CERIAS Researcher Ninghui Li Receives ICICS Best Paper Award

Fri, January 05, 2007CERIAS Media Citings

CERIAS affiliates Ninghui Li and Mike Atallah were among the researchers whose projects were named "Best Paper" and "Best Student Paper" at the Eighth International Conference on Information and Communications Security (ICICS '06).

CERIAS researcher Dr. Ninghui Li was honored with the best paper award at the Eighth International Conference on Information and Communications Security (ICICS '06).

Prof. Ninghui Li and Dr. Jiangtao Li won the award for their paper, "A Construction for General and Efficient Oblivious Commitment Based Envelope Protocols." The paper presents a cryptographic protocol that enables efficient oblivious attribute-based access control. The protocol, called an oblivious commitment-based envelope (or OCBE) protocol, is executed between a resource owner and a requester. The OCBE protocol ensures that the requester gets access to a requested resource if and only if the access control policy set by the resource owner is satisfied by the requester's attributes, which are documented by digitally signed certificates. Furthermore, the resource owner learns nothing about the requester's attributes, not even whether they satisfy the policy or not. This apparently paradoxical property is achieved by having the resource owner send the resource in an encrypted form so that the requester can decrypt if and only if his or her certified attributes satisfy the resource owner's policy, and the resource owner does not learn whether the requester is able to decrypt or not. In this way, the protocol ensures that the resource owner's access control policy is enforced while protecting the requester's privacy.

Current and  former CERIAS researchers Dangfeng Yao, Keith Frikken, and Mike Atallah were involved in the winning submission for best student paper. The paper was entitled "Point-based Trust Define How Much Privacy is Worth."

The 2006 ICICS conference was held in Raleigh, North Carolina December 4-7. Awards were presented to only two of the 119 submissions.
