Term Definition
Device key A cryptographic key associated with the authentication method of a specific token. For OATH, this is usually referred to as the OATH seed.
Domain A logical partitioning of configuration and operational keys in EPS to support a multi-tenant setup.
Enrollment The process of creating a token for a user within EPS so that credentials are generated or derived and propagated to back-end systems such as authentications servers. The enrollment step is a prerequisite of the provisioning step.
Ezio Mobile SDK The client side part of the Ezio Mobile solution consisting of an SDK that is used to build secure eBanking or mBanking applications on different mobile platforms.
Integration Plug-In Plug-in Java class in EPS using the public integration API to provision tokens to external systems
Provisioning The process of securely transporting user credentials from the EPS to the mobile device so that an application can provide authentication and signing services.
Seed A token key for OATH. The seed is normally randomly generated as opposed to a CAP device key which is derived.
Template File containing token details and configuration. When an enrollment is performed, a template name needs to be provided and the token will be generated accordingly.
Tenant Each IdCloud customer is enrolled as a tenant on the server. Each tenant’s data is isolated so that it is impossible to access the data of other tenants
Token A token is the Ezio Mobile’s representation of a user credentials. A token is enrolled in the Ezio Mobile EPS and later provisioned to Ezio Mobile SDK on the mobile device.
Token ID The unique identifier assigned to a token by EPS.
JSON Web Token A compact URL-safe means of representing claims to be transferred between two parties.
User The person performing banking operations by using an application built with the use of Ezio Mobile SDK.
User Token ID A unique per user ID for a token.
