Abstract The LLL algorithm aims at finding a “reduced” basis of a Euclidean lattice. The LLL algorithm plays a primary role in many areas of mathematics and computer science. ...
Denoting by P = [k]G the elliptic-curve double-and-add multiplication of a public base point G by a secret k, we show that allowing an adversary access to the projective representa...
In certain reliable group-oriented and multicast applications, a source needs to securely verify whether all (and if not all, which) intended receivers have received a message. How...

Digital signature authentication scheme provides secure communication between two users. Digital signatures guarantee end-to-end message integrity and authentication information a...
Blind signatures (BS), introduced by Chaum, have become a cornerstone in privacy-oriented cryptography. Using hard lattice problems, such as the shortest vector problem, as the bas...
