Abstract
In a general aspect, a key encapsulation mechanism is used in a communication network. In some aspects, an error vector derivation function is applied to a random value to produce an error vector, and a plaintext value is obtained based on the random value. The error vector and the plaintext value are used in an encryption function to produce a ciphertext, and a key derivation function (KDF) is applied to the random value to produce a key derivation function output that includes a symmetric key and a confirmation value. The symmetric key is used to generate an encrypted message based on an unencrypted message. The ciphertext, the confirmation value, and the encrypted message are provided for transmission in a communication network.
