Minalpher

Minalpher is an authenticated encryption algorithm submitted to CAESAR (Competition for Authenticated Encryption: Security, Applicability, and Robustness) as a candidate of a new standard algorithm. Performance evaluation of Minalpher in various software and hardware have been made. Especially, the algorithm is suitable for high-speed hardware implementation by utilizing its parallel operating capability. Therefore, we implemented the high-speed Minalpher software on GPGPU (General Purpose Graphic Processing Unit) that provides massive parallel computing. Its performance is compared with Minalpher on CPU and a de-facto standard AES-GCM on GPGPU.
