My research in information theory is largely focused on the fundamental limits of secure communication. We address both the source coding and the channel coding side of this study. My group has been able to successfully develop a theory of optimal encoding of an informaiton signal when the level of security is measured by the amount of distortion that an eavesdropper must experience because they do not have the secret key. The mathematical tools needed to characterize the limits of compression and key usage in these settings are related to rate-distortion theory and require additional novel concepts as well.
