随着移动的设备的发展和普及以及人际社交性的增强，移动的社交网络变得越来越流行。随着社交数据量的大量增加和云计算技术的发展，移动的社交网络的架构逐渐向基于云的架构演进，即移动的客户端将数据发送到云，并使数据可以从客户端访问。云中的数据应该以安全的方式存储，以保护用户隐私并限制用户定义的数据共享。基于密文策略的属性加密（CP-ABE）被认为是一种很有前途的安全解决方案，可用于云移动的社交网络对敏感数据进行加密。然而，其密文大小和解密时间与访问结构中的属性数线性增长。为了减少移动的设备的计算开销，本文提出了一种新的外包解密和匹配然后解密CP-ABE算法（OM-CP-ABE），该算法首先将计算密集型双线性对运算外包给代理，然后对密文中匹配访问策略的属性集进行解密测试。实验性能评估表明，所提出的解决方案在计算，通信和存储方面的安全强度和效率。此外，我们的建设被证明是可重放的基于双线性Diffie-Hellman（DBDH）假设的标准模型的安全的密信攻击（RCCA）。
Mobile social network is becoming more and more popular with respect to the development and popularity of mobile devices and interpersonal sociality. As the amount of social data increases in a great deal and cloud computing techniques become developed, the architecture of mobile social network is evolved into cloud-based that mobile clients send data to the cloud and make data accessible from clients. The data in the cloud should be stored in a secure fashion to protect user privacy and restrict data sharing defined by users. Ciphertext-policy attribute-based encryption (CP-ABE) is currently considered to be a promising security solution for cloud-based mobile social network to encrypt the sensitive data. However, its ciphertext size and decryption time grow linearly with the attribute numbers in the access structure. In order to reduce the computing overhead held by the mobile devices, in this paper we propose a new Outsourcing decryption and Match-then-decrypt CP-ABE algorithm (OM-CP-ABE) which firstly outsources the computation-intensive bilinear pairing operations to a proxy, and secondly performs the decryption test on the attributes set matching access policy in ciphertexts. The experimental performance assessments show the security strength and efficiency of the proposed solution in terms of computation, communication, and storage. Also, our construction is proven to be replayable choosen-ciphertext attacks (RCCA) secure based on the decisional bilinear Diffie-Hellman (DBDH) assumption in the standard model.
