Ph.D. Student, University of ConnecticutQiang Tang is a Ph.D. candidate in the CSE department at University of Connecticut, under the supervision of Dr Aggelos Kiayias and Dr Alex Russell. He also paid several academic visits to (or interned at) the University of Athens, University of Wisconsin, Madison, and NTT R&D. Tang’s research interests are applied and theoretical cryptography and computer security in general. His recent works consider cryptology in the extreme cases, including new types of accountability problems which provide proactive deterrence when the key owner is malicious, and the formalization of the security of decoy systems (i.e. honey encryption schemes) when the key entropy is very low. He also revisited a couple of classic accountability problems and had contributions on graded distributed cryptography.
