Since ancient times, people have relied on cryptography, the art of writing and solving coded messages, to keep their secrets secure. In the fifth century, enciphered messages were inscribed on ...

When I began programming microcontrollers in 2003, I had picked up the Atmel STK-500 and learned assembler for their ATtiny and ATmega lines. At the time I thought it was great – the emulator and ...

Reports began surfacing in October that Chinese researchers used a quantum computer to crack military-grade AES 256-bit encryption. Those reports turned out to be wrong, but that did little to dampen ...

Once quantum computers become a commercial reality, they will change the ground rules for cryptography. Here's how quantum cryptography would work, and an explanation of the benefits and pitfalls of ...

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 ...
