Database authentication revisited
Database authentication via cryptographic checksums represents an important approach to achieving an affordable safeguard of the integriry of data in publicly accessible database systems against illegal manipulations. This paper revisits the issue of database integrity and offers a new method of safeguarding the authenticity of data in database systems. The method is based on the recent develop...
متن کاملMessage Authentication, Revisited
Traditionally, symmetric-key message authentication codes (MACs) are easily built from pseudorandom functions (PRFs). In this work we propose a wide variety of other approaches to building efficient MACs, without going through a PRF first. In particular, unlike deterministic PRF-based MACs, where each message has a unique valid tag, we give a number of probabilistic MAC constructions from vario...
متن کاملSymmetric Key Authentication Services Revisited
Most of the symmetric key authentication schemes deployed today are based on principles introduced by Needham and Schroeder [17] more than twenty years ago. However, since then, the computing environment has evolved from a LAN-based client-server world to include new paradigms, including wide area networks, peer-to-peer networks, mobile ad-hoc networks and ubiquitous computing. Also, there are ...

متن کاملAuthentication Revisited: Flaw or Not, the Recursive Authentication Protocol
Authentication and secrecy have been widely investigated in security protocols. They are closely related to each other and variants of definitions have been proposed, which focus on the concepts of corresponding assertion and key distribution. This paper proposes an onthe-fly model checking method based on the pushdown system to verify the authentication of recursive protocols with an unbounded...
