Abstract
In a general aspect, a conversion scheme is used in a public key cryptosystem. In some aspects, an error vector derivation function is applied to a random value and a message value to produce an error vector. A plaintext value is generated based on the random value, the message value, and the error vector. The error vector and the plaintext value are used in an encryption function to produce a ciphertext component, and the ciphertext component is provided for transmission in a communication system.
