Security, a moving target in both philosophy and application, is what I am looking for in my research.
Insecured Operating Systems and Protocols must be redesigned and reimplemented. However, how could we promise that after the redesign and reimpementing, the system would become securer? The fact is that security experts seem always be busy in patching the new bugs and tracing the Intruders from the sea of log files. They have no time to think if something is wrong from the beginning, or sometimes they realize the points but they just be trapped in some details and cannot release themselves away. Who should assume the duty?
A common sense is that new technology bring great convenience to human beings, also raise up new security problems at the same time. Mobile computing, for instance, is a innovation of Client/Server model. But the paramount factor in deciding its application is security. Current running model of mobile code is so strict that the deeper and broader application is cut off. What's the face of the looser model?
With the advent of DDOS , distributed network attack and distributed network security have attracted many gifted hackers and security experts. How to divide and cooperate the work? How to get a good performance?
