Abstract:
1. A method for facilitating secure data communications using a secret key for encrypting data flowing between first computing node comprising a processor and a memory and second computing node over a communications link, the method comprising: determining that the communications link has been idle for at least a predetermined period of time, the communications link intermittently fluctuating between idle and busy, the idle communication link having no secure data transmission within the at least a predetermined period of time; determining that there is secure data to flow over the idle communications link between the first computing node and the second computing node; and generating a new secret key on demand exclusively in response to determining that there is secure data to flow over the idle communications link and in response to determining that the communication link has been idle for at least the predetermined period of time, wherein the new secret key serves to encrypt the secure data sent between the first computing node and the second computing node over the communications link.
