Communicating Secret Information without Secret Messages in Wireless Sensor Networks

Abstract

The problem of security in a sensor network has been researched mainly with methods derived from classical cryptography. With the advance of quantum computation and quantum cryptography, the problem of securing a sensor network with quantum means is immediate. The present paper adapts an existing quantum security protocol [1] to sensor networks. The contribution of the protocol is that it shares a secret message between two nodes of the sensor network, without showing in the environment any information about the content of the message. The information visible to other nodes and to the environment refers to array indices and to the reading strategy, but not to the values read. As each piece of secret information has a distinct public encoding, the protocol is equivalent to a one-time pad protocol. To exploit quantum properties, sensor nodes are endowed with coherent qubits, that can be read and set within the node. Additionally, there exists a central authority that manages the identity of the nodes and can perform quantum entanglement swapping.

Carving Secret Messages out of Public Information

Naya Nagy, Marius Nagy, Selim G. Akl

This study shows that secret information can be shared or passed from a sender to a receiver even if not encoded in a secret message. In the protocol designed in this study, no parts of the original secret information ever travel via communication channels between the source and the destination, no encoding/decoding key is ever used. The two communicating partners, Alice and Bob, are endowed with coherent qubits that can be read and set and keep their quantum values over time. Additionally, there exists a central authority that is capable of identifying Alice and Bob to share with each half of entangled qubit pairs. The central authority also performs entanglement swapping. Our protocol relies on the assumption that public information can be protected, an assumption present in all cryptographic protocols. Also any classical communication channel need not be authenticated. As each piece of secret information has a distinct public encoding, the protocol is equivalent to a one-time pad protocol.

Quantum communication in distributed wireless sensor networks

Jung-Shian Li, Ching‐Fang Yang

In the wireless sensor networks (WSNs), sensor nodes may be deployed in the hostile areas. The eavesdropper can intercept the messages in the public channel and the communication between the nodes is easily monitored. Furthermore, any malicious intermediate node can act as a legal receiver to alter the passing messages. Hence, message protection and sensor node identification become important issues in WSN. In this paper, we propose a novel scheme providing unconditional secure communication based on the quantum characteristics, including no-cloning and teleportation. We present a random EPR-pair allocation scheme that is designed to overcome the vulnerability caused by possible compromised nodes. EPR pairs are pre-assigned to sensor nodes randomly and the entangled qubits are used by the nodes with the quantum teleportation scheme to form a secure link. We also show a scheme on how to resist the man-in-the-middle attack. In the framework, the qubits are allocated to each node before deployment and the adversary is unable to create the duplicated nodes. Even if the malicious nodes are added to the network to falsify the messages transmitting in the public channel, the legal nodes can easily detect the fake nodes that have no entangled qubits and verify the counterfeit messages. In addition, we prove that one node sharing EPR pairs with a certain amount of neighbor nodes can teleport information to any node in the sensor network if there are sufficient EPR pairs in the qubits pool. The proposal shows that the distributed quantum wireless sensor network gains better security than classical wireless sensor network and centralized quantum wireless network.

Quantum Cryptography Using Various Reversible Quantum Logic Gates in WSNs

Syed Hassan Ahmed, Nadeem Javaid, Safdar Hussain Bouk +3 more

As sensor nodes are deployed anywhere in a wireless sensor network, hence their communication can be easily monitored. In these networks, message protection and node identification are very issues. Hence, security of large scale such networks requires efficient key distribution and management mechanisms. Quantum cryptography and particularly quantum key distribution is such a technique that allocates secure keys only for short distances. While not completely secure, it offers huge advantages over traditional methods by the use of entanglement swapping and quantum teleportation. Reversible logic gates like CNOT, Toffoli, Fredkin etc. are of basic importance in Quantum Computing. In our research, we adopted a EPR-pair allocation scheme in terms of these quantum gates to overcome the susceptibility caused by malicious nodes. As the qubits stored in a sensor node can be used only once and cannot be duplicated, hence risk of information leakage reduced even if the node are compromised.

Analysis of Key Management and Quantum Cryptography in Wireless Sensors Networks

Vijey Thayananthan

Key management and quantum cryptography (QC) are very interesting and challenging areas in wireless sensor networks (WSN). In order to make secure communications around WSN, communication between sensor nodes and base station to sensor node communication should be handled carefully. Today’s security around WSN needs efficient key management protocol and QC involved with quantum mathematical procedures and quantum physics [1]. According to the key management analysis, computational complexities of conventional and potential cryptography are very high. In order to avoid high complexity in key management, QC can be used because it is involved with quantum computation [4][5]. Quantum key distribution (QKD) is already established with laws of quantum mechanics influenced to quantum computations for some networks such as fiber optic, satellite based communication etc. Therefore, efficient approach of QC will be analyzed to manage the keys with maximum security and less complexity. Key management protocol [2][3] in wireless networks is influenced with authentication which uses symmetric or asymmetric cryptography. Authentication and entities in upper layers use public key cryptography [6]. In this paper, we propose an enhanced version of key management and QC for WSN. Thus, we modify authentication protocol between the access points and wireless sensor network with symmetric polynomial based on QC approach. In modern QC, there are possibilities for which quantum computation techniques allow to expand the bandwidth. It is another interesting area in QC because bandwidth expansion will increase the level of security in WSN

Secure Quantum Key Distribution Encryption method for Efficient Data Communication in Wireless Body Area Sensor Net-works

Y Sai Suguna, B Kavya Reddy, V Keerthi Durga +1 more

Wireless sensor networks has found its advancement in sensing the physiological parameters of human body through WBAN. Such nodes are either implanted or surface mounted on the human body in a particular position. The main purpose of these networks is to send the data generated by the wearable device outside the WLAN or the Internet. The BAN will continuously monitor the psychological changes like blood volume pressure (BVP), Brain signals etc. Uncertainty in the normal values will result in transmit all the information to the respective recipient to take required treatment. If an emergency is detected, the doctor instantly updates the patient’s health by sending a specific message. There is limited confidentiality, so the intruders will gather sensitive data. Public key cryptography can be used to create an unprotected communication channel. It also provides a convenient way to implement keys. This paper is focusing on a unique key generation technique called Quantum key distribution, which is used to create symmetric key method by using quantum properties of optics to transfer information from one Client to another in One-Time Pad manner. The special feature of the technique is to guarantee that the key cannot be intercepted during transmission without alerting the users to provide high authentication for received data.
