The role-based access control (RBAC) model has proven to be cost effective to reduce the complexity and costs of access permission management. To maximize the advantages offered...

It is envisaged that the application of the multilevel security (MLS) scheme will enhance exibility and e ectiveness of authorization policies in shared enterprise databases and w...
Designers of cryptographic systems are at a disadvantage to most other engineers, in that information on how their systems fail is hard to get: their major users have traditionall...
Given an arbitrary intruder deduction capability, modeled as an inference system S and a protocol, we show how to compute an inference system bS such that the security problem for ...
We present a robust multiparty computation protocol. The protocol is for the cryptographic model with open channels and a polytime adversary, and allows n parties to actively secur...
