I have a
A40CR card. I want to make Security Domain, which was installed with the Delegated Management Privilege. My question is how to calculate the value of Token? I have the GP specification and I also checked it carefully. But i still don't know the calculation process. Can someone help me out?

For this question, you should have a careful look at card Specification Version 2.1.1: 7.7 Delegated Management Tokens and Receipts and DAP Verification "The algorithm for Token signatures is defined in Appendix B.3 - Public Key Cryptography Scheme 1 (PKCS#1)". The detailed process is decribed in spec. I think it's the best method to solve you question.
