Lightweight and Secure Session-Key Establishment Scheme in Smart Home Environments

Abstract

The proliferation of current wireless communications and information technologies have been altering humans lifestyle and social interactions-the next frontier is the smart home environments or spaces. A smart home consists of low capacity devices (e.g., sensors) and wireless networks, and therefore, all working together as a secure system that needs an adequate level of security. This paper introduces lightweight and secure session key establishment scheme for smart home environments. To establish trust among the network, every sensor and control unit uses a short authentication token and establishes a secure session key. The proposed scheme provides important security attributes including prevention of various popular attacks, such as denial-of-service and eavesdropping attacks. The preliminary evaluation and feasibility tests are demonstrated by the proof-of-concept implementation. In addition, the proposed scheme attains both computation efficiency and communication efficiency as compared with other schemes from the literature.

An enhanced security framework for home appliances in smart home

“…), and financial information are used. For the reason, security technology should be applied [7,[9][10][11]. This section describes the structure and security matters of smart devices in smart home, and the previous studies related to smart home security.…”

“…Since smartphones supported various activities, such as financial affairs, business affairs, and personal affairs, the security technology of smartphones has been developed. However, the smart home appliances for smart home fail to have security technology and get exposed to many attacks [7,9,10]. Therefore, this paper proposes the internal security framework for smart devices, which can be applied to smart home appliances as well as smartphones.…”

Access Control Protocol With Node Privacy in Wireless Sensor Networks

“…Here, E is the encryption algorithm (e.g., AES (advanced encryption standard) [25]), and T 1 is the current time-stamp of node U. The U then sends N, S U , G U , T 1, K idU to the C node.…”

“…Here, E denotes the identical encryption scheme (AES [25]) and T 2 is the current time-stamp of the C node. The C node sends M, G C , S C , T 2 to the node U.…”

“…5. Both the nodes' clocks are synchronized using [25]. Following the Section III-B, the node U initiates the broadcast as a sender, while the node C acts as a cell coordinator, as shown in Fig.…”
