5314	首先对门限环签名方案进行改进，然后基于空间证明的共识机制提出了可删除的区块链。	Firstly, a threshold ring signature scheme was improved, and then a deletable blockchain scheme based on themechanism of proof of space (PoSpace) consensus was constructed.
5315	当某个区块数据过期或失效时，经大多数节点同意并签名后，可对该区块进行有效删除，并保持区块链的总体结构不变。	Most of nodes could sign and delete a block togetherwhen block data was overdue, and the overall structure of the blockchain was unchanged.
5316	在模拟环境中进行了仿真实验，结果表明，所提区块链方案在生成和删除区块时效率都很高，且不影响其他区块的存储和使用。	Several experiments in a simu-lated environment were executed, and the results show that the proposed blockchain scheme has high efficiency in gener-ating and delegating a block. Meanwhile, the deletion of a block doesn't influence the storage and use of other blocks.
5317	针对路网环境下 mix-zone 无法有效地实现属性进行隐藏或泛化和抵御伪装攻击的问题，基于属性泛化和同态加密，提出了一种秘态属性泛化的隐私保护方法。	In order to cope with the problems of resist the attack of user tracking with attributes and resist the disguisedattack in road networks, based on the conception of attribute generalization and the methods of homomorphic encryption,a privacy protection method to complete the calculation of attribute generalization in private state and achieve attributegeneralization was proposed.
5318	该方法通过同态加密，实现了秘密出价选择计算代理、秘密计算相似属性，并以相似属性完成属性泛化的整体处理。	The proposed method utilized the homomorphic encryption to achieve secret bidding selec-tion with an agent, and then utilize secure multi-party computation to calculate the similar attributes and achieve the at-tribute generalization in the end.
5319	通过属性泛化，解决了 mix-zone 可被攻击者利用属性追踪的问题，同时秘密计算的属性处理不会泄露任何信息给参与者，也防止伪装攻击者获得 mix-zone 中各用户的隐私信息。	With the help of fully attribute generalization, this method can solve the problem of us-ers can be tracked by the potential attributes, and at the same time the privacy calculation also does not reveal any infor-mation to participants, so this method can prevent the disguised attacker that obtains user's information in mix-zone.
5320	最后，通过安全性分析和实验验证分别在理论和实践这 2 个方面对所提算法的优势加以分析和比较。	At last, in order to demonstrate the superiority of the proposed method in both of academically and practicality, the securityanalysis and experimental verification are given, and the procedure of formulation verification and the result of experi-ment further substantiate the superiorities of the proposed method.
5321	针对云存储环境中密钥泄露、数据重复和完整性检验的问题，提出了一种支持密钥更新和密文数据去重的完整性审计方案。	For the problems of key-exposure, encrypted data duplication and integrity auditing in cloud data storage, apublic auditing scheme was proposed to support key update and encrypted data deduplication.
5322	所提方案利用布隆过滤器实现了密态数据的客户端去重，且每一次密钥更新能保证更新结果不能由其余时间周期的密钥猜测得到。	Utilizing Bloom filters, the proposed scheme could achieve client-side deduplication, and guaranteed that the key exposure in one time period didn'teffect the users' private key in other time periods.
5323	该方案首次解决了在支持密态数据去重的审计方案中密钥更新困难的问题。	The proposed scheme could solve the conflict between key-exposure resilient and encrypted data deduplication in public auditing scheme for the first time.
