Abstract:
1. A mobile communication terminal device configured to perform encrypted communication with a communication system over a wireless connection, comprising: a detection unit configured to establish a communication activation procedure with the communication system, and configured to detect a security level that is used during the communication activation procedure with the communication system; an announcing unit configured to inform a user of the mobile communication terminal device about a strength of encryption of the detected security level from the communication activation procedure; a user interface operable by the user, configured to allow the user accept an incoming communication from the communication system, or is configured to allow the user to terminate the communication with the communication system, based on the detected security level; a data security setting unit allowing the user to set and store a reference security level for the mobile communication terminal device; and a comparison unit configured to compare the reference security level with the detected security level, and to either establish a communication with the communication system or accept an incoming communication from the communication system, if the reference security level is met, wherein the announcing unit is further configured to inform the user during the communication that has been established by said comparison unit that an actual security level of the communication has dropped below the reference security level.
