2223 (3)当新父密钥是对称密钥时，innerwrap 中的对称加密密钥以及 outerwrap 中的密钥种子如何在源 TPM 与目标 TPM 之间安全交换，《TPM-Rev-2.0-Part-1-Architecture-01.38》并没有给出具体的解决办法。不仅如此，该协议流程还非常复杂，也无法统一，容易导致复制密钥泄露。 (3)when the new parent key is a symmetric key, how will the symmetric encryption key and the seed exchange securely between the source TPM and the target TPM .
2224 针对以上问题，本文提出了基于 MAK(Migrate Authentication Key)和复制接口的新密钥迁移协议—MDKMP(Make Duplication Key Migration Protocol)。 To solve the above problems, a new key migration protocol M DM KP is proposed.
2225 MDKMP 采用两阶段迁移模式， The M DM KP uses a two-phase migra-tion mode.
2226 第一阶段将源 TPM 密钥迁移到目的 TPM 的 MAK 下， In the first phase, the key is migrated to the M AK of the destination TPM .
2227 第二阶段再将密钥迁移到新父密钥下。 In the second phase, the key is migrated to the new parent key.
2228 本文提出一种基于演进原则度量的软件架构持续演进效果评估方法(Software Architecture EvolutionPrinciples，SAEP)， In this paper, we propose software architecture evolution principles(SAEP)to evaluate the evolution effect of software architecture based on the measurements of evolution principles.
2229 首先该方法给出与软件架构演进相关的四个代表性的软件架构演进原则; In SAEP, we firstly propose four representativeprinciples for software architecture evolution.
2230 然后通过对这四个架构演进原则的度量结果评估软件架构的演进效果; Secondly, the evolution effect of software architecture is evaluated based on the measurement of architecture evolution principles.
2231 最后把本文的方法应用于 8 个代表性的开源项目，并分别进行有效性验证实验， Finally, eight representative open source projects are performed by experi-ments for verifying the effectiveness respectively.
2232 实验结果表明:无论是单个演进原则还是四个演进原则结合起来，均能有效反映软件架构演进效果的好坏。 The experimental results show that a single evolution principle or the com-bination of four evolution principles can effectively reflect the evolution effect of the software architecture.
