A long-sought “holy grail” in cryptography is poised to change the way we protect sensitive information. Today’s standard encryption schemes take an all-or-nothing approach. Once scrambled, your data ...

Cryptographers want encryption schemes that are impossible for tomorrow’s quantum computers to crack. There’s only one catch: they might not exist. When we check email, log in to our bank accounts, or ...

The original version of this story appeared in Quanta Magazine. In our increasingly digital lives, security depends on cryptography. Send a private message or pay a bill online, and you’re relying on ...

To understand the difference between quantum cryptography and post-quantum cryptography, it’s helpful to go back in time: In the early 1990s, Peter Shor of AT&T Bell Laboratories discovered an ...

Understand the crypto concepts behind the modern internet security infrastructure, from digital signatures and transport layer security to blockchains and Bitcoin. Cryptography grows ever more ...

In 2018, Aayush Jain, a graduate student at the University of California, Los Angeles, traveled to Japan to give a talk about a powerful cryptographic tool he and his colleagues were developing. As he ...

For the first time, researchers have demonstrated that a large portion of cryptographic keys used to protect data in computer-to-server SSH traffic are vulnerable to complete compromise when naturally ...

Author Nick Sullivan worked for six years at Apple on many of its most important cryptography efforts before recently joining CloudFlare, where he is a systems engineer. He has a degree in mathematics ...
