers that "trusted services" can use to verify the contained authorization data.

     Kerberos Authorization Data Container Authenticated by Multiple                   Message Authentication Codes (MACs)

Abstract

   This document specifies a Kerberos authorization data container that    supersedes AD-KDC-ISSUED.  It allows for multiple Message    Authentication Codes (MACs) or signatures to authenticate the    contained authorization data elements.  The multiple MACs are needed    to mitigate shortcomings in the existing AD-KDC-ISSUED container.    This document updates RFC 4120.
