A pair of university researchers are presenting a system which could greatly
advance the use of cryptography in computing.
Bristol University computer science Professor Nigel Smart and Dr Frederik
Vercauteren from Belgium’s Katholieke University Leuven are planning to present
a paper which outlines a scheme for handling and computing encrypted content.
The scheme outlined in the paper, say the researchers, improves on a 2009
encryption scheme from IBM which allows for processing "add" and "multiply"
functions on encrypted data ciphertexts.
The researchers said that the paper could push forward efforts to develop a
practical system which computes fully encrypted data.
