KaiABC
KaiABC is a cipher developed by Korean-American cryptographer, Daegyoon Baek, in 2007. The cipher is a block cipher, specifically a substitution-permutation network, that operates on fixed-length blocks of data. It is designed to be secure and efficient, with a focus on balancing key size and encryption speed.
The core components of KaiABC include a 512-bit block size and a 256-bit key size. The algorithm
Several studies and analyses have been conducted on the KaiABC cipher, including by the authors of the
KaiABC's use is not widespread, and it has not gained the same level of recognition as other
It's worth noting that while KaiABC has shown to be a secure cipher, its fixed block size
