- New TLS Message Processing Stack (MPS)
The TLS 1.3 prototype is developed alongside a rewrite of the TLS messaging layer,
encompassing low-level details such as record parsing, handshake reassembly, and
DTLS retransmission state machine.
MPS has the following components:
- Layer 1 (Datagram handling)
- Layer 2 (Record handling)
- Layer 3 (Message handling)
- Layer 4 (Retransmission State Machine)
- Reader (Abstracted pointer arithmetic and reassembly logic for incoming data)
- Writer (Abstracted pointer arithmetic and fragmentation logic for outgoing data)
Of those components, the following have been upstreamed
as part of `MBEDTLS_SSL_PROTO_TLS1_3_EXPERIMENTAL`:
- Reader ([`library/mps_reader.h`](../../library/mps_reader.h))
