STREAM is a a construction which, when combined with AES-SIV or AES-PMAC-SIV, provides online/streaming authenticated encryption and defends against reordering and truncation attacks.

The algorithm is described in the paper Online Authenticated-Encryption and its Nonce-Reuse Misuse-Resistance in which it is formally proven to have the properties of a nonce-based online authenticated encryption (nOAE) construction (see Section 7, p. 18).
