Abstract
The present invention is directed to a method for efficiently and individually encrypting control commands, which makes it possible to encrypt supplied applications and to transmit them to an end device not only in an efficient but also in a particularly secure way.
Claims16
-15. (canceled)
A method for efficiently and individually encrypting control commands for single end devices, comprising the steps of:
- supplying a set of control commands by means of a telecommunication network;
- identifying a subset of the control commands which supply a security-critical functionality;
- and
- encrypting merely the subset of control commands, wherein the encrypting is effected in dependence on an end device identifier.

An encryption apparatus for efficiently and individually encrypting control commands for single end devices, comprising:
- an interface unit arranged to supply a set of control commands by means of a telecommunication network;
- an analyzing unit arranged to identify a subset of the control commands supplying a security-critical functionality;
- and
- an encryption unit arranged to encrypt merely the subset of control commands, wherein encrypting is effected in dependence on an end device identifier.
