46426 大大减少传统策略更新中的计算和通信开销。经安全性分析证明，方案在标准模型下满足自适应选择明文攻击安全。 Compared to the existing related schemes, the size of ciphertext and users’secret key is reduced and can significantly reduce the computation and communication costs of updating ciphertext. It is more effective in the practical application.
46427 通过对比，用户私钥和密文长度都有所减少，密文更新交给云服务器完成，降低了数据拥有者的工作量，更加贴近实际应用。 In order to guarantee the users’ privacy in the process of making friends in the mobile social networks, a new scheme of proxy re-encryption privacy protection in the cross-domain environment was introduced.
46428 在移动社交网络中，为保证交友过程中的用户隐私，提出跨域环境下的代理重加密交友隐私保护方案。 The scheme employed the cross-domain multi-authority to sharing secret keys, so as to realize the access and shave of the cross-domain users data.
46429 利用跨域多授权中心共享密钥，实现了跨域用户数据的互相访问与共享； And the secret keys of users’ attributes were re-encrypted, based on the technology of the proxy re-encryption and attribute encryption, to achieve the friends matching under the conditions of extending the access policy.
46430 利用代理重加密与属性加密技术，对用户属性密钥进行重新加密，实现了以扩充交友访问策略条件的交友匹配；利用用户隐私密文文件与密钥分离技术，增强了用户数据的隐私性。 Meanwhile,in purpose of enhancing the privacy of users’ data, the technology which contained the separation of users’ privacy ciphertext and secret keys was adopted.
46431 解决了现有方案中存在的用户数据不能跨域跨云共享、交友过少匹配及用户下线不能交友的问题。 Based on that, problems in the existing system such as user data’s inability to be shared cross-cloud, less matching during the process of making friends and users’ inability to make friends when offline had been addressed.
46432 安全和实验分析表明，方案可以达到选择明文攻击（CPA, chosen plaintext attack）安全，保证交友用户的隐私不被泄露，并且比现有方案更有效。 Security and experimental analysis show that this scheme can achieve chosen plaintext attack (CPA)security, ensure the privacy of friend discovery, and that is more effective than existing solutions.
46433 物理层安全技术可以有效地对抗窃听行为，提高主链路传输的可靠性。 Physical-layer security could be used to effectively combat eavesdroppers and the transmission reliability of the main link could be improved.
46434 考虑存在多个窃听攻击的无线中继网络，且信源到目的端的直传链路始终存在，中继节点和窃听节点在转发数据时均采用解码转发方式，提出了基于多窃听协作的最佳中继选择方案； A wireless relay network with multiple both decode and forward eavesdroppers and re-lays were considered, in the presence of the link from source to destination.
46435 推导了非中继传输系统和最佳中继传输系统的中断概率和截获概率表达式； A best relay selection scheme based on multi-eavesdropper’s cooperation was proposed, and the outage probability and the intercept probability was deduced under both schemes without relay and with best relay.
