Certificateless generalized signcryption scheme in the standard model
In 2010,Liu,et al.proposed a certificateless signcryption scheme in the standard model,but many analyses revealed that Liu's scheme was insecure in fact.To overcome the disadvantages,the scheme was improved and a certificateless generalized signcryption ...

Recent proposals by Mahmood et al., Braeken et al., and Chaudhry et al. aimed at establishing secure communication in AMI, asserting their methods fulfil the requisite security criteria. This paper, however, reveals that each of these proposals exhibits security vulnerabilities and lacks sufficient features for deployment.

On the Security of Diffie-Hellman Bits
Boneh and Venkatesan have recently proposed a polynomial time algorithm for recovering a “hidden” element α of a finite field \(\mathbb{F}_p \) of p elements from rather short strings of the most significant bits of the remainder modulo p of αt for several values of t selected uniformly at random from \(\mathbb{F}_p^* \) We use some recent bounds of ...
