The U.S. National Institute of Standards and Technology, an agency within the Department of Commerce, announced Thursday that it's formally retiring the SHA-1 cryptographic algorithm. SHA-1, short for Secure Hash Algorithm 1, is a 27-year-old hash function used in cryptography and has since been deemed broken owing to the risk of collision attacks.
As soon as possible isn't necessarily all that soon: NIST says you should be rid of SHA-1 from your software and systems by December 31, 2030. SHA-1 is among seven hash algorithms approved for use in the Federal Information Processing Standard 180-4.
The SHA-1 algorithm, one of the first widely used methods of protecting electronic information, has reached the end of its useful life, according to security experts at the National Institute of Standards and Technology (NIST). The agency is now recommending that IT professionals replace SHA-1, in the limited situations where it is still used, with newer algorithms that are more secure. “We recommend that anyone relying on SHA-1 for security migrate to SHA-2 or SHA-3 as soon as possible,” said NIST computer scientist Chris Celi.
Ransomware attacks keep increasing in volume and impact largely due to organizations' weak security controls. Mid-market companies are targeted as they possess a significant amount of valuable...
Current quantum computers are still toy prototypes, and the engineering advances required to build a functionally useful quantum computer are somewhere between a few years away and impossible. The idea is to standardize on both a public-key encryption and digital signature algorithm that is resistant to quantum computing, well before anyone builds a useful quantum computer.
IBM has started offering quantum-resistant crypto - using the quantum-resistant crypto recommended by the US National Institute of Standards and Technology. China is felt to be stealing data today, safe in the knowledge its future quantum computers will be able to decrypt it in the near future.
The U.S. Department of Commerce's National Institute of Standards and Technology has chosen the first group of quantum-resistant encryption tools, designed to withstand the assault of a future quantum computer, which could potentially crack the security used to protect privacy in the digital systems we rely on every day - such as online banking and email software. This Help Net Security video covers the highlights of four encryption algorithms selected by NIST..
The U.S. Department of Commerce's National Institute of Standards and Technology has chosen the first set of quantum-resistant encryption algorithms that are designed to "Withstand the assault of a future quantum computer." Quantum computers, should they mature enough, pose a huge impact on the current public-key algorithms, since what could take, say, trillions of years on a conventional computer to find the right key to decode a message could merely take days or hours, rendering them susceptible to brute-force attacks.
The Department of Commerce's National Institute of Standards and Technology has chosen four encryption algorithms that are designed to withstand the hacking of a future quantum computer and protect digital information. NIST said all four of the algorithms were created by experts collaborating from multiple countries and institutions.
NIST's post-quantum computing cryptography standard process is entering its final phases. For general encryption, used when we access secure websites, NIST has selected the CRYSTALS-Kyber algorithm.
