  • Methods, encoder and decoder using encryption and authentication functions for encrypting and decrypting a message
    Patent number: 11546146
    Abstract: An encoder encrypts a message by generating a nonce, using a first encryption key to encode the nonce, splitting the message into a first part and a second part, using the first encryption key and the encoded nonce to encrypt the first part of the message into a first ciphered part, using a second encryption key, the encoded nonce and the first ciphered part to generate an initialization vector, using the first encryption key and the initialization vector to encrypt the second part of the message into a second ciphered part, and generating a ciphertext comprising the first ciphered part, the second ciphered part, the initialization vector and the nonce. A decoder uses a reverse process to decrypt the message. The decryption comprises generating a copy of the initialization vector, which is compared to the initialization vector in order to verify that the message is properly decrypted.
