Herding, Second Preimage, and Trojan Message Attacks Beyond Merkle-Damgaard

November 3, 2009
Author(s)
Elena Andreeva, Charles Bouillaguet , Orr Dunkelman, John M. Kelsey
In this paper we present new attack techniques to analyze the structure of hash functions that are not based on the classical Merkle-Damgaard construction. We extend the herding attack to concatenated hashes, and to certain hash functions that process each

This paper provides definitions for some desirable properties of voting systems, including auditability, ballot secrecy, incoercibility, usability and accessibility. In the context of these desirable properties, it defines the class of end-to-end

Recommendation for Digital Signature Timeliness

September 23, 2009
Author(s)
Elaine B. Barker
Establishing the time when a digital signature was generated is often a critical consideration. A signed message that includes the (purported) signing time provides no assurance that the private key was used to sign the message at that time unless the
