Since communications may be garbled, intentionally altered, or destroyed, the availability of cryptographic information after transit cannot be assured using cryptographic methods. However, availability can be supported by redundant or multiple channels, store and forward systems (deleting by the sender only after confirmation of receipt), error correction codes, and other non-cryptographic mechanisms. Communication systems should incorporate non-cryptographic mechanisms to ensure the availability of transmitted cryptographic information after it has been successfully received, rather than relying on retransmission by the original sender for future availability
