Abstract: In response to security issues associated with palm vein images during the recognition process, as well as the small key space and security concerns of chaotic systems, this paper proposes ...

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, ...
