Abstract:
1. A machine-implemented method implemented on a sender machine having a processor and a memory, the method comprising: the processor encrypting a first segment of a message, therein forming an encrypted first message segment, wherein the processor encrypting the second set of keys with the first group of keys, therein forming an encrypted second set of keys, each key of the first group of keys being used in the encrypting of the first message segment or the encrypting of the second set of keys; the processor encrypting a second message segment with at least one key from a second group of keys, therein forming a second encrypted message segment, wherein the second group of keys includes the second set of keys and at least one other key; and the processor encrypting a third set of keys with the second set of keys, therein forming an encrypted third set of keys.
