Which of the following is a standard method to convey access rights in a digital environment?

The standard method to convey access rights in a digital environment is through a JSON Web Token (JWT). JWTs are compact, URL-safe means of representing claims to be transferred between two parties. These tokens are often used in authentication and information exchange scenarios. JWTs can be signed and optionally encrypted, which ensures that the access rights they convey are secure and tamper-proof. The encoded data within a JWT typically contains user identity and permissions, allowing resource servers to quickly verify access rights without the need for server-side session storage.

In contrast, while Protected EAP (PEAP), OpenID, and Lightweight EAP (LEAP) provide various authentication and identity management capabilities, they do not serve the primary function of conveying access rights in the same manner as JWT does. PEAP is used to create a secure authentication process over wireless networks, OpenID involves decentralized authentication for web services, and LEAP is a wireless LAN authentication protocol. Each of these methods has its applications, but they do not directly represent access rights like a JSON Web Token does.
