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.

说明：  20 世纪70 年代以来,人们从工业过程的特点出发,寻找对模型精度要求不高而同样能实现高质量控制性能的方法,预测控制就是在这种背景下发展起来的。预测控制技术最初由Richalet 和Cutler 提出[1 ] ,它最大程度地结合了工业实际的要求,综合效果好,已经在理论和应用方面取得了显著进展,各种预测控制算法不断地产生并得到发展。预测控制算法具有三大本质特征:预测模型、滚动优化和反馈校正[2 ] 。它是不断滚动的局部优化,而非全局最优。预测控制的特点:建模方便 采用非最小化描述的离散卷积和模型,信息冗余量大,有利于提高系统的鲁棒性 采用滚动优化策略,使模型失配、畸变、干扰等引起的不确定性及时得到弥补,从而得到较好的动态控制性能 可推广到有约束条件、大迟延、非最小相位以及非线性等过程,对模型精度要求不高,跟踪性能良好,更适应于复杂工业过程控制。 (err)
