The widespread use of wireless cellular networks has made security an ever increasing concern. GSM is the most popular wireless cellular standard, but security is an issue. The most critical weakness in the GSM protocol is the use of one-way entity authentication, i.e., only the mobile station is authenticated by the network. This creates many security problems including vulnerability against m...

Entity authentication becomes ubiquitously necessary in pervasive computing environments. We provide taxonomy of entity authentication between keys and locks. Based on the discussion, we propose a novel authentication approach for pervasive computing environments. A person uses a single device, the Master Key, which aggregates all his digital keys for entity authentication. The Master Key initi...

An algorithm or an authentication system for a loW-cost authenticating device such as a radio frequency identi?cation (RFID) tag, or a sensor node are provided, by Which authen tication is processed e?iciently Without requiring a random number. A claimant entity attempting to be authenticated and a verifying entity to authenticate the claimant entity, share a plurality of secret keys so that au...

Authentication is the process by which the identity of an entity is established. Authenticating entities present credentials, such as passwords or certificates, as evidence of their identity. The entity is deemed authentic where presented credentials are valid and sufficient. Note that authentication does not determine which entities should be given access, but only verifies that an entity is w...

Authentication is the process by which the identity of an entity is validated. Authenticating entities present credentials, such as passwords or certificates, as evidence of their identity. The entity is deemed authentic where presented credentials are valid and sufficient. Note that authentication does not determine which entities should be given access, but only verifies that an entity is who...

Authentication is the art of confirming the truth of an attribute of an entity. Entity may be a person. If a entity is a person it can authenticate with the help of its traits such as his facial attribute, fingerprinting attribute, retina attribute, palm attribute, signature of a person, password, token attributes etc. There are so many attacks to which these techniques are vulnerable. So, toda...

Entity authentication provides confidence in the claimed identity of a peer entity, but the manner in which this goal is achieved results in different types of authentication. An important factor in this regard is the order between authentication and the execution of the associated session. In this paper, we consider the case of post-session authentication, where parties authenticate each other...

This paper provides the first analytical and practical treatment of entity authentication and authenticated key exchange in the framework of Tree Parity Machines (TPMs). The interaction of TPMs has been discussed as an alternative concept for secure symmetric key exchange. Several attacks have been proposed on the non-authenticated principle. Adding and some extra entity authentication method i...
