Fine-Grained Two Factor Access Control for Web Based Cloud Computing Services

Abstract

Mediated cryptography was first familiar as a procedure with allow provoke refusal of open keys. The key idea of mediated cryptography is to use an on-line mediator for each trade. This on-line center individual is implied a SEM (Security Mediator) since it gives a control of security capacities. In case the SEM does not team up then no trades with individuals when all is said in done key are possible any more. The general idea of key-protected security was to store whole deal enters in a physically-secure anyway computationally-obliged device.
