server uses an authenticated encryption scheme ([AEAD](#aead)) to en/decrypt and authenticate the object content. The AEAD is combined with some state to build a *Secure Channel*. A *Secure Channel* is a cryptographic construction that ensures confidentiality and integrity of the processed data. In particular the *Secure Channel* splits the plaintext content into fixed size chunks and en/decrypts each chunk separately using a unique key-nonce combination.
