Post-quantum identity-based encryption has been solved from isogeny-based assumptions for the first time, as researchers from ...

I have a long and tattered history with cryptography. Ever since I learned about Bob and Alice I was smitten. I knew it was important because cryptographic algorithms could be used to protect ...

Graduate student Seyoon Ragavan led the work alongside senior author Vinod Vaikuntanathan, a computer science professor at ...

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 ...

A private key, also known as a secret key, is a cryptographic key that is used to decrypt or digitally sign data. It is a crucial component in asymmetric encryption algorithms like RSA and ECC ...

Hot on the heels of Diffie-Hellman upending the cryptography applecart in 1976 came three more crypto newcomers that further revolutionized the field: Ron Rivest, Adi Shamir, and Leonard Adleman. The ...

Israel-based researchers said they’ve developed a cheaper and faster method to pull the encryption keys stored on a computer using an unlikely accomplice: pita bread. The new study builds on research ...

The next time you stay in a hotel, you may want to use the door’s deadbolt. A group of security researchers this week revealed a technique that uses a series of security vulnerabilities that impact 3 ...

Every time you send a text, pay for groceries with your phone, or use your health site, you are relying on encryption. It’s an invisible shield that protects your data from prying eyes. Encryption is ...
