There is a standard for token generation, it is JWT (JSON Web Token). Stateless: The session expiration time is set when the authentication token is released.
To understand statelessness, one must understand statefulness. In this article I am going to talk about two different ways of authentication: stateful and stateless authentication. ‘Stateful’ and ‘stateless’ have sort of a mutually dependent relationship when it comes to their definitions. Stateless authentication is great, but it takes time to implement and it contains some restrictions. The data is signed by the key of IdP to ensure the integrity and authority of the session data.Since the user session is stored on the client side, the server only have the capability to verify its validity by checking whether the payload and the signature match.It is obvious that they have opposite pros and cons. If you have learnt about networking, you may already heard about stateful and stateless, but in this article I am going to give these two adjectives other meanings.Stateful authentication is commonly used in many applications, especially for applications that do not require scalability too much.Stateful session is created on the backend side, and the corespondent session reference Id is sent to the client. What this function… If you are interested in the industrial design, you should definitely go for the specification of some authentication protocols. In a stateful protocol, if a c… In the following section I am going to share an improved version of stateless authentication that can eliminate some disadvantages.With this improvement, we can have the scalability and performance advantages of stateless authentication. Understanding Cloud Services - Stateful vs Stateless Applications Setting up hosting architecture is becoming more and more specialist all the time. All user data used to be stored server-side. Stateful: You can revoke the authentication session on the IdP anytime. We can break this down even further — consider binary, a language of 1’s and 0’s. When a client tries to access the application with a token, the application verifies token sign with a private key, check if the token is expired, retrieves all session data from the token and makes a decision if a client has access to the desired resource.Both approaches make sense, both have their advantages and disadvantages. To access the application as an identified client, the client uses the received authentication token.Authentication token could be Stateless and Stateful.After successful authentication, the application generates a random token to send back to the client then creates a client authenticated session in memory or an internal database. When we talk about computer systems, a “state” is simply the condition or quality of an entity at an instant in time, and to be stateful is to rely on these moments in time and to change the output given the determined inputs and state.If that’s unclear, don’t worry — it’s a hard concept to grasp, and doubly so with APIs. Stateless authentication easier to implement and scale, but stateful authentication is more secure and easier to manage.
Moreover, to change the output when taking the determined inputs and state into account. I simplify the examples here for better understanding. The application ensures that credentials are correct, generates authentication token and sends it back to the client. Stateless vs stateful authentication. In Stateless Protocol, there is no tight dependency between server and client.
The process described in OpenID Connect (OIDC) specification. To be stateful is to essentially rely on these moments in time. Authentication is a process exists in almost every application to Identify application client whether it is a user or other application.
At an instant in time, to be exact. Authentication token could be Stateless and Stateful.
In Stateful, the server thinks a client is just a dumb machine, while in Stateless, server things the client is an intelligent machine that doesn’t need to depend on any state on the server-side. Though we still cannot revoke the session data immediately, while we can forbid its lifetime extension by revoking the refresh token.In this article, I illustrate the ideas of stateful and stateless authentication.
I do not list concrete protocols for discussion since those protocols may contain many other security design that will blur out the focus between the differences between stateful and stateless authentication. In Stateful protocol, there is tight dependency between server and client. Authentication used to be stateful for a long period of time. To understand one, you need to understand the other.
