Nippon Telegraph and Telephone Corporation (NTT) and Mitsubishi Electric Corporation (Mitsubishi) announced their joint development of "Camellia," a next-generation symmetric-key encryption algorithm". Next-generation symmetric-key encryption algorithms with high security and efficiency on various platforms are indispensable for ensuring the secrecy of corporate and individual private information in the advanced information society. The new next-generation encryption algorithm Camellia is a symmetric-key encryption algorithm with a block size of 128 bits. It was developed by NTT and Mitsubishi using NTT's cipher design technologies geared to high speed software implementation, Mitsubishi's cipher design technologies for compact and highspeed hardware implementation, and state-of-the-art security evaluation technologies of both companies.
