Abstract: An initialization vector (IV) is employed to decrypt a block of a stream that has been encrypted with Cypher Block Chaining (CBC) encryption, without requiring decryption of previous blocks within the stream. For example, a listener who accesses a distribution point to retrieve encrypted content authenticates himself to an application server that regulates access to encrypted content on the distribution point, and responsively receives a key. The listener then requests access to a reference point within the encrypted content stream somewhere after its beginning (e.g., using preview clips). The distribution point relates the reference point to a corresponding block of the encrypted stream, and identifies an IV previously used for encryption of that block. The distribution point provides the associated encrypted block of content and the IV to the listener to enable mid-stream rendering of the encrypted content, without requiring the listener to decrypt previous blocks within the encrypted stream.

Abstract: It is useful to provide a mechanism to allow, at least temporarily, communications to occur without blocking between a first entity and a second entity with whom communications with the first entity are likely/anticipated and desirable, generally through use of a white-list having transactional entries. For example, to allow communications between a communications user and an intended recipient, the user may be added to global and/or personal white-lists for or until a specified transaction or duration. Thereafter, the user may be removed from the white-lists upon occurrence of an end trigger, which may include an event or expiration of a specified time. The disclosed systems and methods thus permit the transactional white-listing of users for a limited time necessary to ensure the intended recipient receives the anticipated communications. Thereby, the systems and methods guard against the anticipated communications being accidentally blocked as spam by other communications filters.
