7.4 Application Binding Protocol Local third party evaluation [69] to an SP of a server application, and vice versa. If third party evaluation is not available then both client and server application's SPs can decide on any other adequate way of establishing trust in each other's application and its functionality. During this process, they decide the details of the ABP, such as how to perform an on-card verication and validation of applications. One possible way could be that the SP of a server application issues a certicate to a client application, and vice versa. The certicate hierarchy in the ABP is illustrated in gure 7.9. In the absence of CC evaluation, the certicate hierarchy shown in gure 7.9 will not include Common Criteria Certication Authority. The client application certicate has the hash value of the application. Similar contents will also be included in the server application's certicate that is issued by the SP of the client application. Basically, the enrolment process denes the restrictions and mechanisms (i.e. certicates, and cryptographic algorithms, etc.) that a client/server application's SPs agree on for the ABP. 7.4 Application Binding Protocol Local In this section, we begin the discussion by explaining the protocol prerequisite followed by the protocol description. 7.4.1 Protocol Prerequisites The prerequisites for the ABPL are listed below, and are an extension to the prerequisites listed in sections 4.7.1, 6.3.1 and 6.5.2 with exception of prerequisites PPR-8 to PPR-13. PPR-14 O-Card Relationship: The SPs of individual applications trust each other. The roles of the server and client are predened along with the privilege each client application is allocated. PPR-15 Certicated Application State: A client application either has a certicate that is issued by a third party evaluation authority or by the server application's SP. This certicate has the hash value of the secure (trusted) state of the client application as considered by the third party evaluation authority or the server application's SP. A similar situation applies for the server application's certicate that is issued by the client application's SP or third party evaluators. PPR-16 Trustworthy TEM: Applications trust the TEM and they have established a longterm shared secret key with it at the time of application installation (section 7.3.2). 174
7.4 Application Binding Protocol Local 7.4.2 Protocol Description The aim of the Application-Binding Protocol Local (ABPL) is to facilitate both the client and server applications on the same device to authenticate each other and verify their current states to be secure. The ABPL also enables applications to establish the application binding for future communications. The ABPL message description is as below: ABPL-1. CL : IMA CL = e KCL−T EM (CL i ||SE i ||N CL ) CL → F : CL i ||SE i ||Sign CL (CL i ||SE i ||N CL ||IMA CL )||CertS CL The request message contains the identities of the client and server applications together with a random number generated by the CL. In addition, the client application creates an IMA message (section 7.3.2) for the T EM. The client application signs the message and appends its certicate. ABPL-2. F → SE : CL i ||SE i ||Sign CL (CL i ||SE i ||N CL ||IMA CL )||CertS CL The rewall F receives the application-binding request and it will query the SE. If the server application wants to proceed with the ABPL, it forwards the message; otherwise, it registers an exception. ABPL-3. SE : IMA SE = e KSE−T EM (SE i ||CL i ||N SE ) SE → T EM : CL i ||SE i ||IMA CL ||IMA SE The SE veries the client's signature. If successful, it generates an IMA message for the CL. The SE then sends the message to the T EM that contains the identities and IMA messages of both the CL and SE. ABPL-4. T EM → SL : V RE CL = e KCL−T EM (h(SE)||K t SE−CL ||N CL + 1) T EM → SE : V RE SE = e KSE−T EM (h(CL)||K t SE−CL ||N SE + 1) The T EM veries the IMA messages from both the CL and SE. Then it will calculate the hash value of the SE, encrypt it with the shared key K CL−T EM and send it to the CL. Similarly, the TEM will calculate the hash value of the CL, encrypt it with the shared key K SE−T EM and send it to the SE. The encrypted messages also contain a session key generated by the T EM; this key is valid only during the ABPL run. ABPL-5. SE : skm = e K t SE−CL (e SE−CL ||N CL + 2||N SE ) SE : au = e KSE−CL (AP ||OR||N CL ||N SE ) SE : tc = Sign SE (SE i ||CL i ||N SE ||au) SE → CL : SE i ||CL i ||IMA CL ||skm||tc||CertS SE 175
