This book constitutes the refereed proceedings of the 15th Australasian Conference on Information Security and Privacy, ACISP 2010, held in Sydney, Australia, in July 2010. The 24 revised full papers presented were carefully reviewed and selected from 97 submissions. The papers are organized in topical sections on symmetric key encryption; hash functions; public key cryptography; protocols; and network security.
