Smart objects are small devices with limited system resources, typically made to fulfill a single simple task. By connecting smart objects and thus forming an Internet of Things, the devices can interact with each other and their users and support a new range of applications.Due to the limitations of smart objects, common security mechanisms are not easily applicable. Small message sizes and the lack of processing power severely limit the devices' ability to perform cryptographic operations.This paper introduces a protocol for delegating client authentication and authorization in a constrained environment. The protocol describes how to establish a secure channel based on symmetric cryptography between resource-constrained nodes in a cross-domain setting. A resource-constrained node can use this protocol to delegate authentication of communication peers and management of authorization information to a trusted host with less severe limitations regarding processing power and memory.

“…In this way, the development of CoAP-based applications can benefit of existing knowledge and well-known, commonly used web technologies, because IoT objects and services offered by them can be exposed in the form of web services, fully compatible with REST principles [37]. Consequently, CoAP is anticipated as one of the major web transfer protocols in IoT in the near future [41].…”

This paper presents the Dynamic Adaptive Streaming over CoAP (DASCo), a solution for adaptive media streaming in the Internet of Things (IoT) environment. DASCo combines DASH (Dynamic Adaptive Streaming over HTTP), the widespread open standard for HTTP-compliant streaming, with Constrained Application Protocol (CoAP), the vendorindependent web transfer protocol designed for resource-constrained devices. The proposed solution uses DASH formats and mechanisms to make media segments available for consumers, and exploits CoAP to deliver media segments to consumers' applications. Consequently, the DASCo player offers native interoperability with IoT devices that are accessed via CoAP, thus it allows easy access to data collected by different sensors in order to enrich the multimedia services. In the paper we present an overview of constraints of default CoAP implementation with respect to media streaming, and propose guidelines for development of adaptive streaming service over CoAP. Moreover, we discuss the features of CoAP that can be investigated when designing an efficient adaptive algorithm for DASCo. Presented experimental results show poor performance of DASCo when default values of CoAP transmission parameters have been used. However, adjusting the parameters according to the network conditions considerably improves DASCo efficiency. Furthermore, in bad network conditions the enhanced DASCo is characterized by a more stable download rate compared to DASH. This feature is important in the context of dynamic media adaptation, since it allows an adaptation algorithm to better fit media bit rate with download conditions.

The 'Internet of Things' promises a society of smart objects which can work towards common purposes. For HCI, core questions relate to how people might become members of, or otherwise interact with, such a society. In this paper, we address these questions through a simple experiment in which people interact with smart objects, each of which has a specific sensingprocessing-communicating capability. In the experiment, objects had to be arranged such that their individual goals were satisfied. The human's role was partly to move the boxes and partly to ensure that all goals were met. The task was presented either as a rule discovery task (i.e., to deduce the goal of each object) or as a theme (pattern) discovery task (i.e., to deduce an appropriate arrangement of objects to satisfy the goals). In other words, the human task involved either a bottom-up analysis of goals or a topdown analysis of configuration. Differences between these conditions were found. The study presents a simple paradigm which, through modification of objects and rules, allows study of human interaction with smart objects in a goal-directed manner. The main conclusions relate to the ways in which people make sense of the smart objects.
