This application note presents the implementation of AES-128 encryption with Zilog’s Z8 Encore! series of 8-bit microcontrollers. It briefly describes the Advanced Encryption Standard (AES), and the ...

“xor” denotes bit-by-bit modulo-two addition of bytes “add” denotes modulo-256 addition of bytes “exp” denotes 45x modulo 257, with the convention that the result 45128=256 is represented by 0 “log” ...

Researchers from Microsoft and the Dutch Katholieke Universiteit Leuven have discovered a way to break the widely used Advanced Encryption Standard (AES), the encryption algorithm used to secure most ...

A group of researchers have developed a new attack that enables them to find AES keys several times faster than was previously thought possible, reducing the complexity of finding the keys on AES-128, ...

Threats to computer and network security increase with each passing day and come from a growing number of sources. No computer or network is immune from attack. A recent concern is the susceptibility ...
