Three works will be described. In the first we present reactive secret sharing, that changes the secret according to unbounded sequence of common inputs, where no communication among the (dynamic set of) participants is allowed, we present a fully secure solution for simple functions but somewhat non secure solution for any function.. In the second work dynamic on-going multiparty computation, in which we consider the case of dynamic group of participants that should not know the sequence of inputs of the others, as well as should not know the function performed on the inputs. In the last work we consider the case of infinite execution with no communication among the participants where we prove that any automaton can be executed in a fully secure fashion, the construction is based on Krohn-Rhodes decomposition technique.

Joint works with Limor Lahiani, Moti Yung, Juan Garay, Niv Gilboa and Vladimir Kolesnikov

bio: Shlomi Dolev received his B.Sc. in Engineering and B.A. in Computer Science in 1984 and 1985, and his M.Sc. and D.Sc. in computer Science in 1990 and 1992 from the Technion Israel Institute of Technology. From 1992 to 1995 he was at Texas A&M University postdoc of Jennifer Welch. In 1995 he joined the Department of Mathematics and Computer Science at Ben-Gurion University where he is now a full professor and the dean of natural sciences.

He was a visiting researcher/professor at MIT, DIMACS, and LRI, for several periods during summers. Shlomi is the author of the book "self-stabilization" published by the MIT Press. He published two hundreds journal and conference scientific articles, and patents. Shlomi served in the program committee of more than 60 conferences including: the ACM Symposium on Principles of Distributed Computing, and the International Symposium on DIStributed Computing. He is an associate editor of the IEEE Transactions on Computers, the AIAA Journal of Aerospace Computing, Information and Communication and a guest editor of the Distributed Computing Journal and the Theoretical Computer Science Journal. His research grants include IBM faculty awards, Intel academic grants, Verisign, ISF, US Airforce, EU and NSF grants.

Shlomi is the founding chair of the computer science department at Ben-Gurion University, where he now holds the Rita Altura trust chair in computer science. His current research interests include distributed computing, distributed systems, security and cryptography and communication networks; in particular the self-stabilization property of such systems. Recently, he is involved in optical computing research.
