摘　　要：针对IoT-云架构中大数据的安全性问题,提出了一种基于多因子身份验证和轻量级密码技术的安全方案。该方案中,IoT设备分为敏感设备和不敏感设备,使用RC6和Fiestel加密方案对敏感设备生成的数据进行加密,使用高级加密标准(AES)加密方案对不敏感设备生成的非敏感数据进行加密;将敏感和非敏感数据分别保存在私有云和公有云中,以确保高度安全性。此外,还提出了多因子身份验证方法,以确保访问云数据的安全性。在NS3网络模拟器中实施了该云-IoT架构,实验结果表明,所提方案在计算时间、安全强度等性能方面优于对比方案。Aiming at the security of big data in IOT Cloud Architecture,a security scheme based on multi factor authentication and lightweight cryptography technology is proposed.In this scheme,IOT devices are divided into sensitive devices and insensitive devices.RC6 and Fiestel encryption schemes are used to encrypt the data generated by sensitive devices,and advanced encryption standard(AES)encryption scheme is used to encrypt the non sensitive data generated by insensitive devices;Save sensitive and non sensitive data in private cloud and public cloud respectively to ensure high security.In addition,a multi factor authentication method is proposed to ensure the security of accessing cloud data.The cloud IOT architecture is implemented in the NS3 network simulator.The experimental results show that the proposed scheme is superior to the comparison scheme in terms of computing time,security intensity and other performance.
