A New Approach to Secure Logging

Abstract. The need for secure logging is well-understood by the security professionals, including both researchers and practitioners. The ability to efficiently verify all (or some) log entries is important to any application employing secure logging techniques. In this paper, we begin by examining state-of-the-art in secure logging and identify some problems inherent to systems based on trusted third-party servers. We then propose a different approach to secure logging based upon recently developed Forward-Secure Sequential Aggregate (FssAgg) authentication techniques. Our approach offers both space-efficiency and provable security. We illustrate two concrete schemes
