摘要: 云计算外包越来越流行的同时也带来了新的安全问题和挑战:输入/输出数据的隐私性和结果的可验证性。本文围绕云计算环境下的安全矩阵行列式计算外包展开研究,构建一个适用于大矩阵行列式计算的可验证的安全云外包协议,在客户端将原始矩阵盲化加密后传送到云服务器端执行计算,云服务器将计算结果和验证值返回给客户端进行解密和验证。理论分析表明,在恶意云的安全模型下协议满足正确性、输入/输出私密性、高效性和结果可验证性。

Abstract: Computation outsourcing to the cloud has become a popular application. This computing paradigm brings in some new security concerns and challenges, such as input/output privacy and result verifiability. A protocol is designed to enable secure, robust cheating resistant, and efficient outsourcing of matrix determinant computation to a malicious cloud. Client encrypts the original matrix and then transfers it to cloud server to compute. Analysis shows that the proposed protocol is correct, secure, and robust cheating resistant. Extensive theoretical analysis also shows its high-efficiency.

Key words: cloud computation, secure computation outsource, determinant computation
