Cryptographic role-based security mechanisms based on role-key hierarchy
Even though role-based access control (RBAC) can tremendously help us minimize the complexity in administering users, it is still needed to realize the notion of roles at the reso...

A Nonuniform Algorithm for the Hidden Number Problem in Subgroups
Boneh and Venkatesan have proposed a polynomial time algorithm in a non-uniform model for recovering a ”hidden” element α ∈ IFp, where p is prime, from very short strings of...
