Does anyone know if there is a validation suite for the IDEA cipher? I want to be able to verify an implementation on the TMS320 digital-signal processor.

The NIST has such a test suite for the DES, but I haven't heard anything about IDEA.

There is some sample data included in the appendix to the IDEA description (chapter 3 or someone's thesis) which is floating around the network. This sample data should allow at least a partial validation of your cipher implementation, and arbitrary amounts of it can furthermore be generated by using the sample C implementation contained in the same appendix. This document is widely available, but until the end of the week I have stored it in: ftp.mq.edu.au:/home/ifarqhar/idea-eurocrypt90.zip I do not know how much longer it will remain after Friday, as I will be leaving my position here on that day and moving accounts. Ian.
