Abstract
Equipment (10, 20) for facilitating point-to-point cryptographic data communication systems is disclosed. The seamless rekey cryptosystem permits changing of the crypto key (70, 80) with no down time. The cryptosystem will facilitate seamless key installation to eliminate data loss or reduce storage required while updating the crypto key. The seamless key will allow changing the key more often, which will also provide a more robust, secure cryptosystem.
