Biography

Dr. Jun Xu's current research focuses on developing new techniques to address the security problems in Internet infrastructure and applications (i.e., E-commerce), in particular Denial of Service (DoS). There are several related projects under this theme. One project is the concept development and practical design of a novel cryptographic primitive: a humanizer that can tell a human being from a computer with high confidence. With Dick Lipton and Irfan Essa, Xu is demonstrating that this primitive is extremely useful in a large number of security and E-commerce applications, including DoS.
