Do We Need a New Internet?

The Internet’s original designers never foresaw that the academic and military research network they created would one day bear the burden of carrying all the world’s communications and commerce. There was no one central control point and its designers wanted to make it possible for every network to exchange data with every other network. Little attention was given to security. Since then, there have been immense efforts to bolt on security, to little effect.
Bad enough that there is a growing belief among engineers and security experts that Internet security and privacy have become so maddeningly elusive that the only way to fix the problem is to start over.
