Project

Implementing and optimizing encryption algorithms for the ARMv8-A architecture

Project (M.S., Computer Science)--California State University, Sacramento, 2014.

This project exploits the cryptographic and data processing capabilities of the ARMv8-A
 chip to produce fast and efficient encryption algorithms. Basic AES encryption and
 decryption algorithms are produced, and these algorithms are then utilized in more
 sophisticated encryption schemes.
 
 The ARM architecture is a family of instruction set architectures, all of which are RISC based. Currently, ARM is the most widely used instruction set, and can be found in
 devices such as televisions, computers, and mobile phones.
 
 The newest version of ARM, ARMv8-A, released in 2011, is a 64-bit architecture.
 Included in the ARMv8-A is a NEON SIMD engine that allows for accelerated data
 processing of all kinds, including AES encryption and decryption, as well as SHA-
 1/SHA-2 hashing. This project uses ARM NEON intrinsics to access these data
 processing capabilities.
 
 The Apple A7 chip (known as Cyclone) was first released in products in 2013 and was
 the first ARMv8-A CPU available to consumers. The A7 chip can be found in the iPhone
 5S, the iPad Air, and the iPad Mini (second generation). The iPad Air was the target for
 the software produced for this project, allowing the cryptographic capabilities of the
 ARMv8-A to be explored and exploited.
