Breaking (and Fixing) Real World Crypto

Abstract

In recent years, new forms of communication between people and devices have revolutionized our daily lives. The Internet has become the leading platform for human interaction (e.g., social networks), commerce, information, and also control of physical devices (e.g., Internet of Things). This new connectivity creates new security and privacy risks for individual users and organizations. It also increases the complexity and diversity of the different security and cryptographic solutions we need to protect against increasingly sophisticated and motivated attackers. Designing and implementing a secure system is a very elusive process. One needs to clearly identify the security targets (e.g., maintaining the confidentiality of the messages or preventing access from non-authorized entities) as well as the adversarial capabilities.
In this talk, I will show how we can combine cryptanalytic techniques with various side-channels to break the security guarantees of real-world implementations of cryptographic protocols, and how novel solutions can help mitigate the root causes of these vulnerabilities.

Exciton and trions in Van der Waals materials and their dynamics under different non-uniform strain
Configurations

Abstract

In recent years, Van der Waals (2D) materials, have attracted increasing attention due to their distinctive physical properties. As layered materials, they have been considered for flexible electronics as they can sustain strain higher than 10% without breaking down, although they are only 1-3 atom thick. Their superior mechanical properties led to a renewed interest in the mechanics of thin membranes linked to condensed matter physics. In this talk we will show how we can apply non-uniform strain to a suspended Van der Waals material (WS2) and alter the dynamics of excitons and trions. Surprisingly, we find that as we increase the non-uniformity of the strain, we are able to convert the excitons into trions with almost 100% efficiency without any electrostatic gating. Our results explain inconsistencies in previous experiments and pave the way towards new types of optoelectronic devices.

PROVE - A framework for development process design

Avi Shaked
PhD Yoram Reich

The development of systems is becoming increasingly challenging with respect to the complexity of the system as well as to the large scale, collaborative and integrative nature of the development effort. The design of system development efforts is, therefore, considered an essential contributor to their success. Unfortunately, development process design remains an undisciplined domain, lacking applicable, research-proven tools as a design infrastructure. Accordingly, the resulting design artifacts – development process plans – are typically flawed, risking the success of development efforts.
In this research, we propose and validate a fit-for-purpose, model based design framework to support development process design, in a way which corresponds with its ontology and contributes to its rigor. First, we derive relevant domain ontology for development process design, revealing desirable characteristics of such design. We then combine these with pertinent aspects of process modeling, and discuss the inadequacy of existing modeling approaches for the domain. Then, we describe a new modeling framework we designed particularly for development process design. This framework – PROVE – comprises both domain specific modeling methodology and domain specific notation, and embodies adaptations of modern modeling concepts and usability features. Next, we report multiple, diverse case studies in which the new framework was employed. These case studies demonstrate PROVE as a valid, applicative modeling framework, which contributes to various aspects of development process design, including its communicability, consistency and reuse. We also use PROVE concepts to extend a general purpose modeling framework (OPM), increasing both the practical usability of the general purpose framework for process design and the rigor of the resulting process models.  After establishing PROVE as beneficial, we conclude by highlighting further potential in its integration with other domain specific perspective as well as by offering possible generalizations of our work with respect to the design and use of modeling frameworks.
