Message queuing brokers are a fundamental building block of the Internet of Things, commonly used to store and forward messages from publishing clients to subscribing clients. Often a single trusted broker offers secured (e.g. TLS) and unsecured connections but relays messages regardless of their inbound and outbound protection. Such mixed mode is facilitated for the sake of efficiency since TLS is quite a burden for MQTT implementations on class-0 IoT devices. Such a broker thus transparently… Expand

Secure Hybrid Publish-Subscribe Messaging Architecture
TLDR
This paper proposes a hybrid approach which secures the WAN and minimizes the delay on the LAN, and evaluates the Round Trip Time (RTT) with and without security enabled to determine the actual security overhead introduced for different computing platforms. Expand
A Distributed Security Mechanism for Resource-Constrained IoT Devices
TLDR
The real-time experimental evaluations have proven the applicability of the proposed mechanism pertaining to the security assurance and the consumed resources of the target IoT devices. Expand
Analysis of vulnerabilities in MQTT security using Shodan API and implementation of its countermeasures via authentication and ACLs
TLDR
This paper identifies various security loopholes in MQTT, using Shodan API and implementing an experimental setup on a Raspberry Pi as an MqTT Broker and python programs as publisher/subscriber clients to find the Broker was found to be immune to such attacks. Expand
Tighter Proofs for the SIGMA and TLS 1.3 Key Exchange Protocols
TLDR
New, fully-quantitative and concrete bounds that justify the SIGMA and TLS 1.3 key exchange protocols’ security levels are given, and it is proved that the strong Diffie–Hellman problem is as hard as solving discrete logarithms in the generic group model. Expand

TLDR
This paper implemented an elliptic curve based signature algorithm on a class 1 (following RFC 7228) constrained device (Zolertia Z1: 16-bit, MSP 430) and reached the design goal to keep the original data accessible by legacy parsers and signing does not break parsing. Expand
Automated Analysis and Verification of TLS 1.3: 0-RTT, Resumption and Delayed Authentication
TLDR
This work model and analyse revision 10 of the TLS 1.3 specification using the Tamarin prover, a tool for the automated analysis of security protocols, and shows the strict necessity of recent suggestions to include more information in the protocol's signature contents. Expand
Towards Privacy-Preserving Local Monitoring and Evaluation of Network Traffic from IoT Devices and Corresponding Mobile Phone Applications
TLDR
It is shown that a privacy-preserving and thus more data-protection (GDPR) compliant monitoring of IoT-related network traffic is possible – and how it will look is shown. Expand
Attack scenarios and security analysis of MQTT communication protocol in IoT system
TLDR
This paper discusses several reasons on why there are many IoT system that does not implement adequate security mechanism in MQTT protocol and demonstrates and analyzes how to attack this protocol easily using several attack scenarios. Expand
ECDSA on Things: IoT Integrity Protection in Practise
TLDR
It is shown that providing signed sensor data has little impact on the overall power consumption and hardware accelerated signing can further reduce the costs in terms of runtime, however, the differences were not significant. Expand
Identity management and its support of multilateral security
TLDR
The introduction to technologies for multilateral security and an architecture which enables multilaterally secure communication are described and problems and risks of identity management systems are discussed. Expand
