-Biometric authentication system are used prevalently for its template security, retract ability and privacy. The Authentication process is reinforced by biometric cryptosystem. We propose a demonstrable secure and blind biometric authentication protocol which discloses only identity and not any other information to both client and server. To reduce the computational cost and enhance security w...

A mobile ad hoc network (MANET) is formed with wireless mobile devices (nodes) without the need for existing network infrastructure. Security design in MANET (Mobile advoc network) is complicated because of its features including lack of infrastructure, mobility of nodes; dynamic topology and open wireless medium .Due to this MANET suffer from many security vulnerability. To enhance the securit...

The evolutionary effect of social network analysis has feasibly enabled the security agencies to include the approach for estimating terrorist networks. The approach in this sense named as Terrorist Network Mining, has helped in successfully achieving the terrorist network behaviour on web along with destabilization of network using hierarchy of algorithms. However these algorithm results in fr...

The Domain Name System is critical for the proper operation of applications on the Internet. Unfortunately, the DNS has a number of significant security weaknesses that can result in the compromise of web sites, email messages login sessions. Additionally, these weaknesses have been used as the basis for man-in-themiddle attacks on what are considered secure network protocols. This paper provid...

Application protection is a valuable security layer to protect against a number of application layer security threats which is usually not protected by a typical network layer intrusion detection system. The hackers will attack the Web Application using the methods like structured Query Language (SQL) Injection, Cross Site Scripting (XSS), Command Injection, cookie poisoning, etc. These problem...

Critical Infrastructure Protection is one of the main challenges of last years. Security Information and Event Management (SIEM) systems are widely used for coping with this challenge. However, they currently present several limitations that have to be overcome. In this paper we propose an enhanced SIEM system in which we have introduced novel components to i) enable multiple layer data analysi...

Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile hosts forming a temporary network without the aid of any stand-alone infrastructure or centralized administration. Most of the proposed MANET protocols do not address security issues. In MANETs routing algorithm is necessary to find specific routes between source and destination. The primary goal of any ad-hoc network routing prot...

We propose in this paper a computationally efficient security scheme for identifying network members in wireless sensor networks. The authentication process is done by first identifying the base station as being the authentic one with the use of fingerprinting information. Once the base station is authenticated, the others members of the network can then be authenticated by the base station. Th...

Various network applications require sending data onto one or many members, maintaining security in the large groups is one of the major obstacles for controlling access. Unfortunately, IP multicast is not providing any security over the group communication. Group key management is a fundamental mechanism for secured multicast. This paper presents relevant group key management protocols. Then, ...

Personal Networks (PN) are future communication systems that combine wireless and infrastructure based networks to provide users a variety of services anywhere and anytime. PNs introduce new design challenges due to the heterogeneity of the involved technologies, the need for self-organization, the dynamics of the system composition, the application-driven nature, the co-operation with infrastr...
