Correcting flaws in Mitchell’s analysis of EPBC

    Efficient error-Propagating Block Chaining (EPBC) is a block cipher mode intended to simultaneously provide both confidentiality and integrity protection for messages. Mitchell pointed out a weakness in EPBC and claimed that this permits a forgery attack. This paper corrects a flaw in Mitchell’s analysis and shows that the attack is no better than brute force of the integrity check vector.
