摘要
双线性对运算是公钥加密中较昂贵的密码学操作之一。外包计算可将大量复杂的运算外包给云服务器来完成,用户只需要简单的操作就可以获得较高的计算效率。因此,提出一种基于单个服务器的双线性对安全外包计算方案,用户仅需要执行少量模乘和点加操作,验证率可以达到90%以上,较以前方案更加安全高效、实际可用。
Bilinear pairing computation has been considered as one of the most expensive operations in the public key encryption. Throughout outsourced computation, large quantity and complex computation can be outsourced to the cloud server to perform and the users only need simple operations to obtain the great efficiency. It presents an efficient and secure out-sourcing algorithm for bilinear pairing based on one untrusted servers. Users only need to perform modular multiplication and point addition operations to achieve the checkability of at least 90%. It is argued that our algorithm be more efficient and practical than the previous one.
