【Abstract】Security is critical to a wide range of current and future wireless data applications and services. This paper introduces the securitystrategy and the security implementation for ZigBee access to EPA network. Test shows that the implementation of the security strategy improves thereliability of the EPA network. These security device, which can be configured, can run steadily and meet the need of the industry control system.
