The number of papers submitted to INDOCRYPT 2004 was 181, out of which 147 papers conformed to the speci?cations in the call for papers and, therefore, were accepted to the review process. We should note that many of the papers that were not accepted were of good quality but only the top 30 papers were accepted.
