Abstract: This paper introduces an enhanced lightweight image encryption method, combining a stream cipher and the Secure Hash Algorithm (SHA). The primary focus is developing a robust and efficient ...

Quantum computing won’t break Bitcoin in 2026, but attackers are already preparing. Here’s how crypto is moving toward post-quantum security, and how ready it is.

The system employs HMAC-SHA256 (Hash-based Message Authentication Code using SHA-256) for license integrity verification. SHA-256 refers to the Secure Hash Algorithm producing 256-bit hash values (see ...

Solana and Aptos developers started testing new “quantum-safe” security this week, aiming to protect their blockchains from future attacks by powerful quantum computers. SOL USD traded around $126 ...

Charles Edwards warns that quantum computing could depress Bitcoin price below $50,000 if the network does not address quantum issues. His view is provocative but ...

Abstract: The explosion of IoT edge devices has made data security, authenticity, and integrity increasingly difficult to guarantee in settings with limited resources. Low-power Internet of Things ...

Tokenization is a crucial technology for ensuring the security and privacy of patient data in clinical research, pharmacovigilance, and drug safety monitoring. As healthcare increasingly integrates ...

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 ...
