This course covers the basic knowledge in understanding and using cryptography. The main focus is on definitions, theoretical foundations, and rigorous proofs of security, with some programming ...

Nathan Eddy works as an independent filmmaker and journalist based in Berlin, specializing in architecture, business technology and healthcare IT. He is a graduate of Northwestern University’s Medill ...

In the context of cryptography, a public key is an alphanumeric string that serves as an essential component of asymmetric encryption algorithms. It is typically derived from a private key, which must ...

Cryptography is an obscure discipline. Unless you're in big tech, a university or a research organization, you're unlikely to meet its practitioners. Even then, you might have to search to find them.

The original version of this story appeared in Quanta Magazine. For thousands of years, if you wanted to send a secret message, there was basically one way to do it. You’d scramble the message using a ...

Certificate-based authentication is a cryptographic technique that allows one computer to securely identify itself to another across a network connection, using a document called a public-key ...

An encryption method for transmitting data that uses key pairs, comprising one private and one public key. Public key cryptography is called "asymmetric encryption" because both keys are not equal. A ...

The security system that underlies the internet makes use of a curious fact: You can broadcast part of your encryption to make your information much more secure. When you purchase through links on our ...

The U.S. Department of Commerce's National Institute of Standards and Technology (NIST) has selected four quantum-resistant cryptographic algorithms for general encryption and digital signatures. NIST ...

IBM adds NIST’s new public-key encryption and digital signatures algorithms to defend against attacks by future quantum computers. While the need for it may be years away, IBM has added additional ...
