Which authentication method requires signed requests for obtaining temporary credentials?

• A. OAuth 1.0 authentication
• B. JWT Bearer authentication
• C. Token authentication
• D. WSSE authentication

Answer: (A)

The authentication method that requires signed requests for obtaining temporary credentials is OAuth 1.0 authentication. This method is structured to enhance security by ensuring that requests are not only authenticated but also verified to ensure their integrity. In OAuth 1.0, the client must create a signature for each request that includes specific parameters such as the request URL, any parameters being sent, and a timestamp. This signature is then sent along with the request, allowing the server to verify it using the shared secret. This requirement for signed requests is crucial in the OAuth 1.0 framework because it mitigates the risk of man-in-the-middle attacks and ensures that only authorized clients can access the requested resources. The signed request mechanism reinforces trust and integrity during the process of obtaining temporary credentials, which can then be used for further actions without needing to send sensitive information repeatedly. Other methods mentioned, such as JWT Bearer, Token authentication, and WSSE authentication, do not necessarily require the same signed request approach to secure temporary credentials. Each has its own mechanisms for authentication and authorization, but they do not use the same signature-based verification system as OAuth 1.0 does.
