This exposes a critical vulnerability in the SURF scheme, which is incremental as it corrects a prior oversight.
The paper identifies a serious flaw in a security assumption of the SURF scheme, showing it is easy to break in the required parameter regime, and includes the original version for reference.
There is a serious problem with one of the assumptions made in the security proof of the SURF scheme. This problem turns out to be easy in the regime of parameters needed for the SURF scheme to work. We give afterwards the old version of the paper for the reader's convenience.
