Why upgrade if PQ signatures are not yet proven?The dirty secret of efforts to upgrade blockchains to post-quantum ...

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.

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, ...

Technology company Oracle will provide security for the new TikTok entity in the United States, following the President Trump-backed deal to allow the social media company to keep operating in the U.S ...

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 ...

Algorithms, examples and tests for denoising, deblurring, zooming, dequantization and compressive imaging with total variation (TV) and second-order total generalized variation (TGV) regularization.

Crypto thrives on cutting-edge technology, but quantum computing could challenge the cryptographic foundations that keep Bitcoin secure. As quantum advancements accelerate, concerns about risks to ...

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.

Abstract: A computer is recognized as a universal device that can simulate any other computational device, though it may take time. Cryptography is becoming more important as the Internet becomes more ...
