Abstract:
1. A method of generating, by a mobile communication network device, a shared secret data having a length of M units, the method comprising the steps of: performing, by the mobile communication network device, a first operation on groupings of one of N units of a randomly generated base shared secret data and one of a plurality of secret values thereby generating a plurality of first operation results, the randomly generated base shared secret data having a length of N units, where N is less than M; mapping each of the N units of the base shared secret data and the plurality of secret values to corresponding secret integer values prior to performing the first operation; performing, by the mobile communication network device, a second operation on a select plurality of the first operation results thereby generating a plurality of second operation results; and constructing, by the mobile communication network device, the shared secret data by combining in a specific order at least one of the first operation results and at least one of the plurality of second operation results.
