Differential Properties of the HFE Cryptosystem

October 1, 2014

Author(s)

Taylor Daniels, Daniel Smith-Tone

Multivariate Public Key Cryptography (MPKC) has been put forth as a possible post-quantum family of cryptographic schemes. These schemes lack provable security in the reduction theoretic sense, and so their security against yet undiscovered attacks remains

A Classification of Differential Invariants for Multivariate Post-Quantum Cryptosystems

June 21, 2013

Author(s)

Ray A. Perlner, Daniel C. Smith-Tone

Multivariate Public Key Cryptography (MPKC) has become one of a few options for security in the quantum model of computing. Though a few multivariate systems have resisted years of effort from the cryptanalytic community, many such systems have fallen to a

The TriTon Transformation

August 27, 2012

Author(s)

Daniel C. Smith-Tone

Many new systems have been proposed which hide an easily invertible multivariate quadratic map in a larger structure by adding more variables and introducing some mixing of a random component to the structured system. While many systems which have been

Improved Indifferentiability Security Bound for the JH Mode

March 22, 2012

Author(s)

Dustin Moody, Souradyuti Paul, Daniel C. Smith-Tone

The JH hash function is one of the five fi nalists of the ongoing NIST SHA3 hash function competition. Despite several earlier attempts, and years of analysis, the indi fferentiability security bound of the JH mode has so far remained remarkably low, only

On the Differential Security of Multivariate Public Key Cryptosystems

November 29, 2011

Author(s)

Daniel C. Smith-Tone

Since the discovery of an algorithm for factoring and computing discrete logarithms in polynomial time on a quantum computer, the cryptographic community has been searching for an alternative for security in the approaching post-quantum world. One

Clean Agent Performance on Fires Exposed to an External Energy Source.

November 2, 1998

Author(s)

Kenneth D. Steckler, William L. Grosshandler, Daniel C. Smith-Tone, P Rivers

Work carried out over the last several years has shown that there can be a significant increase in the amount of agent required to extinguish and to prevent re-ignition of fires that are exposed to a continuous, external, energy source. This has
