Rainbow Band Separation is Better than we Thought

June 10, 2020
Author(s)
Daniel Smith-Tone, Ray Perlner
Currently the National Institute of Standards and Technology (NIST) is engaged in a post- quantum standardization effort, analyzing numerous candidate schemes to provide security against the advancing threat of quantum computers. Among the candidates in

Combinatorial Rank Attacks Against the Rectangular Simple Matrix Encryption Scheme

April 10, 2020
Author(s)
Dustin Moody, Ray A. Perlner, Daniel C. Smith-Tone, Daniel C. Apon, Javier Verbel
In 2013, Tao et al. introduced the ABC Simple Matrix Scheme for Encryption, a multivariate public key encryption scheme. The scheme boasts great efficiency in encryption and decryption, though it suffers from very large public keys. It was quickly noted

Digital Identity Guidelines: Authentication and Lifecycle Management [includes updates as of 03-02- 2020]

March 2, 2020
Author(s)
Paul A. Grassi, James L. Fenton, Elaine M. Newton, Ray Perlner, Andrew Regenscheid, William E. Burr, Justin P. Richer, Naomi Lefkovitz, Jamie M. Danker, Yee-Yin Choong, Kristen K. Greene, Mary Theofanos
These guidelines provide technical requirements for federal agencies implementing digital identity services and are not intended to constrain the development or use of standards outside of this purpose. These guidelines focus on the authentication of

Status Report on the First Round of the NIST Post-Quantum Cryptography Standardization Process

January 31, 2019
Author(s)
Gorjan Alagic, Jacob M. Alperin-Sheriff, Daniel Apon, David Cooper, Quynh H. Dang, Carl Miller, Dustin Moody, Rene Peralta, Ray Perlner, Angela Robinson, Daniel Smith-Tone, Yi-Kai Liu
The National Institute of Standards and Technology is in the process of selecting one or more public-key cryptographic algorithms through a public competition-like process. The new public- key cryptography standards will specify one or more additional

HFERP -- A New Multivariate Encryption Scheme

April 1, 2018
Author(s)
Yashuhiko Ikematsu, Ray Perlner, Daniel Smith-Tone, Tsuyoshi Takagi, Jeremy Vates
In 2016, Yasuda et al.presented a new multivariate encryption technique based on the Square and Rainbow primitives and utilizing the plus modifier that they called SRP. The scheme achieved a smaller blow-up factor between the plaintext space and ciphertext

Improved Cryptanalysis of HFEv- via Projection

April 1, 2018
Author(s)
Jintai Ding, Ray Perlner, Albrecht R. Petzoldt, Daniel Smith-Tone
The HFEv- signature scheme is one of the most studied multivariate schemes and one of the major candidates for the upcoming standardization of post-quantum digital signature schemes. In this paper, we propose three new attack strategies against HFEv-, each

Thermodynamic Analysis of Classical and Quantum Search Algorithms

January 19, 2018
Author(s)
Ray A. Perlner, Yi-Kai Liu
We analyze the performance of classical and quantum search algorithms from a thermodynamic perspective, focusing on resources such as time, energy, and memory size. We consider two examples that are relevant to post-quantum cryptography: Grover's search

Total Break of the SRP Encryption Scheme

December 23, 2017
Author(s)
Ray A. Perlner, Albrecht R. Petzoldt, Daniel C. Smith-Tone
Multivariate Public Key Cryptography (MPKC) is one of the main candidates for secure communication in a post-quantum era. Recently, Yasuda and Sakurai proposed in [7] a new multivariate encryption scheme called SRP, which combines the Square encryption

SHA-3 Derived Functions: cSHAKE, KMAC, TupleHash and ParallelHash

December 22, 2016
Author(s)
John M. Kelsey, Shu-jen H. Chang, Ray Perlner
This Recommendation specifies four types of SHA-3-derived functions: cSHAKE, KMAC, TupleHash, and ParallelHash, each defined for a 128- and 256-bit security strength. cSHAKE is a customizable variant of the SHAKE function, as defined in FIPS 202. KMAC (for

Key Recovery Attack on Cubic Simple Matrix Encryption

August 11, 2016
Author(s)
Ray Perlner, Dustin Moody, Daniel Smith-Tone
In the last few years multivariate public key cryptography has experienced an infusion of new ideas for encryption. Among these new strategies is the ABC Simple Matrix family of encryption schemes which utilize the structure of a large matrix algebra to
