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 ...

Security firm Mandiant has released a database that allows any administrative password protected by Microsoft’s NTLM.v1 hash algorithm to be hacked in an attempt to nudge users who continue using the ...

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, ...

Two former Google DeepMind researchers who worked on the company’s Nobel Prize-winning AlphaFold protein structure prediction AI as well as its AlphaEvolve code generation system have launched a new ...

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 ...

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 ...

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 ...

The move toward multi-die assemblies and the increasing value of sensor data at the edge are beginning to focus attention and raise questions about security in analog circuits. In most SoC designs ...
