45496 并通过群组密钥协商解决角色与密钥映射关系中密钥更新与权限撤销等带来的安全问题。 Furthermore, in the proposed scheme, the group key agreement protocol was utilized to achieve rekeying and permission revocation.
45497 安全性分析表明所提角色对称加密算法和云数据安全去重方案是安全的， Finally,the security analysis shows that the proposed role-based symmetric encryption algorithm is provably secure under the standard model, and the deduplication scheme can meet the security requirements.
45498 性能分析和实验结果表明所提安全去重方案是高效的。 The performance analysis and experimental results indicate that the proposed scheme is effective and efficient.
45499 针对天地一体化网络中卫星和地面实体通信链路时延长、不稳定的问题，提出一种基于令牌的两方漫游认证方案。 Aiming at the problem of prolongation and instability of satellite and terrestrial physical communication link sin the space-earth integration network, a two-way token based roaming authentication scheme was proposed.
45500 该方案利用网络中卫星节点具有一定计算能力的特性，将用户认证过程从网络控制中心（NCC）提前到接入卫星， The scheme used the characteristics of the computing capability of the satellite nodes in the network to advance the user authentication process from the network control center (NCC) to the access satellite.
45501 由卫星直接检验 NCC 颁发的令牌来验证用户的身份； The satellite directly verified the token issued by the NCC to verify the user's identity.
45502 同时，基于单向累加器的令牌机制，实现了用户的动态加入、轻量级的用户自主业务定制和计费；并通过 Bloom Filter 的引入实现有效的用户撤销和恶意接入控制。 At the same time, the token mechanism based on the one-way accumulator achieved the user's dynamic join, lightweight user self-service customization and billing,and the introduction of BloomFilter enabled effective user revocation and malicious access management.
45503 和已有的方案相比，该方案在保证漫游认证的安全性同时，显著减少了认证和密钥协商过程的计算和通信开销。 Compared with the existing scheme, the scheme can guarantee the security of roaming authentication and significantly reduce the calculation and communication overhead of the authentication and key negotiation process.
45504 提出异构网络中基于负载传递的联合接纳控制（LJAC, load-transfer-based joint admission control）算法， A load-transfer-based joint admission control (LJAC) algorithm in heterogeneous networks was proposed.
45505 该算法基于负载均衡接纳用户的接入请求，在异构网络交叠覆盖区域引入业务的动态负载传递，同时考虑异构网络的布局以及垂直切换等因素的影响。 The access requirements of users were admitted based on load balancing, the dynamic load transfer of traffics in the overlap-ping coverage areas of heterogeneous networks were introduced, and the influence of such factors as the layout of heterogeneous networks and the vertical handoff was considered in the algorithm.
