Contemporary information technology isn't adequate to secure the valuable information these systems are entrusted to manage, as recent security breaches at US corporations and government agencies demonstrate. There are two reasons for this. First, public and private networks, based on Ethernet and the TCP/IP protocol, weren't designed to protect information, but to make it easy to share information. Second, the architecture of the modern IT infrastructure was established long before cybercrime became the global nemesis that it is today, and therefore the issues of security and trust weren't well understood or taken into account. Before widespread adoption of the Internet, there was no means to generally interact with both public and private data centers throughout the world. Combine this global accessibility with the ability to provide remote access over the Internet, rather than just publish information as the Web was intended, and you have the makings of an information security disaster. Tamperproof computing platforms, or TPCPs, can help address the principal failings of contemporary IT, primarily the lack of means for adequately protecting encryption keys and for maintaining sustainable "chains of trust," rooted in a known trusted entity for software running on tamperproof hardware. Some have concluded from the lack of existence of such systems that TPCPs aren't feasible. While this may have been true in the past, the advent of hyperscale semiconductor integration and system-on-a-chip technologies now enable construction of TPCPs. Today, it is possible to build TPCPs based on tamperproof hardware and to create software capable of exploiting sustainable chains of trust. For more details : Motion Graphics Video
