Wireless sensor network (WSN, Wireless Sensor Network) is a kind of autonomous network with sensor nodes. It is different from traditional RFID system that the WSN is through the distribution of sensor nodes in different locations to monitor environmental conditions. The collected data from sensor nodes were sent back to the base station for further analysis and processing to compensate the shortage...
A gateway-oriented password-based authenticated key exchange (GPAKE) scheme allows a client to establish an authenticated session key with a gateway via the help of an authentication server, where the client has pre-shared a password with the server. The desirable security properties of a GPAKE include session key semantic security, key privacy against the server, and password guessing attacks resistance...
Mobile agent and its security are first introduced in this paper. Fundamental to the mentioned communication security properties are issues relating to the identification and authentication of sending and receiving parties. A security authentication scheme for mobile agent of multi domain is provided and a detail description is given in the paper. The scheme is based on identity-based public key cryptography,...
A Bluetooth ad hoc network can be formed by interconnecting piconets. The security of the process of Bluetooth scatternet formation is a major factor to guarantee the applications of Bluetooth network. Through the analysis of the characteristics of Bluetooth scatternet formation algorithm and Bluetooth's security architecture, this paper gives out a scheme for Bluetooth scatternet security based on...
RFID is a widely adopted technology in the enterprises for inventory checking and management. Due to the ubiquitous nature of RFID, attackers can easily launch attacks over wireless channel whenever there is a flaw on the RFID authentication protocol being used. A successful attack can imply a substantial loss in the enterprise and may trigger a series of problems. In this paper, we investigate a...
Since there is eavesdropping and MITM attack during establishing encryption key between two Bluetooth devices, a secure key agreement scheme is designed based on elliptic curves cryptography and interlock protocol. This scheme can defend two kinds of attacks mentioned above. It provides bidirectional authentication for two devices and key integrity verification by exchanging the keyspsila Hash-value...
In this paper, we present a simple, lightweight, but robust security protocol for resource-constrained communications. This protocol is based on the backward property of RC4 stream cipher and achieves data confidentiality, data authentication, data integrity, and data freshness with low overhead and simple operations. Furthermore, an RC4-based hash function for the generation of message authentication...
The fast growth of wireless networking has made data security an essential issue. Encryption mechanisms relying on a static key structure, such as WEP (802.11) and TKIP (802.1x), are vulnerable to key cracking via the capture of wireless packets. Although new standards have been developed to fill this gap, a stable security protocol has been lacking. In this paper, we present a lightweight and solid...
