Special Issue Information

Dear Colleagues,

The advancement of smart devices, such as smart sensors, smart healthcare systems, and wearable devices has great impacts on human life and industry. Millions of smart devices are connected and communicated to deliver a lot of data related to humans, devices, and communications, but they are at risk of various attacks. The security of the Internet of Things (IoT) is the most significant urgent task to build a trustworthy and dependable infrastructure for IoT. This Special Issue aims to present various security solutions using innovative emerging technologies including blockchain, artificial intelligence, machine learning, and software-defined networking. This Special Issue is addressed to all types of security issues in IoT, such as device security, privacy, side-channel attacks, communication vulnerability, identity management, access control, and data security. Topics of interest include but are not limited to:

  • AI and ML/DL techniques for securing IoT;
  • Cyber threats and incident analysis in IoT;
  • Blockchain for IoT security;
  • Intrusion and anomaly detection techniques for IoT;
  • Secure protocol designs and new theory for IoT;
  • Lightweight cryptographic solutions for IoT;
  • Access control and identity management for IoT;
  • Device security and malware for IoT.

As network attacks are constantly and dramatically evolving, demonstrating new patterns, intelligent Network Intrusion Detection Systems (NIDS), using deep-learning techniques, have been actively studied to tackle these problems. Recently, various autoencoders have been used for NIDS in order to accurately and promptly detect unknown types of attacks (i.e., zero-day attacks) and also alleviate the burden of the laborious labeling task. Although the autoencoders are effective in detecting unknown types of attacks, it takes tremendous time and effort to find the optimal model architecture and hyperparameter settings of the autoencoders that result in the best detection performance. This can be an obstacle that hinders practical applications of autoencoder-based NIDS. To address this challenge, we rigorously study autoencoders using the benchmark datasets, NSL-KDD, IoTID20, and N-BaIoT. We evaluate multiple combinations of different model structures and latent sizes, using a simple autoencoder model. The results indicate that the latent size of an autoencoder model can have a significant impact on the IDS performance. Full article

Recently, as Internet of Things systems have been introduced to facilitate diagnosis and treatment in healthcare and medical environments, there are many issues concerning threats to these systems’ security. For instance, if a key used for encryption is lost or corrupted, then ciphertexts produced with this key cannot be decrypted any more. Hence, this paper presents two schemes for key recovery systems that can recover the lost or the corrupted keys of an Internet of Medical Things. In our proposal, when the key used for the ciphertext is needed, this key is obtained from a Key Recovery Field present in the cyphertext. Thus, the recovered key will allow decrypting the ciphertext. However, there are threats to this proposal, including the case of the Key Recovery Field being forged or altered by a malicious user and the possibility of collusion among participating entities (Medical Institution, Key Recovery Auditor, and Key Recovery Center) which can interpret the Key Recovery Field and abuse their authority to gain access to the data. To prevent these threats, two schemes are proposed. The first one enhances the security of a multi-agent key recovery system by providing the Key Recovery Field with efficient integrity and non-repudiation functions, and the second one provides a proxy re-encryption function resistant to collusion attacks against the key recovery system.
