A relatively new ransomware family is using a novel approach to hype the strength of the encryption used to scramble files—making, or at least claiming, that it is protected against attacks by quantum ...

Before RSA, secure communication required sharing secret keys, an impossible task at global scale. This is the story of how a trapdoor hidden inside number theory became the invisible infrastructure ...

Scientists have unveiled a new approach to ultra-secure communication that could make quantum encryption simpler and more efficient than ever before. By harnessing a 19th-century optics phenomenon ...

For decades, the quantum threat to RSA and ECC encryption has been tied to Shor’s algorithm and the assumption that we would need million-qubit quantum computers to make it practical. A newly ...

Abstract: To enhance the secure storage and real-time transmission of vehicle images on highways, this study proposes a fast parallel multi-image encryption scheme. First, a dual-memristor exponential ...

Abstract: Currently, both pixel-level and bit-level image encryption algorithms demonstrate excellent visual performance. However, most high-security algorithms usually involve complex encryption ...

Microsoft provided the FBI with the recovery keys to unlock encrypted data on the hard drives of three laptops as part of a federal investigation, Forbes reported on Friday. Many modern Windows ...

About time: Microsoft introduced support for the RC4 stream cipher in Windows 2000 as the default authentication algorithm for the Active Directory services. The system has been insecure for even ...
