Federated Authorization
Infrastructure for Regulated
Digital Ecosystems
Protocol-level identity and authorization trust layer enabling retail, financial, healthcare, and sovereign deployments.
Architecture Overview
The KeyIdentity Federation Protocol defines a layered architecture for identity issuance, authorization binding, and cross-domain trust propagation.
Edge-First Identity Verification
Biometric enrollment and verification execute at the edge appliance. Identity artifacts never leave the local trust boundary unless explicitly exported under governance policy.
Cloud-Issued Federated Identity Keys
The federation authority issues short-lived, cryptographically bound identity keys scoped to a specific trust domain and authorization context.
Retailer-Scoped Authorization Tokens
Authorization tokens are scoped to the requesting merchant, encoding transaction limits, risk thresholds, and policy constraints enforced at verification time.
Governed Identity Export
Identity portability between trust domains is mediated by governance policy. Export requires explicit consent, audit logging, and root authority attestation.
Multi-Root Federation
The protocol supports multiple federation roots operating under distinct governance charters, enabling consortium, sovereign, and enterprise trust topologies.
Retail Infrastructure at Scale
Purpose-built for multi-location retail environments where identity verification must operate reliably at the physical edge, under real-world network conditions.
Multi-Location Deployment
Centrally managed, locally executed. Each location operates its own edge trust boundary with fleet-level policy synchronization.
Certified Edge Appliances
Hardware-attested compute nodes with tamper detection, secure boot chain, and local biometric processing. No cloud dependency for verification.
Fleet Management
Centralized device provisioning, firmware updates, health monitoring, and certificate rotation across the entire appliance fleet.
Cryptographic Fraud Reduction
Identity-bound authorization eliminates credential sharing, replay attacks, and synthetic identity fraud through per-transaction cryptographic proof.
Network Overlay Compatibility
Operates over existing retail network infrastructure. Compatible with SD-WAN, MPLS, and standard internet connectivity with end-to-end encryption.

KeyIdentity Federation Protocol
KIFP is a versioned, formally specified protocol governing identity issuance, federation trust establishment, and cross-domain authorization across independent trust roots.
Multi-Root Capable
Independent federation roots operate under distinct governance charters with formally defined trust boundaries.
Root Registry
A verifiable registry of federation roots with published trust parameters, governance charters, and revocation endpoints.
Federation Tiers
Tiered participation model from observer to full federation member, with graduated trust and capability levels.
Versioned Protocol
Semantic versioning with backward compatibility guarantees. Protocol upgrades require formal governance approval.
PQ-Ready Cryptographic Path
Algorithm agility layer supports migration to post-quantum cryptographic primitives without protocol revision.
Governance & Trust
Federation trust is not self-asserted. It is established through formal governance processes, maintained through continuous attestation, and revocable at every level.
Root Admission Model
New federation roots undergo a structured admission process including technical audit, governance charter review, and existing-member ratification before trust is established.
Revocation Framework
Multi-layer revocation at the root, domain, identity, and token level. Revocation events propagate across the federation within defined latency bounds.
Trust Council Evolution
Governance decisions are made by a Trust Council with defined quorum rules, term limits, and conflict-of-interest policies. Charter amendments require supermajority.
Compliance Readiness
Architecture and operational controls aligned with SOC 2 Type II, ISO 27001, and PCI DSS. Audit artifacts are generated continuously, not retroactively.
Deployment Models
KeyIdentity operates across deployment topologies ranging from fully managed cloud to air-gapped sovereign installations.
Public Cloud
Fully managed federation infrastructure on KeyIdentity-operated cloud. Multi-region availability, automated scaling, and continuous compliance monitoring.
Managed SaaS
Sovereign Regional
Dedicated infrastructure deployed within national or regulatory boundaries. Data residency guarantees enforced at the protocol level. Supports air-gapped operation.
Data sovereignty
Consortium Federation
Multi-party federation where participating organizations operate independent trust roots under a shared governance charter. No single point of control.
Multi-root governance
Retail Enterprise (HaaS)
Hardware-as-a-Service delivery of certified edge appliances with centralized fleet management, firmware lifecycle, and integrated identity verification.
