Patent ID: 8553888

Claim:
A method for execution in a communication device, comprising: accessing an identifier stored in a memory; receiving a first data set and a second data set over a first communication path, wherein the first data set and the second data set are distributed by a control server, wherein upon receipt, the first data set is included within first encrypted data obtained by encrypting the first data set using a first key and the second data set is included within second encrypted data obtained by encrypting the second data set using the first key; decrypting the first data set from the first encrypted data using a second key that is complementary to the first key; decrypting the second data set from the second encrypted data using the second key; generating a first signature from the identifier and the decrypted first data set; generating a second signature from the identifier and the decrypted second data set; responding to a first request by releasing a first response including the first signature over a local communication path different from the first communication path; and responding to a subsequent request by releasing a second response including the second signature over the local communication path.
