Practical Lattice Basis Sampling Reduction
We propose a practical sampling reduction algorithm for lattice bases based on work by Schnorr [1] as well as two even more effective generalizations. We report the empirical behav...

Representing hard lattices with O(n log n) bits
We present a variant of the Ajtai-Dwork public-key cryptosystem where the size of the public-key is only O(n log n) bits and the encrypted text/clear text ratio is also O(n log n)...

Practical Power Analysis Attacks on Software Implementations of McEliece
The McEliece public-key cryptosystem is based on the fact that decoding unknown linear binary codes is an NP-complete problem. The interest on implementing post-quantum cryptograph...

Certificateless Authenticated Group Key Agreement Protocol for Dynamic Groups
A Group Key Agreement protocol is a process to establish a cryptographic key for a group of participants over an open network. In this paper, we propose a group key agreement(CAGKA...
