Cryptographic key exchange protocols are fundamental to secure digital communications, enabling two or more parties to establish a shared secret over an insecure channel. This field combines ...

Encrypted key exchange is a protocol, or set of rules, that allows two parties sharing a common password to communicate over an insecure network without exposing that password. The protocol was ...

Key exchange with unilateral authentication (short: unilateral key exchange) is an important primitive in practical security protocols; a prime example is the widely deployed TLS protocol, which ...

The researchers evaluated Signal alongside their own multi-stage key exchange security model. At least according to their analysis of the protocol’s cryptographic capabilities, Signal is secure.

Specifying key exchange protocols and the size of the prime numbers used by them is not typically something individual end-users are responsible for, though there are plenty of tools out there ...

ISAKMP is a key exchange framework that provides a security association and keys to be used by key exchange protocols such as IKE. Cisco adopted both the Oakley and ISAKMP protocols for use in ...

To send messages securely, two or more parties must first share, or exchange, a secret key, which is a string of genuinely random bits used to encrypt and decrypt messages. Quantum key distribution ...

The reason is that the cryptographic hash of the signature from the latter protocols includes a shared secret generated by the Diffie-Hellman key exchange.

A series of exploits have been found in the wild targeting Windows Internet Key Exchange (IKE) Protocol Extensions. According to a new advisory recently shared by security company Cyfirma with ...
