Abstract—It is challenging to provide authentication to timecritical multicast data, where low end-to-end delay is of crucial importance. Consequently, it requires not only effi...
In this paper, a new block-based image-dependent watermarking technique is proposed. The proposed technique utilizes the correlation coefficient statistic to produce a short and un...
—The pervasive distribution of digital images triggers an emergent need of authenticating degraded images by lossy compression and transmission. This paper proposes a robust cont...
Abstract--We consider the use of threshold signatures in adhoc and dynamic groups such as MANETs ("mobile ad-hoc networks"). We first show that known threshold RSA signat...

Abstract. This paper presents identity based serial and parallel multisignature schemes using bilinear pairings. Our serial multisignature scheme requires a forced verification at ...
