Bit Allocation Proposed for MT51 at 250 bits per Message
| MT51 Bit Allocation | |||||
|---|---|---|---|---|---|
| Preamble | MT | Reserved | Payload Metadata | OTAR Payload Segment | CRC |
| 4 | 6 | 4 | 84 | 128 | 24 |
Note: Table 3 describes the metadata which specifies how a receiver should interpret the payload. The Authentication Stack, defined in Section 2.5, is composed of a total 2048 bits and required the receipt of the 16 unique messages to OTAR.
