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 ...

Microsoft is killing off an obsolete and vulnerable encryption cipher that Windows has supported by default for 26 years following more than a decade of devastating hacks that exploited it and ...

Revenue missed expectations at $72.0M versus $79.1M forecast, but adjusted earnings per share beat handily at $0.10 against a loss estimate of negative $0.02. By the time the market closed, shares of ...

Two years ago, researchers in the Netherlands discovered an intentional backdoor in an encryption algorithm baked into radios used by critical infrastructure–as well as police, intelligence agencies, ...

Quantum computers could crack a common data encryption technique once they have a million qubits, or quantum bits. While this is still well beyond the capabilities of existing quantum computers, this ...

Ofer A. Lidsky is an entrepreneur with over 30 years of experience and is the founder and CEO of Excellent Brain. In today’s digital age, data encryption is vital for protecting sensitive information.

There’s little doubt that some of the most important pillars of modern cryptography will tumble spectacularly once quantum computing, now in its infancy, matures sufficiently. Some experts say that ...

The National Institute of Standards and Technology announced a new series of digital signature algorithms ready for the agency’s post-quantum cryptographic standardization process, following the ...
