Hash Function Design Based on Hybrid Five-Neighborhood Cellular Automata and Sponge Functions

In today’s world of pervasive computing, all the devices have become smart. The need for securing these devices becomes a need of the hour. The traditional cryptographic algorithms will not be ideal for small devices, and this opens a new area of cryptography named lightweight cryptography, which focuses on the implementation of cryptographic algorithms in resource-constrained devices without compromise in security. Cryptographic hash functions enable detection of message tampering by adversaries. This paper proposes a lightweight hash function that makes use of sponge functions and higher radii hybrid cellular automata (CAs). The proposed hash function shows good cryptographic properties as well as collision resistance and serves as an ideal hash function for lightweight applications.

Embedded security in a pervasive world

Embedded systems have become an integral part of our everyday life. Devices like vehicles, household appliances, and cell phones are already equipped with embedded microcontrollers. The networking of the myriads of embedded devices gives rise to the brave new world of pervasive computing. Pervasive computing offers enormous advantages and opportunities for users and businesses through new applications, increased comfort, and cost reduction. One often overlooked aspect of pervasive computing, however, are new security threats. This article describes security issues in current and future pervasive security scenarios, ranging from privacy threats and unreliable products to loss of revenue. We also highlight the opportunities, such as new business models, which are enabled through strong embedded security solutions. Current research issues are also summarized. As case studies, we introduce security aspects in future automotive systems and in ad-hoc networks.

Beyond usability: the OoBE dynamics of mobile data services markets

With processors imbedded in appliances, cars, books, and other retail products, modern society has entered the world of pervasive computing. Yet few consumers are able to set up new digital devices and integrate them into everyday life. From this perspective, the data-enabled mobile phone leads the way. In many markets, mobile phones have a product life cycle of 12 months or less. Some subscribers are able to put their new phones to immediate and full use. For others, the learning curve is so steep that they move on to a replacement without having learned to exploit the functionality available in the first one. This work applies earlier findings by IMARC researchers in segmenting mobile data services (MDS) markets, interprets recent survey data, and synthesizes a model to guide design of the Out-of-the-Box Experience (OoBE) for mobile data subscribers. This integrative model can be applied across cultures to help service developers, facilitators and operators design, distribute and communicate new MDS to fulfill the demand side requirements of potential adopters, and to guide packaging design to improve user experiences during the early stages of use.

The button strikes back

This paper explores what has happened to hypermedia since the advent of the World Wide Web. We currently live in a world where access to the internet is dominated by Web browsers and search engines. The concept of hypermedia linking is at best added value and at worst almost irrelevant to most Web sites. But everyone who uses the Web is aware of the concept implicitly and accepts with ease the idea of clicking on a button to follow a link to another page. Search engines are the dominant means of finding information, but everyone is aware of their limitations. This is all set to change as we move into a world of pervasive computing and start to access the internet through small, hand-held devices. Agent technology will become the dominant means of building distributed information management systems. The paper argues that hypermedia technology will become more important in this world, although most users will be unaware of what software technology they are using as they navigate through global information spaces via highly personalised and adaptive environments.
