Hash-and-Sign with Weak Hashing Made Secure
Abstract. Digital signatures are often proven to be secure in the random oracle model while hash functions deviate more and more from this idealization. Liskov proposed to model a ...

Provably secure ciphertext policy ABE
In ciphertext policy attribute-based encryption (CP-ABE), every secret key is associated with a set of attributes, and every ciphertext is associated with an access structure on a...

Security under key-dependent inputs
In this work we re-visit the question of building cryptographic primitives that remain secure even when queried on inputs that depend on the secret key. This was investigated by B...

Strongly-Secure Identity-Based Key Agreement and Anonymous Extension
Abstract. We study the provable security of identity-based (ID-based) key agreement protocols. Although several published protocols have been proven secure in the random oracle mod...
