RTL-PSC: Automated Power Side-Channel Leakage Assessment at Register-Transfer Level

July 11, 2019
Author(s)
Miao (Tony) He, Jungmin Park, Adib Nahiyan, Apostol Vassilev, Yier Jin, Mark Tehranipoor
Power side-channel attacks (SCAs) have become a major concern to the security community due to their non- invasive feature, low-cost, and effectiveness in extracting secret information from hardware implementation of cryto algorithms. Therefore, it is

Author(s)
Luis Brandao, Michael S. Davidson, Nicky W. Mouha, Apostol T. Vassilev
This bulletin summarizes the information found in NISTIR 8214: Threshold Schemes for Cryptographic Primitives. NIST is interested in promoting the security of implementations of cryptographic primitives. This security depends not only on the theoretical

Security Requirements for Cryptographic Modules

March 22, 2019
Author(s)
National Institute of Standards and Technology (NIST), Michael J. Cooper, Kim B. Schaffer
The selective application of technological and related procedural safeguards is an important responsibility of every federal organization in providing adequate security in its computer and telecommunication systems. This standard is applicable to all

Recommendation for Pair-Wise Key Establishment Using Integer Factorization Cryptography

March 21, 2019
Author(s)
Elaine B. Barker, Lidong Chen, Allen L. Roginsky, Richard Davis, Scott Simon
This Recommendation specifies key-establishment schemes using integer factorization cryptography (in particular, RSA). Both key-agreement and key transport schemes are specified for pairs of entities, and methods for key confirmation are included to

Transitioning the Use of Cryptographic Algorithms and Key Lengths

March 21, 2019
Author(s)
Elaine B. Barker, Allen L. Roginsky
The National Institute of Standards and Technology (NIST) provides cryptographic key management guidance for defining and implementing appropriate key management procedures, using algorithms that adequately protect sensitive information, and planning ahead

Threshold Schemes for Cryptographic Primitives

March 1, 2019
Author(s)
Luis T. A. N. Brandao, Nicky W. Mouha, Apostol T. Vassilev
The Computer Security Division at the National Institute of Standards and Technology is interested in promoting the security of implementations of cryptographic primitives. This security depends not only on the theoretical properties of the primitives but

Extracting Linearization Equations from Noisy Sources

February 15, 2019
Author(s)
Daniel C. Smith-Tone
This note was originally written under the name "On the Security of HMFEv" and was submitted to PQCrypto 2018. The author was informed by the referees of his oversight of an eprint work of the same name by Hashimoto, see eprint article /2017/689/, that

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

Automated Cryptographic Validation (ACV) Testing

September 24, 2018
Author(s)
Apostol T. Vassilev, Larry Feldman, Gregory A. Witte
This bulletin summarizes the NIST Automated Cryptographic Validation (ACV) Testing project. NIST selects and standardizes cryptographic algorithms as NIST-approved for use within the U.S. Federal Government. The Computer Security Division specifies the

The Economic Impacts of the Advanced Encryption Standard, 1996-2017

September 7, 2018
Author(s)
David P. Leech, Stacey Ferris, John T. Scott
Cryptography is a branch of applied mathematics concerned with developing complex algorithms for scrambling information ("plaintext") into an indecipherable version of that information ("ciphertext") and back to plaintext. The basics of cryptography as it

Pseudorandom Quantum States

August 19, 2018
Author(s)
Yi-Kai Liu, Zhengfeng Ji, Fang Song
We propose the concept of pseudorandom quantum states, which appear random to any quantum polynomial-time adversary. It offers a computational approximation to perfectly random quantum states (analogous to cryptographic pseudorandom generators), as opposed

Finding Bugs in Cryptographic Hash Function Implementations

July 6, 2018
Author(s)
Nicky W. Mouha, Mohammad Raunak, David R. Kuhn, Raghu N. Kacker
Cryptographic hash function implementations can be particularly difficult to test, and bugs can remain unnoticed for a very long time. We revisit the NIST SHA-3 hash function competition, and apply a new testing strategy to all available reference

Author(s)
Hildegard Ferraiolo, Ketan L. Mehta, Nabil Ghadiali, Jason Mohler, Vincent Johnson, Steven Brady
This recommendation provides a technical guideline to use Personal Identity Verification (PIV) Cards in facility access; enabling federal agencies to operate as government-wide interoperable enterprises. These guidelines cover the risk-based strategy to

Protecting Software Integrity Through Code Signing
