1. A transmission system for transmitting information from an originator to a mobile device, the transmission system comprising:
- an originator component configured to receive the information to be transmitted and form a transmission message; and
wherein the originator includes;
a first encryption key component configured to derive a first encryption key based on a base key known by the receiver component, a first data string and a data portion including transmission message specific data derived from the information to be transmitted;
a second encryption key component configured to derive a second encryption key based on the base key, a second data string and the data portion;
an encryptor configured to hash the information to be transmitted with the first encryption key to obtain a signature and to encrypt the information and the signature with the second encryption key to obtain an encrypted message; and
a joiner configured to join the encrypted message with the transmission message specific data, in unencrypted form.
