Security Thread Analysis & Solution for NGN (Next Generation Network)
Essential feature of New Generation Networks (NGN) is the availability of many new services offered by several different players. Different applications and services have their own authentication method and use different credentials, more reliable, flexible and easy-to-use methods are needed. In this paper, the authors concern about different security vulnerabilities found in existing system and gives possible solutions to eliminate them. These vulnerabilities are the possibilities to forge key messages, unauthenticated messages and Man In the Middle attack. They proposed a secure key generation process, random number and function generation process to eliminate these vulnerabilities.
