DEVELOPMENT APPROACHES FOR AN INTERNATIONAL TACTICAL

Currently, there are no internationally available application programming interfaces (APIs) for the embedded cryptographic module of modern tactical radios which comply with the Joint Tactical Radio System (JTRS) Software Communications Architecture (SCA). We survey relevant, internationally released documents including recommendations from the SDR Forum Security Working Group, publicly released information on the Common Interfaces to Cryptographic Modules (CICM) project and SCA specifications including the SCA 3.0 Security Supplement. These and other documents are examined as the possible basis for a draft Cryptographic API employing common interfaces for an embedded cryptographic module usable by an International Tactical Radio (ITR) and Waveform Development Environment (WDE). The draft Cryptographic API can be used as the basis for a future recommendation by the SDR Forum Security Working Group.
