Here, we propose a quantum asymmetric key cryptography scheme using Grover’s quantum search algorithm. In the proposed scheme, Alice generates a pair of public and private keys, keeps the private keys ...

The rapid proliferation of cloud computing enables users to access computing resources and storage space over the internet, but it also presents challenges in terms of security and privacy. Ensuring ...

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.

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 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 ...
