Traditional security computing provides fixed security service capability

making it impossible to reconfigure the security system based on changes in the network environment and security needs.Therefore

its adaptive capacity is poor and its security management becomes complicated.Besides

the ratio of hardware reuse is low.Reconfigurable security computing provides a new method to improve the flexibility

adaptability and extensibility of the system.This paper describes the development of reconfigurable security computing

preliminarily studies on its connotation and significance

puts forward its concept model and discusses the key technology and its research status in detail.What's more

the development trend of reconfigurable secure computing is analyzed.Reconfigurable information security system integrates the new computing and information security technique.It is the inevitable development trend and will provide a broader application for information security technology.
