4543 针对现有博弈模型难以有效建模网络攻防对抗动态连续特性的问题，提出了一种基于 Markov 时间博弈的移动目标防御最优策略选取方法。 For the problem that the existed game model was challenging to model the dynamic continuous characteristicsof network attack and defense confrontation effectively, a method based on Markov time game was proposed to select theoptimal strategy for moving target defense.
4544 在分析移动目标攻防对抗过程的基础上，构建了移动目标攻防策略集合，利用时间博弈刻画了单阶段移动目标防御过程的动态性，利用 Markov 决策过程描述了多阶段移动目标防御状态转化的随机性。 Based on the analysis of the attack and defense confrontation process ofmoving targets, the set of moving target attack and defense strategies was constructed. The dynamics of the single-stagemoving target defense process was described by time game. The randomness of multi-stage moving target defense statetransformation was described by Markov decision process.
4545 同时，将攻防双方对资源脆弱性抽象为对攻击面控制权的交替，从而有效保证了博弈模型的通用性。 At the same time, by abstracting the use of resource vulnera-bility by attack-defense participants as the alternation of the control of the attack surface, the versatility of the game mod-el was effectively guaranteed.
4546 在此基础上，分析并证明了均衡的存在性，设计了最优策略选取算法。 On this basis, the existence of equilibrium was analyzed and proved, and the optimal strat-egy selection algorithm was designed.
4547 最后，通过应用实例验证了所提模型的实用性和算法的有效性。 Finally, the practicality of the constructed model and the effectiveness of the algo-rithm are verified by an application example.
4548 为解决具有多个接收方时的消息安全传输问题，设计了一种基于编码的多接收方广义签密方案。 In order to solve the problem of secure transmission of messages with multiple receivers, a code-based gener-alized signcryption scheme with multi-receiver was designed.
4549 首先，设计了一个能够满足 IND-CCA2 安全的多次加密 McEliece 方案； Firstly, a multi-encrypted McEliece scheme that can meetthe security of IND-CCA2 was designed.
4550 然后，与 CFS 签名方案相结合设计了基于编码的多接收方签密与广义签密方案。 Combined with the CFS signature scheme, the multi-receiver signcryption andgeneralized signcryption scheme based on code were designed.
4551 安全性分析表明，该多接收方广义签密方案在机密性方面能够满足 IND-CCA2安全，在不可伪造性方面能够满足 EUF-CMA 安全。 The security analysis shows that the multi-receiver gener-alized signcryption scheme can meet the security of IND-CCA2 in terms of confidentiality and can meet EUF-CMA se-curity in terms of unforgeability.
4552 与其他类似多接收方签密方案相比，所提方案不包含指数运算、双线性对运算等操作，具有较高的计算效率和抗量子计算的优势。 Compared with other similar multi-receiver signcryption schemes, the proposed schemedoes not include exponential, bilinear pairing operations, etc., and has high computational efficiency and the advantage ofanti-quantum computing.
