Supervisory Host Model: A New Paradigm to Enhance the Security
and Power Management for Mobile Grid Environment
Abstract— Supervisory Host Model: A New Paradigm to Enhance the Security and Power Management for Mobile Grid Environment. Digital certificates and signatures provide protection in legally binding situations. Even though the digital certificates are used in banking and other legal binding process, they have got their own drawbacks which could be financial or technical. Financial being subscription for the service and technical being creation of platform that could accept all digital certificates and human errors. If the CA is subverted, then the security of the entire system is lost; resulting in a security breach of the entities that trust the compromised CA. Maintenance of CA in two or more levels requires more cost and time for authentication. < Final Year Projects 2016 > Moreover CA is a third party, so most of the business organizations, corporate, colleges and governments that use applications expect more security but doesn’t like to depend on a third party. This paper proposes a new concept called Supervisory Host (SH) which is a static node that takes care of certificate generation and distribution. The advantages of Supervisory Host are simple registration process, reduced level of key exchange process and improved authentication process between two parties. SH is maintained independently for any particular application, the trust level is high and authentication process can be improved with the help of ECDSA (Elliptic Curve Cryptography Digital Signature Algorithm) algorithm.
