Quantum computing represents a major threat to encryption, and the inflection point may be less than five years away.

Algorithms for encrypting computer data come in two main varieties: symmetric and asymmetric. Each encryption type has inherent strengths and weaknesses. Symmetric algorithms convert plain-text data ...

Microsoft recently confirmed that it is finally deprecating RC4, the encryption method used by the Kerberos authentication protocol for the past three decades. Developed by mathematician ...

A recent, yet to be proven paper claiming to have found a way to "destroy the RSA cryptosystem" has cryptographers asking what might replace it. What if a big crack appeared overnight in the ...

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, ...
