摘要： A portable electronic data module for secure transactions, the electronic data module having a random number generator and an optimized co-processor for producing unbreakable key sets for a two-key cryptosystem. A real-time clock is sampled depending upon an external random event series such as power-ups of the data module by a host apparatus, and based upon the contents of the sample thus obtained, the entropy of a previously-loaded accumulator is further enhanced to achieve a pool of true random numbers. By repeatedly requesting random bytes of information from said pool of random numbers, large random numbers are created which are then rendered prime and used for key set creation.
