We show that the signer can abuse the disavowal protocol in the Jakobsson-Sako-
Impagliazzo designated-verifier signature scheme. In addition, we identify a new security …

This document describes an algorithm to generate one-time password values, based on
Hashed Message Authentication Code (HMAC). A security analysis of the algorithm is …

Network protocol stacks, in particular TCP/IP software implementations, are known for its
inability to scale well in general-purpose monolithic operating systems (OS) for SMP …

We investigate a general paradigm for constructing arbitrary-input-length (AIL) MACs from
fixed-input-length (FIL) MACs, define the waste as the relevant efficiency parameter of such …

We propose a new cryptographic construction called 3C, which works as a pseudorandom
function (PRF), message authentication code (MAC) and cryptographic hash function. The …

SecurID tokens are developed by SDTI/RSA Security to authenticate users to a corporate
computer infrastructure. In this paper we show the results of our analysis of the function …

Protocols that provide authentication and key distribution are mainly based on symmetric
and asymmetric ciphers. In recent years, some approaches have been introduced that are …
