In theory and practice, Navajo is not much different from most existing public key cryptosystems. It encodes the encryption keys, performs the key exchange, encrypts the message and then sends it to the recipient. The difference is in the manner in which the key is encoded and distributed to the recipient.
One other key difference in Navajo is its key regeneration rate. In practice, many commercial cryptosystems are set to generate new keys infrequently, if ever. This can lead to a situation where an attacker can read supposedly secure communications ad infinitum if he or she is able to compromise the encryption key. Instead, MagiQ's system refreshes its keys continuously.
Pricing for Navajo starts at $50,000 per endpoint.
