TL;DR: This book contains the papers presented at the second conference in what has become an ongoing series of joint international conferences on cryptography and coding theory.
Abstract: Cryptography and coding theory are both rapidly evolving areas involving the application of discrete mathematics to problems in computing and electronic engineering. Such is the close relationship between both the underlying mathematics and the application domains that a joint international conference was organized in late 1986. This book contains the papers presented at the second conference in what has become an ongoing series.

TL;DR: It is shown that the bidirectional BMAC technique is not a one-way function, which means that it should not be used for authenticating multicast messages.
Abstract: The 1988 version of the message encryption and authentication procedures for Internet electronic mail makes use of bidirectional MAC (BMAC). When used for multicast electronic mail it is important that this BMAC act as a one-way function. It is shown that it is not a one-way function, which means that the BMAC technique should not be used for authenticating multicast messages. >
