Message privacy, increasingly important to Bitcoiners, can be achieved with public and private key cryptography. As a Bitcoiner, you’re going to need a secure way to communicate privately, without ...

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 ...

Public key encryption with equality test (PKEET) represents a significant advance in cryptographic research. This technology allows a designated tester to determine whether two independently generated ...

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 ...

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 special rule, known only to you and your intended audience.

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 ...

Public-key cryptography (PKC, or asymmetric cryptography) had a revolutionary effect on the theory of cryptography. PKC’s use of pure mathematical hard problems led to a study of academic, theoretical ...

Google has significantly shortened its readiness deadline for Q Day, the point when existing quantum computers can break public-key cryptography algorithms.

As a Bitcoiner, you’re going to need a secure way to communicate privately, without relying on a company to encrypt your data for you. For example, freely available methods with end-to-end encryption ...
