What do the Gallic Wars and online shopping have in common? The answer, believe it or not, is cryptography. Cryptography is the cement of the digital world, but it also has a long history that ...

A basic feature of number theory, prime numbers are also a fundamental building block of computer science, from hashtables to cryptography. Everyone knows that a prime number is one that cannot be ...

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 ...

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 ...

Given the recent ubiquity of cyber-scandals—Colin Powell’s stolen e-mails, Simone Biles’s leaked medical records, half a billion plundered Yahoo accounts—you might get the impression that hackers can ...

Kimmo Järvinen is a hardware cryptography engineer and researcher with nearly 20 years of experience in the field. He has authored more than 60 scientific publications on cryptography, cryptographic ...

A new and much faster quantum cryptography protocol has been developed: Usually, quantum cryptography is done with photons that can be in two different states. Using eight different states, ...
