TL;DR: An overview of the network architecture and features of M2M communications in 3GPP are provided, and potential issues on the air interface are identified, including physical layer transmissions, the random access procedure, and radio resources allocation supporting the most critical QoS provisioning.
Abstract: To enable full mechanical automation where each smart device can play multiple roles among sensor, decision maker, and action executor, it is essential to construct scrupulous connections among all devices. Machine-to-machine communications thus emerge to achieve ubiquitous communications among all devices. With the merit of providing higher-layer connections, scenarios of 3GPP have been regarded as the promising solution facilitating M2M communications, which is being standardized as an emphatic application to be supported by LTE-Advanced. However, distinct features in M2M communications create diverse challenges from those in human-to-human communications. To deeply understand M2M communications in 3GPP, in this article, we provide an overview of the network architecture and features of M2M communications in 3GPP, and identify potential issues on the air interface, including physical layer transmissions, the random access procedure, and radio resources allocation supporting the most critical QoS provisioning. An effective solution is further proposed to provide QoS guarantees to facilitate M2M applications with inviolable hard timing constraints.

TL;DR: This paper proposes a security framework that integrates the blockchain technology with smart devices to provide a secure communication platform in a smart city.
Abstract: A smart city uses information technology to integrate and manage physical, social, and business infrastructures in order to provide better services to its dwellers while ensuring efficient and optimal utilization of available resources. With the proliferation of technologies such as Internet of Things (IoT), cloud computing, and interconnected networks, smart cities can deliver innovative solutions and more direct interaction and collaboration between citizens and the local government. Despite a number of potential benefits, digital disruption poses many challenges related to information security and privacy. This paper proposes a security framework that integrates the blockchain technology with smart devices to provide a secure communication platform in a smart city.

TL;DR: This work created a system where sensors communicate with a smart device that calls smart contracts and writes records of all events on the blockchain, which would support real-time patient monitoring and medical interventions and automate the delivery of notifications to all involved parties in a HIPAA compliant manner.
Abstract: As Internet of Things (IoT) devices and other remote patient monitoring systems increase in popularity, security concerns about the transfer and logging of data transactions arise. In order to handle the protected health information (PHI) generated by these devices, we propose utilizing blockchain-based smart contracts to facilitate secure analysis and management of medical sensors. Using a private blockchain based on the Ethereum protocol, we created a system where the sensors communicate with a smart device that calls smart contracts and writes records of all events on the blockchain. This smart contract system would support real-time patient monitoring and medical interventions by sending notifications to patients and medical professionals, while also maintaining a secure record of who has initiated these activities. This would resolve many security vulnerabilities associated with remote patient monitoring and automate the delivery of notifications to all involved parties in a HIPAA compliant manner.

TL;DR: This paper presents SOCRADES, an integration architecture that can serve the requirements of future manufacturing, and provides generic components upon which sophisticated production processes can be modelled.
Abstract: On the one hand, enterprises manufacturing any kinds of goods require agile production technology to be able to fully accommodate their customers' demand for flexibility. On the other hand, Smart Objects, such as networked intelligent machines or tagged raw materials, exhibit ever increasing capabilities, up to the point where they offer their smart behaviour as web services. The two trends towards higher flexibility and more capable objects will lead to a service-oriented infrastructure where complex processes will span over all types of systems -- from the backend enterprise system down to the Smart Objects. To fully support this, we present SOCRADES, an integration architecture that can serve the requirements of future manufacturing. SOCRADES provides generic components upon which sophisticated production processes can be modelled. In this paper we in particular give a list of requirements, the design, and the reference implementation of that integration architecture.

Abstract: Techniques for simplifying an authentication process from the viewpoint of a user while providing improved security to the many users currently employing no or weak security techniques. In logging into a web site hosted by a web server, a session begins by a user connecting and logging in with a device, such as a personal computer. Rather than a user name and password approach which is presently typical, the personal computer communicates with another user device, such as a smart phone. In one approach, an encoded acoustic signal is employed for this communication. The smart phone securely communicates with an authentication server which informs the web server whether the user has been authenticated or not.
