The National Security Agency (NSA) has certified the secure phone’s ability to protect classified voice and data communications up to the Top Secret level using the Type 1 encryption algorithm available to authorized U.S. Government personnel. The phone also implements the Advanced Encryption Standard (AES), approved as a replacement for the 1977 Data Encryption Standard (DES) by the National Institute of Standards and Technology (NIST) in 2002, to protect sensitive and private communications for government, business and international users. The phone is available with multiple key-sets to support U.S. Government sponsored interoperability (e.g., NATO and coalition). It complies with SCIP (Secure Communications Interoperability Protocol) standards and will securely interoperate with other SCIP-compatible devices. The Military Committee for the NATO Communications and Information Systems Security and Evaluation Agency (SECAN) has approved the Sectéra Secure Wireless Phone for GSM and Sectéra Wireline Terminal for the encryption of all levels of NATO classified information.
