Method and system for real time recording with security module

摘要

A security module (11) generates an authorization code by inserting an up-to-date security value in an algorithm used by every translog file analyzer (20,30) for an authorization code for every real-time message. A first security value copies a first mathematical function recognized by the translog file analyzer to permit a deviation from subsequent security values. The authorization code copies a second mathematical function also recognized by the translog file analyzer and applied to the real-time message and the up-to-date security value. The second mathematical function serves to verify the real-time message. An Independent claim is also included for a system for real-time recording that has a client system (10).
