Towards the Model-Driven Engineering of Secure yet Safe Embedded Systems
We introduce SysML-Sec, a SysML-based Model-Driven Engineering environment
aimed at fostering the collaboration between system designers and security
experts at all methodological stages of the development of an embedded system.
A central issue in the design of an embedded system is the definition of the
hardware/software partitioning of the architecture of the system, which should
take place as early as possible. SysML-Sec aims to extend the relevance of this
analysis through the integration of security requirements and threats. In
particular, we propose an agile methodology whose aim is to assess early on the
impact of the security requirements and of the security mechanisms designed to
satisfy them over the safety of the system. Security concerns are captured in a
component-centric manner through existing SysML diagrams with only minimal
extensions. After the requirements captured are derived into security and
cryptographic mechanisms, security properties can be formally verified over
this design. To perform the latter, model transformation techniques are
implemented in the SysML-Sec toolchain in order to derive a ProVerif
specification from the SysML models. An automotive firmware flashing procedure
serves as a guiding example throughout our presentation.Comment: In Proceedings GraMSec 2014, arXiv:1404.163
KLEIN: A New Family of Lightweight Block Ciphers
Resource-efficient cryptographic primitives become fundamental for realizing both security and efficiency in embedded systems like RFID tags and sensor nodes. Among those primitives, lightweight block cipher plays a major role as a building block for security protocols. In this paper, we describe a new family of lightweight block ciphers named KLEIN, which is designed for resource-constrained devices such as wireless sensors and RFID tags. Compared to the related proposals, KLEIN has advantage in the software performance on legacy sensor platforms, while in the same time its hardware implementation can also be compact
Practices of Using Blockchain Technology in ICT under the Digitalization of the World Economy
Abstract. Pursuing the purpose of effective functioning in today's conditions, the business is forced to transform rapidly, to modernize at all levels. The world
is changing, erasing the limits of its certainty. Companies need quality transformations and strategies that are effective in the face of rapid change towards
"deep" digitization. Massive corporate management systems increasingly need the flexibility to keep pace with change. And companies with an innovative culture
are more in need of creative tasks than implementing detailed regulations.
In the post-industrial time of digital economy, issues related to the development
of the information sphere, the media and communications, the usage of modern
information systems to develop the economy and stabilize social development
as a whole, come first. The basic principles of practical application of Blockchain
are investigated in the work. The stages of development of Blockchain
technology, the stages of development of Blockchain technologies by time, the
application of distributed registry technology in Blockchain applications, the
principles of construction and operation of Blockchain have been specified. The
benefits of using NEM for business are substantiated and the components of
Proxima X technology, protocols and service layers, on-line and off-line protocols,
decentralized applications are exposed
