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

Abstract: Cryptographic hash functions are essential for securing data integrity in systems such as digital signatures, blockchain networks, and secure communication protocols. Among the widely ...

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 ...

Richard Escobedo covers economic policy at CBS News and is a coordinating producer at Face the Nation with Margaret Brennan. He joined CBS in 2018 and is a graduate of Texas Christian University in ...

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 ...

In this tutorial, we explore how to secure AI agents in practical, hands-on ways using Python. We focus on building an intelligent yet responsible agent that adheres to safety rules when interacting ...

Abstract: In this paper, we propose a provable secured hash function based on the block cipher, called BM, with 512-bits hash length. The proposed hash algorithm uses the Alpha-DBL compression ...

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, ...
