This disclosure provides a method for enabling or supporting simultaneous control of a plurality of TPMs. The plurality of TPMs comprises a first TPM and a second TPM. The method comprises obtaining from an application program an interface instance reference to an interface instance associated with the first TPM. The method comprises obtaining from the application program an application request. The application request comprises application request parameters and/or a function to be requested to the first TPM. The application request parameters comprise setup parameters indicative of the first TPM. The method comprises determining a type of the obtained application request. The type comprises a context initialization request or a function request. When it is determined that the type of the obtained application request corresponds to a context initialization request, the method comprises obtaining an instance context of the interface instance indicated by the interface instance reference and a trusted computing component, TCC, context associated with the application program; and transmitting the instance context and the trusted computing component context to the application program. When it is determined that the type of the obtained application request corresponds to a function request, the method comprises requesting, via the interface instance, the first TPM to perform the function, and/or computing an application response based on the application request parameters. The method comprises transmitting the application response to the application program. |
