Abstract

The Kerberos error message, as defined in RFC 1510, is transmitted to the client without any integrity assurance. Therefore, the client has no means to distinguish between a valid error message sent from the KDC and one sent by an attacker. This draft describes a method for assuring the integrity of Kerberos error messages, and proposes a consistent format for the e-data field in the KRB_ERROR message. This e-data format enables the storage of cryptographic checksums by providing an extensible mechanism for specifying e-data types.
