Providers are testing a quantum-safe version of HTTPS that shrinks certificates to a tenth their previous size, decreasing ...

Birthday attacks exploit the collision probability of hash functions. Collision resistance requires sufficiently large hash outputs. Modern blockchains use 256-bit hashes to mitigate collision risks.

The joint venture acquiring TikTok’s US assets has been formally established and has announced its leadership team, according to the company, one day before the deadline set by President Donald Trump ...

I would like to ask whether it is possible in OP-TEE to use different algorithms for the main hash and the MGF1 hash in RSA OAEP. I would like to decrypt data using OP-TEE when the data was encrypted ...

Cryptography secures communication in banking, messaging, and blockchain. Good algorithms (AES, RSA, ECC, SHA-2/3, ChaCha20) are secure, efficient, and widely trusted. Bad algorithms (DES, MD5, SHA-1, ...

Oracle (NYSE:ORCL) shares were up 0.9% in premarket trading on optimism over the software company’s potential role in a TikTok deal. The technology firm would rebuild and secure a new U.S. version of ...

Quantum computing promises significant breakthroughs in medicine, material sciences, and beyond. As technology advances, our approach to cybersecurity must also evolve. The emergence of quantum ...

The National Institute of Standards and Technology has announced a new cryptography standard that's available for immediate use. The standard is designed to assure the protection of authenticated ...

The hash rate measures the computational power of the Bitcoin blockchain network and other PoW cryptocurrencies, determined by the number of guesses made per second. The significance of hash rate in a ...

Blake3 is not listed as secure hashing algorithm in NIST SP 800-140Cr2 and therefore not FIPS 140 compliant. It's not clear if the choice and properties of the hashing algorithm is security relevant.
