The semi-structured form of web pages, coupled with the availability of business-relevant data, has led to the availability of several established products on the market for wrapping data from the Web.

Origins Of The Technology Wire Wrapping is a technology that has been with us for over fifty years, and is still going strong in various telecommunications and electronics applications. It was originally developed in the late 1940’s by Bell Labs in the U.S.; they needed to develop a new system of interconnection of the copper cabling in their local exchange facilities, also known as Central Off...

At SAC 2009, Gennaro and Halevi showed that a key wrapping scheme using a universal hash function and ECB mode (a HtECB scheme) is broken, and the security of a scheme based on a universal hash function and CBC mode (a HtCBC scheme) has been left as an open problem. In this paper, we first generalize classical notions of universal and uniform hash functions, and propose two new notions, where w...
