One broadcast Data MAC Frame Stream for each of the connection based multicast/broadcast links with traffic terminating at the STA. For Associated but Unauthenticated STAs For each STA that is associated but not authenticated with its AVLN, a single Management MAC Frame Stream will be present (refer to Section 5.4.2). For Unassociated STAs Each Management Message that is received from any Unassociated STA and is currently being reassembled (i.e., the MME is being extracted from the Segment) will have its own MAC Frame Stream (refer to Section 5.4.3). Data Encryption As with HomePlug AV, encryption in HomePlug GREEN PHY STAs is performed independently on each PBB (padded segment). Once a segment has been formed for transmission, it will always occupy a single PBB by itself. It may require different padding and length fields on each retransmission, and it shall be re-encrypted on each retransmission. Section 13.4 describes the test vectors that are provided with this specification. It should eliminate any confusion about bit ordering, initialization vectors, etc. Encryption Method As with HomePlug AV, GREEN PHY STAs shall use 128-bit AES-based encryption in Cipher Block Chaining (CBC) Mode as the default encryption. The encryption algorithm shall be implemented in accordance with reference [2] Federal Information Processing Standards Publication 197 and reference [3] in Section 1.1. Also, refer to Section 7.10.6. PHY Block Body Encryption Bit Order The first in time bit of the PHY Block Body (LSB of octet 0) shall correspond to bit number 0 of the AES encoder defined in Section 3.1 of reference [2] Federal Information Processing Standards Publication 197. Initialization Vector Generation and Bit Order The Initialization Vector is generated from the Start of Frame Delimiter, the MPDU PB count, and from the PHY Block Header. Table 53 shows the format of the Initialization Vector. The LSB of octet number 0 of the IV shall correspond to bit number 0 of the AES encoder defined in Section 3.1 of reference [2] Federal Information Processing Standards Publication 197.
