1. A method involving a communication device, comprising:
- sending a request to a communication device;
receiving a response from the communication device over a local communication path;
deriving a received data set from said response;
determining at least one data set that had been previously transmitted to the communication device over a second communication path different from the local communication path; and
validating the response based on the received data set and the at least one previously transmitted data set.

43. A computer-readable storage medium comprising a set of instructions for execution by a processing entity, wherein execution of the set of instructions by the processing entity causes the processing entity to execute a method of validating a response received from a communication device over a local communication path, the response having been sent by the communication device in response to a request sent thereto, the method comprising:
-
deriving a received data set from the response; determining at least one data set that had been previously transmitted to the communication device over a second communication path different from the local communication path; and validating the response based on the received data set and the at least one previously transmitted data set.

44. A system, comprising:
-
a control server configured to generate at least one particular data set for transmission to a particular communication device over a first communication path; transmit/receive equipment configured to send a request to a detected communication device over a local communication path different from the first communication path and to obtain a response from the detected communication device over the local communication path; and a processing entity communicatively coupled to the transmit/receive equipment and to the control server, the processing entity configured to derive a received data set from the response; wherein upon identifying the detected communication device as the particular communication device, the processing entity is configured to validate the response based on the received data set and the at least one particular data set. - View Dependent Claims (45, 46, 47, 48, 49, 50, 51, 55, 56, 57, 58, 59)
