In various aspects, the present disclosure is directed to a device and method enabling communication only in case of a personal identification. In some aspects, a communication device is provided, the communication device comprising a transponder unit configured for at least one of sending data to and receiving data from another communication device, a biometric sensor unit configured to sense biometric data of a user of the communication device, and a security interface unit arranged between the transponder unit and the biometric sensor. Herein, the security interface unit is configured to enable the transponder unit for at least one of sending and receiving data upon biometric data sensed by the biometric sensor being verified as representing verified biometric data, and the transponder unit comprises a communication interface having a state machine. The state machine being enabled independently from the biometric data sensed by the biometric sensor unit being verified by the security interface as representing verified biometric data.

Communication device and method of using such a communication device

The present disclosure provides in various aspects an encryption device (), a communication system and a method of exchanging encrypted data in such a network. In accordance with some illustrative embodiments of an aspect, the encryption device () comprises a communication interface (), a variable key generator () configured to generate at least two keys, a memory () configured to store keys that are either generated by the variable key generator () and/or received at the communication interface (), and an encryption/decryption component () configured to successively use keys stored in the memory () for encrypting a plaintext received at the communication interface () and for decrypting a ciphertext received at the communication interface (), wherein the communication interface () is configured to communicate with an associated separate communication device which is used by a user of the encryption device () for communicating in a communication network.
