Near field Communication having a capability to secured money transaction thus it requires heavy security during card emulation mode comm. INFCP provides a user based security, Improved Near Field Communication Protocol makes a NFC device more advance and secure from any false user from the existing model. This security is very tactical because it’s totally depends upon user functionality his/h...

Today, people benefit various services through networks. However, due to the open environment of communications, networks are vulnerable to variety of security risks. Remote access capability is one of the critical functions for network systems. The remote user authentication scheme provides the server a convenient way to authenticate users before they are allowed to access database and obtain ...

It is well known that cyber security plays a critical role in ensuring functionality and reliability of increasingly ubiquitous communication systems and critical infrastructures. Compared with the traditional attacks that target individual users, protocols, or components in the complicated systems, the emerging attacks can 1) exploit collaboration among multiple users or network nodes, 2) expl...

Password security is essential for user authentication on small networking system as well large networking system. Till today many researchers introduced various methods to protect passwords on network. Passwords are prone to various types of attacks like brute force attack, password reuse attack, password stealing attack, password cracking attack, etc. This paper gives review on different meth...

A simulation infrastructure for wireless network emulation based on User Mode Linux and on the virtualisation of the hostap driver is proposed. The interconnection of these components is first described and the architecture of the resulting network emulator is explained. Two practical applications are then detailed : the testing of an implementation of the AODV routing protocol in a highly real...

To ensure secure transmission of data and to authenticate remote user while accessing server resources, smart card based remote user authentication schemes have been widely adopted. In 2004, Das et al proposed first of its kind of protocol for remote user authentication with smart cards using Dynamic Id to protect user anonymity. In 2005, Chien et al pointed out that Das et al scheme failed to ...

In 2013, Qu demonstrated that Awasthi et al.’s remote user authentication scheme is vulnerable to smart card loss attack, off-line password guessing attack and does not preserve anonymity of user. However, this paper points out that Qu’s scheme is still vulnerable to off-line password guessing attack and smart card loss attack, and also does not preserve anonymity of a user unlike its claim. Fo...

In 2010, Yeh et al. proposed two robust remote user authentication schemes using smart cards; their claims were such that their schemes defended against ID-theft attacks, reply attacks, undetectable on-line password guessing attacks, off-line password guessing attacks, user impersonation attack, server counterfeit attack and man-in-the-middle attack. In this paper, we show that Yeh et al.’s sch...

To provide secure authentication for wireless sensor networks (WSNs), recently Jiang et al. proposed an efficient two-factor user authentication scheme with unlinkability. They argued that the scheme provides resilience of privileged insider attack, stolen-verifier attack, password guessing attack, weak stolen smart card attack, replay attack, forgery attack, identity guessing attack and tracki...

We introduce a Semantic Identification Attack, in which an adversary uses semantic signals about the pages visited in one browsing session to identify other browsing sessions launched by the same user. This attack allows an adversary to determine if two browsing sessions originate from the same user regardless of any measures taken by the user to disguise their browser or network. We use the MS...
