Recently, Boneh, Dunworth, and Lipton (1996) described the potential use of
molecular computation in attacking the United States Data Encryption Stand
ard (DES), Here, we provide a description of such an attack using the stick
er model of molecular computation. Our analysis suggests that such an attac
k might be mounted on a tabletop machine using approximately a gram of DNA
and might succeed even in the presence of a large number of errors.
