Abstract
One embodiment is directed to a method performed by a computing device. The method includes (a) engaging in a handshake procedure with a remote second computing device to establish a secure channel, (b) generating a first encryption key using a first token having a secret seed, the first encryption key being the same as a second encryption key generated by the second computing device using a second token having the same secret seed, and (c) using the first encryption key to engage in encrypted communications with the second computing device. Other embodiments are directed to a computerized apparatus and a computer program product for performing a method similar to that described above.
