基于洋葱路由和ECC加密的Android-云计算安全访问机制

摘要

Android设备与云计算相结合能够解决移动终端资源不足的问题,针对Android设备与云端之间的安全访问问题,提出一种基于洋葱路由和ECC加密的Android-云计算系统安全访问机制.利用第二代洋葱路由(OR)机制,在Android用户和云终端之间构建一个多代理的匿名访问路径.利用椭圆曲线密码(ECC)加密洋葱路由中传输的数据,依靠椭圆曲线离散对数问题(ECDLP)确保数据传输的安全性.性能分析表明,该方案能够抵抗流量分析、暴力破解等攻击,保证了Android用户与云端存储系统之间的安全访问.%Android devices combined with cloud computing can solve mobile terminal resource shortage problem,for the issues that the Android devices and the cloud security access,a security access mechanism for Android-cloud computing based on onion routing and ECC encryption is proposed.The second generation of onion routing (OR) mechanism is used to construct an anonymous access path between Android users and cloud terminal by multi proxy.The Elliptic Curve Cryptography (ECC)encryption is used to encrypt the data transmission in onion routing,and ensure the security of data transmission according to the elliptic curve discrete logarithm problem (ECDLP).The performance analysis shows that this scheme can resist flow analysis,brute force attacks,and ensure the safe access between Android users and cloud storage system.
