Cryptanalysis of Certificateless Signcryption Schemes and an Efficient Construction without Pairing
Abstract. Certificateless cryptography introduced by Al-Riyami and Paterson eliminates the key escrow problem inherent in identity based cryptosystems. Even though building practic...

Threshold Public-Key Encryption with Adaptive Security and Short Ciphertexts
Threshold public-key encryption (TPKE) allows a set of users to decrypt a ciphertext if a given threshold of authorized users cooperate. Existing TPKE schemes suffer from either lo...

Authenticated Key Agreement with Key Re-use in the Short Authenticated Strings Model
Serge Vaudenay [20] introduced a notion of Message Authentication (MA) protocols in the Short Authenticated String (SAS) model. A SAS-MA protocol authenticates arbitrarily long mes...
