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 ...

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 advanced ...

In my previous article/video how does encryption work? I wrote about the principles of encryption starting with the Caesar cipher and following the development of cryptography through to the modern ...

Today we’re going to talk about how to keep information secret, and this isn’t a new goal. We’re going to walk you through some common encryption techniques such as the Advanced Encryption Standard ...

The concept of cryptography touches our lives many times per day, and that’s probably a conservative estimate. We have a pretty good idea of how it works, having dealt with public-key cryptography for ...

Scientists in China managed to exchange a crypto key at a distance of over 1,000 kilometers, could this lead to hackerproof cryptography? Scientists in China were able to exchange an encryption key at ...

A new type of optical fiber filled with nothing but thin air has been found to be particularly effective for carrying out quantum key distribution (QKD), a security protocol that is in principle ...
