Abstract:
1. A computer-implemented method of secure communication of digital data between a first device and a second device, said method comprising: receiving a first device identifier and a first random number from the first device and a second device identifier and a second random number from the second device by a security module comprising a processor; making a first determination, by the processor, that the first device identifier matches at least a first stored identifier in the security module; making a second determination, by the processor, that the second device identifier matches at least a second stored identifier in the security module; in response to the first determination and the second determination, validating, by the processor in the security module, the first and second device; generating, by the processor, a random key in the security module in response to successful validation of the first and second device; transmitting the random key encrypted by the first random number to the first device; and transmitting the random key encrypted by the second random number to the second device, wherein after the random key encrypted by the first random number is decrypted by the first device and after the random key encrypted by the second random number is decrypted by the second device, the random key enables the secure communication of the digital data between the first and second device.
