What’s the difference? Public key cryptography (asymmetric encryption) involves a pair of keys, while private key cryptography (symmetric encryption) uses a single shared key. Understanding the ...

Asymmetric encryption involves two keys – a public key and a private key – and is used to encrypt online communications, banking transactions, and other messages that involve multiple parties.

Researchers said their method of quantum encryption could lead to secure communication that is 'fundamentally beyond' an adversary's control.

Tuta has added a user-controlled key verification feature that brings heightened assurance to encrypted email and calendar exchanges. The feature allows senders and receivers to confirm the ...

Proponents believe hybrid encryption compensates for weaknesses in single post-quantum algorithms, but performance, complexity, and security concerns remain.

Chinese researchers have successfully used D-Wave's quantum annealing systems to break classic encryption, potentially accelerating the timeline for when quantum computers could pose a real threat ...
