talk: Analysis of the Secure Remote Password (SRP) Protocol Using CPSA

The UMBC Cyber Defense Lab presents

Analysis of the Secure Remote Password (SRP) Protocol Using CPSA

Erin Lanus, UMBC Cyber Defense Lab

12:00–1:00pm, Friday, 6 September 2019, ITE 227, UMBC

Joint work with Alan Sherman, Richard Chang, Enis Golaszewski, Ryan Wnuk-Fink, Cyrus Bonyadi, Mario Costa, Moses Liskov, and Edward Zieglar

Secure Remote Password (SRP) is a widely deployed password authenticated key exchange (PAKE) protocol used in products such as 1Password and iCloud Keychain. As with other PAKE protocols, the two participants in SRP use knowledge of a pre-shared password to authenticate each other and establish a session key. I will explain the SRP protocol and security goals it seeks to achieve. I will demonstrate how to model the protocol using the Cryptographic Protocol Shapes Analyzer (CPSA) tool and present my analysis of the shapes produced by CPSA.

Erin Lanus earned her Ph.D. in computer science in May 2019 from Arizona State University. Dr. Lanus is currently conducting research with Professor Sherman’s Protocol Analysis Lab at UMBC. Her previous results include how to use state to enable CPSA to reason about time in forced-latency protocols. Her research also explored algorithmic approaches to constructing combinatorial arrays employed in interaction testing and the creation of a new type of array for attribute distribution to achieve anonymous authorization in attribute-based systems. In October she will begin as a research assistant professor at Virginia Tech’s Hume Center in Northern Virginia. email:

talk: Correlation analysis with small sample sizes, 2pm Tue 6/18, UMBC

Correlation analysis with small sample sizes

Peter Schreier, Univ. of Paderborn, Germany

2:00-3:00 Tuesday, 18 June 2019, ITE 325B, UMBC

Most common techniques for correlation analysis (e.g., canonical correlation analysis) require sufficiently large sample support, but in many applications only a limited number of samples are available. Correlation analysis with small sample sizes poses some unique challenges. In this talk, I will focus on the problem of determining the correlated components between two or more data sets when the number of samples from these data sets is extremely small. Applications are plentiful, and among them I will discuss the identification of weather patterns in climate science and analyzing the effects of extensive physical exercise on the autonomic nervous system.

talk: Security for Smart Cyber-Physical Systems, 12-1 5/3, ITE 227

talk: Data-driven Approach for Sustainable Smart Cities, 11am 5/6, ITE 459, UMBC

Information Systems Spring 2019 Distinguished Lecture on Sustainable Smart Cities

A Data-driven Approach for Sustainable Smart Cities

Prof. Prashant Shenoy, University of Massachusetts

11:00am Monday, 6 May 2019, ITE 459, UMBC

Recent technological advances have enabled deployments of pervasive sensing and actuation in our physical world, which has led to the emergence of cyber-physical systems where computing and sensing interact with the physical world and humans in unique and exciting ways. Such systems are increasingly being deployed in smart city domains such as energy, transportation, health, grids, and agriculture.

In this talk, I will argue that the rich and vast amounts of data generated by smart city applications necessitate a data-driven approach where AI and systems techniques are employed in a symbiotic manner to tackle smart city challenges. I will present two smart city applications from the energy domain as examples of such a symbiotic approach. I will first present WattHome, a city-scale machine-learning-based approach that can determine the least efficient buildings within a large city or region. I will present the results of a city-scale evaluation performed in collaboration with a local utility, where WattHome successfully identified causes of energy inefficiency for thousands of buildings. Second, I will present SolarClique, a sensor-less data-driven approach that is designed to detect anomalies in power generation of large number of existing solar sites without requiring any additional sensor instrumentation. I will conclude my talk by describing a number of open challenges in designing data-driven approaches for smart cities.

talk: The Evolution of Mobile Authentication, 1pm 4/30, ITE325, UMBC

The Evolution of Mobile Authentication

Prof. Keith Mayes, Royal Holloway University of London

1:00pm Tuesday 30 April 2019, ITE325, UMBC

Mobile communication is an essential part or modern life, however it is dependent on some fundamental security technologies. Critical amongst these technologies, is mobile authentication, the ability to identify valid users (and networks) and enable their secure usage of communication services. In the GSM standards and the 3GPP standards that evolved from them, the subscriber-side security has been founded on a removable, attack-resistant smart card known as a SIM (or USIM) card. The presentation explains how this situation came about, and how and why the protocols and algorithms have improved over time. It will cover some work by the author on a recent algorithm for 3GPP and then discuss how Machine-to-Machine and IoT considerations have led to new standards, which may herald the demise of the conventional removable SIM, in favour of an embedded eSIM.

talk: Using CPSA to Analyze Force-Latency Protocols, 12-1 4/19

UMBC Cyber Defense Lab

Using CPSA to Analyze Force-Latency Protocols

Dr. Edward Zieglar, National Security Agency

12-1 Friday, 19 April 19, ITE 227

Several cryptographic protocols have been proposed to address the Man-in-the-Middle attack without the prior exchange of keys. This talk will describe a formal analysis of one such protocol proposed by Zooko Wilcox-O’Hearn, the forced-latency defense against the chess grandmaster attack. Using the Cryptographic Protocol Shapes Analyzer (CPSA), we validate the security properties of the protocol through the novel use of CPSA’s state features to represent time. We also describe a small message space attack that highlights how assumptions made in protocol design can affect the security of a protocol in use, even for a protocol with proven security properties.

Edward Zieglar is a security researcher in the Research Directorate of the National Security Agency, where he concentrates on formal analysis and verification of cryptographic protocols and network security. He is also an adjunct professor at UMBC where he teaches courses in networking and network security. He received his master’s and doctoral degrees in computer science from UMBC.

talk: IPv6 and its Security Issues, 5:30 Mon. 4/22

IPv6 and its Security Issues

Neal Ziring, National Security Agency

5:30-6:45 Monday 22 April 2019, Math/Psych 101

CMSC 626 Guest Lecture — all are welcome to attend

In this talk, we will introduce the basics of IPv6 and some of the security issues associated with it. Specifically, we discuss the motivations, history and adoption of IPv6, and current status in the global Internet. We then detail the structure of an IPv6 address and the types of addresses used, and the conceptual model for address assignment in IPv6. The modes of deployment of IPv6, and understanding of how dual-stack mode works, is then provided. We then discuss the basic model for IPv6 control protocols, ICMPv6, and how they support low-level network operations. We then identify IPv6’s place in the network stack, and explain how that does, and does not, affect security. Several basic threats to IPv6 devices and networks will be identified as well as how common network security posture/hygiene can be affected by dual stack operation. Lastly, we identify some key concepts in secure use of IPv6, and discuss the concept of NAT and its use in IPv4 and why IPv6 does not use it.

talk: Why are memory-corruption bugs still a thing?, 10:30am Mon 4/8, ITE325

Why are memory-corruption bugs still a thing?

The challenges of securing software at an assembly level

Doug Britton
CTO, RunSafe Security Inc.

10:30-11:30 Monday, 8 April 2019, ITE346

Methods to chip away at the danger of memory-corruption bugs have been available for some time.  Why has the going-price of memory-corruption-based exploits not spiked?  If the methods were have a broad-based result in mitigating exploit vectors, there would be a reduction in supply, causing an increase in prices.  Also, there would be a reduction in the pool of people qualified to develop zero-days, allowing them to push the prices up.  The data suggest that prices have remained generally stable and attackers are able to move with impunity.  What are the challenges to large-scale adoption of memory-corruption based mitigation methods.
