A New Lightweight Database Encryption and Security Scheme for Internet-of-Things

Internet-of-Things (IoT) extends the power of Internet and bring tremendous opportunity to academia and industry. However the security and data privacy challenges become major obstacles for its adoption and deployment. To address these issues, an encryption and security scheme is proposed for a lightweight database which is suitable for embedded systems with limited storage and computing resources. The scheme encrypts data are in both storage and used memory. So it can prevent sensitive data leakage from untrusted applications, zero-day-vulnerability and malicious attacks for the lightweight database. The prototype of the proposed scheme was presented and the feasibility and effectiveness was evaluated. The experimental results demonstrate the scheme is practical and effective.
