Source code is compiled to byte-code, like Java. In addition to this, it encrypts the code with encryption key which is separated from source code and byte code. The final result would be the encrypted byte-code. When the program or the service is executed, it decrypts the code and executes it. The whole process is done in cloud so nobody could exploit the niche vulnerability. If an attacker tries to crack it, he or she should get the encryption key first. If the encryption key is stored in the deepest layer of the cloud, the attacker should try to break the cloud system first. It’s a good application of cyclic authentication which I mentioned in other posting here.

This model would be applied to the cloud database solution Cloudbean, which offers new DML(Data Manipulating Language) named C2QL as the security concern is one of the most highlighted issues in cloud system. The challenge is how to make the complexity of encryption higher not to be breached.

Today’s virtualization technology is brilliant. One great example is cloud computing. It reduces the cost incredibly by virtualizing physical machines to the cloud. The idea of on-demand option is a name of green for it saves electricity from power plants which uses fossil fuel and so emits carbonized materials. Manufacturing time table is simplified by adopting virtualization as well, in that way. How about online market? It virtualizes the real market on the web. That decreases the use of transporation which causes air-pollution. In the top of virtualization, there is a GREEN.

Virtualization has another effect. It cuts the total amount of task eventually. It seems like a negative one as less task cuts the workforce and somebody will lose the job. But you know? Money is also a kind of the result of virtualization. And that makes the gap between the rich and the poor though money is considered as a great invention in history. In my humble opinion, virtualization matters when it comes to the innovation. There are always pros and cons in healthy society. New idea may come from the discussion and development.

In the bottom line, virtualization is quite nice and cool. The future technology would hugely depend on the category that foreseers may already recognize the flow of. Do you have any idea on that area? Make it change the world!
