1. Camellia: Japan’s representative cipher Recognizing that cryptographic technology has become an important foundation of the information society, a worldwide movement is taking place to select secure encryption algorithms as standard and recommended ciphers based on strict evaluations performed by cryptographic researchers. Camellia has been recognized as the only cipher in the world having security and processing performance levels equivalent to AES (Advanced Encryption Standard), the standard cipher of the United States government. Like AES, Camellia has been selected as a next-generation international standard cipher by various standardization organizations and projects. Camellia is expected to be used on the international level as Japan’s representative cipher. This article provides an overview of Camellia, discusses the significance of its selection by standardization organizations and projects, and describes how NTT is working to promote the use of Camellia now and in the future. 2.
