Generalized signcryption which proposed by Han is a new cryptographic primitive which can work as an encryption scheme, a signature scheme or a signcryption scheme [5]. However,the...
In this paper we introduce the idea of using Computer Vision techniques for improving and enhancing watermarking capabilities. Specifically, we incorporate Geometric Hashing techn...
We present schemes for hardeningimage watermarks against adversarial jamming. Our techniques improve upon standard correlation- and spread spectrum-based methods, and withstand va...
Abstract. A side-channel analysis of a cryptographic algorithm generally concentrates on the encryption or decryption phases, rarely on the key generation phase. In this paper, we ...
The diversity of methods for fast collision search in SHA-1 and similar hash functions makes a comparison of them difficult. The literature is at times very vague on this issue, wh...
