What is the primary purpose of the KYV-5 (AN/USC-43)?

Explanation:
It provides secure two-way communications by handling both encryption of outgoing messages and decryption of incoming ones. The KYV-5 is a two-way crypto device used with the AN/USC-43 system, designed so that at the transmitting end plaintext is encrypted before transmission and at the receiving end ciphertext is decrypted back to plaintext, using a shared cryptographic key. This dual capability ensures confidentiality in both directions of the link. It isn’t about increasing data rate, and it isn’t limited to just encryption or just decryption—the core purpose is to enable both processes to secure communications.
