An efficient and secure RSA--like cryptosystem exploiting R\'edei rational functions over conics
, 2016 We define an isomorphism between the group of points of a conic and the set of integers modulo a prime equipped with a non-standard product. This product can be efficiently evaluated through the use of R\'edei rational functions.

Multi-secret Visual Cryptography Scheme with Tag Information
DEStech Transactions on Computer Science and Engineering, 2017 Since that traditional tagged visual cryptography scheme (TVCS) can only hide only one secret image, this paper presents a multi-secret visual cryptography scheme with tag information. By adopting the concept of random grids (RG) to construct the basic share images of secret images and the tag images, and then combined them in the form of probability ...

Side-Channel Attacks on Post-Quantum Signature Schemes based on Multivariate Quadratic Equations
Transactions on Cryptographic Hardware and Embedded Systems, 2018 In this paper, we investigate the security of Rainbow and Unbalanced Oil-and-Vinegar (UOV) signature schemes based on multivariate quadratic equations, which is one of the most promising alternatives for post-quantum signature schemes, against side ...
