GENERATION OF COMMUNICATION DEVICE SIGNATURES FOR USE IN SECURING NOMADIC ELECTRONIC TRANSACTIONS
First Claim
1. 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;
generating a first signature from the identifier and the first data set;
generating a second signature from the identifier and the 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.

Abstract
A method for execution in a communication device, which comprises accessing an identifier stored in a memory; receiving a first data set and a second data set over a first communication path; generating a first signature from the identifier and the first data set; generating a second signature from the identifier and the 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.

33. A computer-readable storage medium comprising a set of instructions for execution by a processing entity of a communication device, wherein execution of the set of instructions by the processing entity causes the processing entity to execute a method that includes:
-
accessing an identifier stored in a memory; receiving a first data set and a second data set over a first communication path; generating a first signature from the identifier and the first data set; generating a second signature from the identifier and the 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.

34. A communication device, comprising:
-
a memory storing an identifier; an interface configured to communicate over a first communication path and over a local communication path different from the first communication path; and a processing entity configured to; receive from the interface a first data set and a second data set received over the first communication path; receive from the interface a first request and a subsequent request received over the local communication path; generate a first signature from the identifier and the first data set; generate a second signature from the identifier and the second data set; respond to the first request by releasing a first response including the first signature via the interface over the local communication path; and respond to the second request by releasing a second response including the second signature via the interface over the local communication path.
