Giovanni Di Crescenzo
Senior Research Scientist, Telcordia Technologies, Piscataway, New Jersey

Giovanni Di Crescenzo is a senior research scientist at Telcordia Technologies. He received a Ph.D. in Computer Science and Engineering from the University of California San Diego, USA, (with a thesis on cryptography) and a Ph.D. in Applied Mathematics and Computer Science from the University of Naples, Italy (with a thesis on zero-knowledge proofs). His main research activity has been in various areas of Mathematics and Computer Science, including Computer/Network/Information Security, Cryptography, Computational Complexity, and Distributed Algorithms, where he has produced more than 90 scientific publications in major refereed conferences and journals, including 1 book, 1 book chapter and 3 proceedings of conferences or workshops for which he was a technical program chair. For his innovative research work, he has given more than 20 invited talks, and was awarded more than 10 prizes or patent applications, including the O-1 United States VISA for aliens of extraordinary ability in the field of science (given to Nobel Prize winners or individuals “showing sufficient evidence of being one of the small percentage who have arisen to the very top of the field of endeavor''). He regularly referees papers for the major conferences and journals in his areas of expertise and interacts with academia professors, sometimes helping with temporary mentoring of their PhD students. He has been involved in more than 15 research projects funded by government agencies (including DARPA, ARDA, DOT, ARL, AFRL, NSA) or commercial institutions in the area of security, telecommunication, telematics, and entertainment.



One cornerstone in the design of identity management architectures is a suitable solution to the entity authentication problem. In light of frequent criticisms to both the usability and security inadequacies of simple password schemes, both practitioners and researchers have advocated strengthening such schemes and using multi-factor entity authentication schemes. In this talk we review some recent results in which we attempted to obtain new solutions to the entity authentication problem, the common goal being that of achieving improved usability-security tradeoffs.
