CMU Will Develop Architecture That Makes Internet Secure, Smart
The U.S. National Science Foundation (NSF) will fund a $7.1 million project led by Carnegie Mellon University researchers to develop a next-generation Internet architecture that addresses security and reliability shortcomings. The eXpressive Internet Architecture (XIA) Project will include innate security features to assure users of the legitimacy of downloaded documents and accessed websites, and help them locate desired content wherever it is most accessible.
The project is one of four NSF Future Internet Architecture programs that will pursue new ways to build a more trustworthy and robust Internet.
By making the numeric codes computers use to identify documents into hash values, XIA will enable the computer to mathematically ascertain whether the document it receives is consistent with its identifying hash value, or if it has been changed. The system also will use public key cryptography to determine the trustworthiness of websites through its Accountable Internet Protocol method.
In addition, XIA will enable users to address packets for the content they seek, rather than to a host site, which could substantially shrink network traffic by removing redundant downloads.
