A system and method for the cryptographic exchange of information is provided which affords maximum security, process simplicity and participant convenience to any software application, business process or device used to communicate messages. The system provides the ability to openly exchange encryption keys for each communication between participants in a totally secure fashion. Along with the key exchange, the system and method can be used to secure all accompanying message content with a derived message key. The system and method derives the message key in such a manner that the original encryption key cannot positively be determined from a discovered message key. The system and method additionally provide a technique for authenticated exchange of new encryption keys such that the new key is completely dissimilar from any previous key, effectively eliminating any chained key knowledge.
