Fine-grained forward-secure signature schemes without random oracles
We propose the concept of fine-grained forward-secure signature schemes. Such signature schemes not only provide non-repudiation w.r.t. past time periods the way ordinary forward-...

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...

Public-Key Cryptography from New Multivariate Quadratic Assumptions
In this work, we study a new multivariate quadratic (MQ) assumption that can be used to construct public-key encryption schemes. In particular, we research in the following two di...
