Pham. Privilege Delegation and Revocation for Distributed Computing PRIVILEGE DELEGATION AND REVOCATION FOR DISTRIBUTED PERVASIVE COMPUTING ENVIRONMENTS

ABSTRACT: This paper looks at the problem of privilege delegation and revocation in distributed pervasive computing environments. In this paper, the relationship between the privilege delegation and revocation will be discussed as well as how to deploy them on distributed systems. There will be a signature based schemes to achieve privilege delegation with different trust assumptions. The scheme operates by using either public key or secret key based cryptography. Then the issues of revocation of delegations and proposal some schemes to achieve this. Finally, the transitivity of trust in related with privilege delegation and implicated trust assumptions will be briefly mentioned in the conclusion
