SNOW-V Stream Cipher Engine is a high-performance cryptographic IP designed by CAST to offer swift and reliable encryption for modern communication systems. Built upon the specifications set forth by IACR in 2009, it utilizes a 256-bit key and a 128-bit initialization vector (IV) to generate 128-bit keystreams per cycle. This implementation is tailored for applications that demand high speed and security, making it suitable for wireless communications and scenarios where data protection and efficiency are critical.
