Abstract:
1. A method of loading data into a mobile terminal data comprising payload data and header data, the method comprising the steps of: receiving a header message from a loading station by a mobile terminal wherein the header message includes the header data having a cryptographic data item including a cryptographic checksum based on a message digest of the message calculated by a hash function; verifying the received header data by the mobile terminal; receiving the payload data, if the header data is verified successfully; accepting the payload data by the mobile terminal conditioned on a verification process based on the header data, wherein the payload data is divided into a number of blocks of payload data and the blocks of payload data do not carry authentication information; wherein receiving the payload data further comprises receiving a number of payload messages each including one of the number of blocks of payload data; and wherein accepting the payload data further comprises accepting each of the blocks of payload data by the mobile terminal conditioned on a cryptographic verification process based on a corresponding one of a number of received message digests and accepting the payload data conditioned on a verification of a received message digest calculated from a combination of all blocks of payload data.
