full_form: JSON Web Signature
context: Requirement Name: JWS profile restriction Requirement Reference: TS 33.501 [3], clause 13.2.4.9 Requirement Description: SEPPs and IPXs follow the JWS profile as defined in TS 33.210 [8] with the restriction that they shall only use ES256 algorithm. Threat References: TR 33.926 [4], clause G.2.4.1, Use of weak JWS algorithm Test case: Test Name: TC_JWS_PROFILE_RESTRICTION Purpose: Verify that the SEPP under test is able to restrict the JWS profile to only use ES256 algorithm with IPX entities. Procedure and execution steps: Pre-Conditions: - Network product documentation of the SEPP under test, containing the information about the supported signature algorithms for JWS operation. - Test environment with a peer SEPP instance, which may be simulated. - Test environment with one node simulating an IPX-provider, which supports JWS operation among others. - The SEPP under test and the peer SEPP have mutually authenticated and already established N32-c connection. - The tester shall have
description: JSON Web Signature (JWS) is a technology used for digitally signing messages in JSON format. It ensures data integrity and authenticity by using cryptographic algorithms to create a unique signature for each message.
explanation: The text describes JWS as a technology that uses cryptographic algorithms for secure communication, placing it firmly within the category of technology.
