Harris customizable cryptographic architecture

The need for protection of information has dramatically increased as equipment that can be used for interception of sensitive data has become more readily available. The need to secure non-DOD sensitive data in both the government and private sectors has required the development of very robust, high grade information security solutions that can be tailored to meet specific security needs. Harris has made a long term R&D investment into developing a robust information security architecture, that can be used in applications where Type I security is not required. The architecture is based on Harris´s proprietary cryptographic algorithm technology. It supports sensitive but unclassified (SBU) requirements and international markets requiring customer unique encryption. It is an ideal solution for the protection of defense and other national level interests, and provides state-of-the-art protection for both domestic and international users over any of the media used in modern communications. The first embedment of this architecture is the CITADEL^TM integrated circuit. CITADEL^TM is Harris´ prime export encryption solution for all of its new products requiring security, such as the FALCON II HF, VHF, and multi-band radio platforms. This paper presents an overview of the Harris customizable cryptographic architecture and discusses various applications in which the CITADEL^TM can be used
