Symmetric-Key-Based Authentication among the Nodes in a Wireless Sensor and Actuator Network

Abstract

To enable today’s industrial automation, a significant number of sensors and actuators are required. In order to obtain trust and isolate faults in the data collected by this network, protection against authenticity fraud and nonrepudiation is essential. In this paper, we propose a very efficient symmetric-key-based security mechanism to establish authentication and nonrepudiation among all the nodes including the gateway in a distributed cooperative network, without communicating additional security parameters to establish different types of session keys. The solution also offers confidentiality and anonymity in case there are no malicious nodes. If at most one of the nodes is compromised, authentication and nonrepudiation still remain valid. Even if more nodes get compromised, the impact is limited. Therefore, the proposed method drastically differs from the classical group key management schemes, where one compromised node completely breaks the system. The proposed method is mainly based on a hash chain with multiple outputs defined at the gateway and shared with the other nodes in the network.

Multivariate Broadcast Encryption with Group Key Algorithm for Secured IoT

“…In all other terms, given the ubiquitous use of these devices and their ability to communicate with one another without the limited funding, data protection and identification are most pressing concerns for energy various measures. Traditional approaches for authenticated key agreements that use a key exchange protocol [18][19][20] really aren't appropriate again for architecture of the device system for various purposes: A need of significant processing burden even during administration of effective key methods is among the main factors, as is the overburdening of replying to every device queries independently.…”

Hybrid Authentication Using Node Trustworthy to Detect Vulnerable Nodes

“…Unfortunately, despite being the most effective resource for avoiding these types of attacks, a system based on a cryptographic system is not yet accessible in the research. The TESLA method [1] and its versions [23][24][25] are usually the most popular method for clustering with node authentication utilizing symmetric key cryptography. However, these systems rely on a hashing chain and disclose each chain's values in predetermined time intervals.…”
