![]() It can serve as an encryption/decryption point. It has a dedicated 3-wire KFD interface, and includes a complete key storage and critical security material management function for TEK, KEK, UKEK, CKEK and KSK keys, with protection from unauthorized disclosure or modification. The P25 Console Gateway has one capability that the TB9100 base station does not have. APCO Project 25 is the digital communications standard used by many police and emergency services throughout the. The Etherstack Cryptographic module meets the Security Requirements for Cryptographic Modules standard from the National Institute of Standards and Technology (NIST). APCO Project 25 Common Air Interface (P25). The module supports AES / DES P25 Encryption Engine plus P25 Key Fill Device (KFD) protocol support, P25 Over-The-Air-Rekeying (OTAR), New Link Layer Authentication (LLA) and P25 Key Management Facility (KMF). It can be used to provide FIPS 140-2 compliant encryption services to APCO P25 mobile, portable and base stations – or any other end point for voice or user data in a P25 network. Using cheap RTL-SDR dongles with software like DSD+ can also be used, but OP25 can decode more systems and show you low level information, even decrypt. The Etherstack FIPS 140-2 Cryptographic Module is a single-board security device that implements APCO P25 encryption, decryption, key management and key storage services in conformance with FIPS140-2 standards. Encryption is the conversion of data into a form called a cipher text that cannot easily be understood by unauthorized personnel.
