Semantic security for the McEliece cryptosystem without random oracles
In this paper, we formally prove that padding the plaintext with a random bit-string provides the semantic security against chosen plaintext attack (IND-CPA) for the McEliece (and ...

A Provable-Security Treatment of the Key-Wrap Problem
Abstract. We give a provable-security treatment for the key-wrap problem, providing definitions, constructions, and proofs. We suggest that key-wrap's goal is security in the ...

Efficient Proving for Practical Distributed Access-Control Systems
We present a new technique for generating a formal proof that an access request satisfies accesscontrol policy, for use in logic-based access-control frameworks. Our approach is t...
