说明：  This paper analyzes the cryptography scheme of the Trust Platform Model(TPM). The focus of the discussion would be the comparison of elliptic curve cryptography and the nowadays widely used 2048-bit RSA in evaluating which would be better suited to be used on TPM. A TPM implementation scheme based on ECC is proposed, which includes encryption and decryption schemes, signature and verification scheme, key agreement scheme. Corresponding examples of TPM commands would also be given.

继承、多继承、虚继承的使用！ 如果要想使一个公共基类在派生类中只产生一个基类子对象，则必须将这个基类设定为虚基类。-inheritance, multiple inheritance, the use of virtual inheritance! If we want to make a public base class in the derived class only have a base class Object son, they would have to set the base class for virtual base class.
