Abstract: With the top-priority security, and giving attention to efficiency, application environment, run speed, resource consumption and agility, this paper proposes a secure system combined with two encryption methods: Rijndael and ECC from the phase of the cryptology, according to the actual problems a WaterBox faced to. Theoretic analysis and actual application manifest that the system is efficient, secure and practical. Great success has gained in the application of security product development, which proves that the system can meet the expected design aim.
