Deniable authenticated protocol is a new and attractive protocol compared to the traditional authentication protocol. It allows the appointed receiver to identify the source of a given message, but not to prove the identity of the sender to a third party even if the appointed receiver is willing to reveal its private key. In this paper, we first define a security model for certificateless denia...

The Secure Shell Protocol (SSH) is a protocol for secure remote login and other secure network services over an insecure network. This document describes a general purpose authentication method for the SSH protocol, suitable for interactive authentications where the authentication data should be entered via a keyboard (or equivalent alphanumeric input device). The major goal of this method is t...

In distributed system environment, security of system is an important issue whose basis is authentication protocol. Authentication protocol requires a authentication server which will decide login of users, and the server will be the main target of attacks. In this paper, we present a distributed authentication protocol model, whose goals are to avoid one point of attack and to increase availab...

With popularization and development of mobile commerce, the security of mobile commerce has drawn more and more attentions. Identity authentication is the first safety barrier, as communication security almost starts from its handshake process. Authentication protocol based on ciper technology is the safest method to realize identity authentication, and therefore identity authentication protoco...

With the development of network service technology such as grid computing, cloud computing, the cooperation among multiply domains is needed for these intelligent services that have the unlimited space and the unlimited speed. This paper proposes a new union authentication protocol of cross-domain that can ensure the security of resource access in different domains, where the register keys of m...

The fifth-generation mobile network (5G) will enable interconnectivity between the home (HN) and data (DN) whereby users with their user equipment (UE) be able to access services provided by external service providers (SP) seamlessly. SP rely on security assurances authentication protocols used. For 5G, primary UE HN has been defined specified Third Generation Partnership Project (3GPP) while s...

Status of This Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. Abstract This document defines an extensi...

Mobility management is the key feature of wireless network. When the mobile node roams from the home network to the foreign network, the foreign network access server usually does not have the security material of the mobile node, and can not authenticate the mobile node by itself. Thus the three-party authentication is used, and the foreign network access server consults the home authenticatio...

In recent years, Session Initiation Protocol (SIP) is more and more popular. However, there are many security problems in the Session Initiation Protocol. In 2005, Yang et al. [9] proposed a secure authentication scheme for Session Initiation Protocol. This authentication scheme is based on Diffie-Hellman [2] concept, so the computation cost of this authentication scheme is very high. In order ...
