This paper introduces Hidden Identity-based Signatures (Hidden-IBS), a type of digital signatures that provide mediated signer-anonymity on top of Shamir’s Identity-based signat...
In this paper, we present a secure group key management scheme for hierarchical mobile ad-hoc networks. Our approach aims to improve both scalability and survivability of group ke...
Group encryption (GE) schemes, introduced at Asiacrypt’07, are an encryption analogue of group signatures with a number of interesting applications. They allow a sender to encryp...
Abstract - A robust method for symbol recognition is presented that utilizes a compact signature based on a modified Hough Transform (HT) and knowledge-based hierarchical neural ne...
Currently, there are relatively few instances of "hash-and-sign" signatures in the standard model. Moreover, most current instances rely on strong and less studied assum...
