Amongst provably secure signature schemes, two distinct classes are of particular interest: the ones with tight reduction (e.g., RSA-PSS), and those which support the use of coupon...
Ad hoc networks are dynamic networks formed "on the fly" by a set of nodes. Achieving secure routing in such networks is a big challenge. Asymmetric signature schemes pr...

A new concept of society-oriented designated confirmer signatures (SDCS) is introduced in this paper. SDCS is well suited to applications where the capability of the signer and th...
First we revisit three - BGLS, MBGLS and GZZ verifiably encrypted signature schemes [2, 3, 6]. We find that they are all not strong unforgeable.We remark that the notion of existen...
Abstract. We present a related family of authentication and digital signature protocols based on symmetric cryptographic primitives which perform substantially better than previous...
