British researcher cracks crypto problem

His scheme lets computation be performed on encrypted data without the need to decrypt it first, which could be useful for calculations connected to electronic health records.

A British researcher has helped put into practice an encryption scheme that could better protect sensitive data while it is being used in systems such as health care computing.

The scheme involves fully homomorphic encryption, an approach that allows computation to be performed on encrypted data without the need to decrypt the data, according to Nigel Smart, professor of cryptology in the Department of Computer Science at the University of Bristol.

Last year, IBM researcher Craig Gentry came up with the first homomorphic scheme, which allowed simultaneous add and multiply operations on encrypted values, called ciphertexts.
