In a method for real-time registration having high protection against tampering by means of a security module, an encrypted initial security value for translog file analyzers is made available an unencrypted real-time message is secured by appending an authentication code that the security module generates by inserting a current security value into an algorithm for authentication code for each real-time message that is likewise employed by each translog file analyzer. The first security value is formed according to a first mathematical function known to the translog file analyzer that allows a derivation of following security values. The authentication code is formed according to a second mathematical function known to the translog analyzer that is applied to the real-time message and to the current security value and that serves for the verification of the real-time message. A system for real-time registration has at least one client system and at least one translog analyzer for monitoring the authenticity of a translog file that had been generated by the security module.
