GHL Systems’ NetMATRIX TLE uses symmetric key encryption and decryption which is more suitable in an environment where processing power; memory and bandwidth are limited – where up to 4 Billion unique keys per terminal application and also supports Unique Key Per Transaction. Additionally, the NetMATRIX TLE uses Dynamic Key Derivation instead of Static Keys for each transaction effectively preventing Terminal Cloning and reducing Key Management issues. It further provides a Remote Key Injection (RKI) utility to ease the deployment of Keys into terminals, remotely.
