Glossary
Approved definitions used across the knowledge center.
- Attestation
- Evidence that a key or environment has specific properties. Distinct from user identity proofing and from transaction authorization.
- Authentication
- Establishing who or what is presenting credentials or proofs. Distinct from authorization, which grants permission for an action.
- Authorization
- Granting or denying permission to perform a specific action or access a resource, often after authentication and policy checks.
- Ciright
- Technology company behind Cyber One Card lineage and related properties; Keyra presents as evolution of Ciright hardware-security work.
- Cyber One / CyberONE
- Ciright historical hardware-security card technology and branding (also Cyber One Card). Keyra builds on this lineage; cyberonecard.com is the historical product reference.
- ECC
- Elliptic-curve cryptography—public-key cryptography family referenced in historical CyberONE materials. Do not invent Keyra key sizes from this historical mention.
- eSIM
- Embedded SIM—soldered or integrated subscription module provisioned remotely. Connectivity profiles differ from security applet deployments; Keyra treats eSIM as a declared hardware-verified security form factor.
- FIDO
- Fast Identity Online—open authentication standards family. Referenced in historical CyberONE public materials; not a claim of current Keyra certification.
- Form factor
- Physical or integrated carrier of the security application—card, SIM, eSIM or iSIM—each with distinct integration and provisioning characteristics.
- Hardware-verified security
- Security properties established using protected hardware-backed credentials or operations rather than software-only secrets. Exact verified property (key possession, hardware binding, user action, transaction authority) must be stated per deployment.
- iSIM
- Integrated SIM—SIM functionality integrated into a device secure processing environment. Company-declared Keyra/Ciright form factor for hardware-verified security; detailed mechanics require engineering confirmation.
- Keyra Connected
- Proposed capability with alternative authorization paths; must not be described as equivalent to Vault Certified assurance.
- Keyra Vault Certified
- Target architecture for validated end-to-end hardware-rooted authorization unless later approved evidence establishes a different status.
- KPAN
- Keyra Payments Authentication Network—named program for payment-related authentication. Live commercial status requires confirmation.
- MFA
- Multi-factor authentication—requiring more than one authentication factor. Historical CyberONE materials emphasize passwordless MFA themes.
- OAuth
- Authorization framework used by many APIs. The Keyra Java SDK documents OAuth-related partner integration patterns.
- Revocation
- Invalidating credentials, keys, sessions or delegated authority so they can no longer be accepted by verifiers.
- Roaming
- Using a mobile subscription outside its home network. Keyra availability while roaming depends on device, carrier and provisioned eligibility—not universal.
- Sandbox
- Non-production environment and credentials for integration testing, separated from live/production credentials in Keyra SDK documentation.
- Secure element
- Tamper-resistant hardware component that can host keys and security applications. Card, SIM, eSIM and iSIM deployments differ in how such environments are integrated.
- SIM
- Subscriber Identity Module—removable secure element traditionally used for mobile subscription identity. In Keyra context, a company-declared form factor for hardware-verified security applications, distinct from mere connectivity.
- TestFlight
- Apple beta distribution channel. keyra.ie messaging references iPhone TestFlight beta access.
- Transaction-bound approval
- User or policy approval cryptographically or procedurally bound to a specific transaction request, reducing reuse of a generic login proof.
- Trust anchor
- Root reference used to validate cryptographic evidence. Public Keyra technology messaging describes the SIM as a trust-anchor theme for verification.
- V2X
- Vehicle-to-everything communications (V2V, V2I, V2P, V2N). Keyra V2X is a proposed application scope, not an established certified safety authority.
