Can we validate in middleware, not only player clients?

Cryptographic and transport foundations behind Attestik

Attestik pairs deterministic encoding, signature verification, and transport-aware embedding to keep claims intact from origin to playback.

Security models are often under-specified between encoding, transport, and player verification.

Verification logic diverges across teams, creating inconsistent enforcement behavior.

Protocol upgrades can break compatibility without strong versioning discipline.

Silent signature or chain validation failures in distributed systems.

Parsing inconsistency across codecs and container pathways.

Operational drift between spec and production implementations.

Deterministic byte-level verification behavior.

Consistent transport bindings across major delivery protocols.

Versioned interoperability with clear conformance levels.

Use strict frame headers, canonical payload encoding, and explicit signature inputs.

Map SIP payload carriage for SEI, OBU, and manifest/metadata pathways.

Define validation procedures and profile levels for reliable cross-vendor behavior.

Compact signatures with fast verification for stream-scale workloads.

Canonical serialization eliminates signer/verifier byte mismatch classes.

Full, delta, and heartbeat frames balance verification depth and runtime overhead.

SIP v1.0.1 defines normative transport and verification procedures with explicit invariants.

Frame cadence is tunable with compact delta/heartbeat modes for practical production budgets.

Yes. SIP verification can run in middleware, gateways, and player applications.
