一个盲公开可验证的矩阵乘积外包计算方案

基于可验证数据库,提出了支持盲公开可验证的矩阵乘积匿名外包计算方案,该方案满足对计算结果公开可验证,同时可以保护用户身份及数据的隐私,防止恶意云服务器的欺骗行为。给出的安全性分析说明了方案在随机预言机模型下是适应性选择消息安全的。方案使用摊销模型,以降低计算开销,并通过模拟实验证明,与已有方案相比本方案计算开销更小。

A blindly public verifiable outsourcing scheme for matrix multiplication

An outsourcing scheme for matrix multiplication in verifiable database is proposed. This scheme supports the blindly public verification, and protects identity privacy and data privacy for clients. This can prevent the servers malicious behavior. The security analysis proof shows that the proposed scheme is adaptive chosen-message security in the random oracle model. The scheme uses the amortized model to reduce the computational overhead. In addition, the resulos of simulated experiment show that the computational overhead of our scheme is smaller than the existing schemes.
