To send a message, N secret keys are negotiated using a noisy cryptographic system, where K secret keys are expected to be noiseless. A secret polynomial that includes the N secret keys is generated, and K points on the secret polynomial are derived. For each of the N secret keys, a secret key MAC key is derived and a secret key MAC is calculated using the derived secret key MAC key. A secret key MAC header is generated that includes an array of each of the secret key MACs and possibly a corresponding public key. Message integrity plaintext is generated that includes an encrypted message, the secret key MAC header, and an array of the K points on the secret polynomial. A final message that includes the message integrity plaintext is generated for being sent."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Error-correcting key agreement for noisy cryptographic systems","description":"A system, method, and computer program product are provided for sending and receiving messages using a noisy cryptographic system.
