Two-Phase Device Authentication Scheme for Request-Response Computing

Request-response computing is a model of communications in which a client requests for service and the server responds with response. It is a model that is most widely used in modern day computing and is more reliable and resource aware. Security is a prime concern in this model of computing, where malicious entities may gain access to crucial data and resources illegitimately. An efficient authentication mechanism may establish a secure communication channel between client and server and avoid illegitimate access of resources. Here, we propose a two-phase authentication mechanism using address binding for securing the communications between clients and server. The first phase of binding is done using cryptographically generated address (CGA) and for the second phase, we have designed a novel Mathematically Generated Address (MGA), in which IPv6 address are masked using mathematical operations and it is lightweight and secure. The proposed mechanism is secure and efficient and is verified in security analysis and performance evaluation as well. The proposed mechanism is evaluated for security and performance and its analysis has found that the proposed mechanism works efficiently in terms of security and time in comparison to the existing mechanism.
