After a multi-year competition, the U.S. National Institute of Standards and Technology (NIST) selected a suite of algorithms for standardization. For key exchange, the primary choice is the ...

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 ...

The Diffie-Hellman algorithm was a stunning breakthrough in cryptography that showed cryptographic keys could be securely exchanged in plain sight. Here’s how it works. Whitfield Diffie and Martin ...

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 ...

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 ...

Every time you send a text, pay for groceries with your phone, or use your health site, you are relying on encryption.

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 ...

Today, PKC forms the foundation for e-commerce, allowing more than US$1 trillion per day in foreign exchange transactions in North America alone. 10 This technology also allows electronic banking, ...

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 ...

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 ...
