pub struct CryptoIn {}Expand description
What the consensus controller asks of a signature scheme: the agreed
four streams, plus a one-time setup (seed and peers’ keys). A scheme is
any Synchronous component with I = CryptoIn, O = CryptoOut
(crypto::ed25519::Ed25519Crypto, DSig’s crypto::dsig), and the
replica is generic over it.
Streams (the layout both services share), sign layout v2 (ABI 2). The
signed context is 48 bytes, all LE: bytes 0..8 "RUB2" (low 4 bytes)
and the role (byte 4; 1 = certify share), 8..16 the session, 16..24
view | slot << 32, 24..32 k | m << 32, 32..48 reserved (zero today;
tail-CB instance context goes here, which DSig profile 2 also signs).
sign: one beat. Bytes 0..8 are the tag, bytes 8..56 the context. Ed25519 signs the context zero-extended to 64 bytes.sig: two beats. Beat 0 is the 64-byte share, beat 1 bytes 0..8 the tag;tlaston beat 1.verify: three beats. Beat 0 has byte 0 = the signer’s replica index (its key slot) and bytes 4..8 the tag; beat 1 is the context at bytes 0..48, zero-extended to 64 (the message as signed); beat 2 the share.tlaston beat 2.verdict: one word. Bits 0..8 are 0x80 if valid (else0x80 | code), 8..12 the slot, 32..64 the tag.
Fields§
§setup: boolSet up (one-cycle pulse).
n: b5Replicas.
id: b5This replica.
sk: [b64; 4]This replica’s private key (sk0..sk3).
keys_base: b64message_ptr: every replica’s public key, 8 words each.
msg: AxiReadRespmessage_ptr read answers.
sign: Axis512Sign requests.
sig_ready: boolsig tready.
verify: Axis512Verify requests.
verdict_ready: boolverdict tready.
announce_ready: boolannounce tready.
cfg: CfgWriteA host write into the scheme’s configuration window (s_axi_control 0x800..0xFFF, only while stopped). DSig takes its per-session namespace here; Ed25519 ignores it.
cert: Axis512A peer’s announce, fed back to the scheme: header beat (byte 0 =
the peer’s key slot), then its two announce beats; tlast on the
third. Schemes without announces keep cert_ready high.
