MODELING AND ANALYSIS OF MOBILE TELEPHONY PROTOCOLS by Chunyu Tang A DISSERTATION Submitted to the Faculty of the Stevens Institute of Technology in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chunyu Tang, Candidate ADVISORY COMMITTEE David A. Naumann, Chairman Date Yingying Chen Date Daniel Duchamp Date Susanne Wetzel Date STEVENS INSTITUTE OF TECHNOLOGY Castle Point on Hudson Hoboken, NJ 07030 2013 c 2013, Chunyu Tang. All rights reserved. iii MODELING AND ANALYSIS OF MOBILE TELEPHONY PROTOCOLS ABSTRACT The GSM (2G), UMTS (3G), and LTE (4G) mobile telephony protocols are all in active use, giving rise to a number of interoperation situations. This poses serious challenges in ensuring authentication and other security properties. Analyzing the security of all possible interoperation scenarios by hand is, at best, tedious under- taking. Model checking techniques provide an effective way to automatically find vulnerabilities in or to prove the security properties of security protocols. Although the specifications address the interoperation cases between GSM and UMTS and the switching and mapping of established security context between LTE and previous technologies, there is not a comprehensive specification of which are the possible interoperation cases. Nor is there comprehensive specification of the procedures to establish security context (authentication and short-term keys) in the various interoperation scenarios. We systematically enumerate the cases, classifying them as allowed, disallowed, or uncertain with rationale based on detailed analysis of the specifications. We identify the authentication and key agreement procedure for each of the possible cases. We formally model the pure GSM, UMTS, LTE authentication protocols, as well as all the interoperation scenarios; we analyze their security, in the symbolic model of cryptography, using the tool ProVerif.

Multiparty Selection Ke Chen Department of Computer Science, University of Wisconsin–Milwaukee, WI, USA [email protected] Adrian Dumitrescu Department of Computer Science, University of Wisconsin–Milwaukee, WI, USA [email protected] Abstract Given a sequence A of n numbers and an integer (target) parameter 1 ≤ i ≤ n, the (exact) selection problem is that of finding the i-th smallest element in A. An element is said to be (i, j)-mediocre if it is neither among the top i nor among the bottom j elements of S. The approximate selection problem is that of finding an (i, j)-mediocre element for some given i, j; as such, this variant allows the algorithm to return any element in a prescribed range. In the first part, we revisit the selection problem in the two-party model introduced by Andrew Yao (1979) and then extend our study of exact selection to the multiparty model. In the second part, we deduce some communication complexity benefits that arise in approximate selection. In particular, we present a deterministic protocol for finding an approximate median among k players. 2012 ACM Subject Classification Theory of computation Keywords and phrases approximate selection, mediocre element, comparison algorithm, i-th order statistic, tournaments, quantiles, communication complexity Digital Object Identifier 10.4230/LIPIcs.ISAAC.2020.42 1 Introduction Given a sequence A of n numbers and an integer (selection) parameter 1 ≤ i ≤ n, the selection problem asks to find the i-th smallest element in A. If the n elements are distinct, the i-th smallest is larger than i − 1 elements of A and smaller than the other n − i elements of A.

COT 5407:Introduction to Algorithms Author and Copyright: Giri Narasimhan Florida International University Lecture 1: August 28, 2007. 1 Introduction The field of algorithms is the bedrock on which all of computer science rests. Would you jump into a business project without understanding what is in store for you, without know- ing what business strategies are needed, without understanding the nature of the market, and without evaluating the competition and the availability of skilled available workforce? In the same way, you should not undertake writing a program without thinking out a strat- egy (algorithm), without theoretically evaluating its performance (algorithm analysis), and without knowing what resources you will need and you have available. While there are broad principles of algorithm design, one of the the best ways to learn how to be an expert at designing good algorithms is to do an extensive survey of “case studies”. It provides you with a storehouse of strategies that have been useful for solving other problems. When posed with a new problem, the first step is to “model” your problem appropriately and cast it as a problem (or a variant) that has been previously studied or that can be easily solved. Often the problem is rather complex. In such cases, it is necessary to use general problem-solving techniques that one usually employs in modular programming. This involves breaking down the problem into smaller and easier subproblems. For each subproblem, it helps to start with a skeleton solution which is then refined and elaborated upon in a stepwise manner. Once a strategy or algorithm has been designed, it is important to think about several issues: why is it correct? does is solve all instances of the problem? is it the best possible strategy given the resource limitations and constraints? if not, what are the limits or bounds on the amount of resources used? are improved solutions possible? 2 History of Algorithms It is important for you to know the giants of the field, and the shoulders on which we all stand in order to see far.

Bit Barrier: Secure Multiparty Computation with a Static Adversary
Breaking the O(nm) Bit Barrier: Secure Multiparty Computation with a Static Adversary Varsha Dani Valerie King Mahnush Mohavedi University of New Mexico University of Victoria University of New Mexico Jared Saia University of New Mexico Abstract We describe scalable algorithms for secure multiparty computation (SMPC). We assume a synchronous message passing communication model, but unlike most related work, we do not assume the existence of a broadcast channel. Our main result holds for the case where there are n players, of which a 1=3 − fraction are controlled by an adversary, for any positive constant.p We describe a SMPC algorithm forp this model that requires each player to send ~ n+m ~ n+m O( n + n) messages and perform O( n + n) computations to compute any function f, where m is the size of a circuit to compute f. We also consider a model where all players are selfish but rational. In this model, we describe a Nash equilibrium protocol that solve SMPC ~ n+m ~ n+m and requires each player to send O( n ) messages and perform O( n ) computations. These results significantly improve over past results for SMPC which require each player to send a number of bits and perform a number of computations that is θ(nm). 1 Introduction In 1982, Andrew Yao posed a problem that has significantly impacted the weltanschauung of computer security research [22]. Two millionaires want to determine who is wealthiest; however, neither wants to reveal any additional information about their wealth. Can we design a protocol to allow both millionaires to determine who is wealthiest? This problem is an example of the celebrated secure multiparty computation (SMPC) problem.
