Integrity Protecting and Privacy Preserving Data Aggregation Protocols in Wireless Sensor Networks: A Survey

Abstract

The data aggregation is a widely used energy-efficient mechanism in wireless sensor Networks (WSNs), by avoiding the redundant data transmitting to base station. The deployment of wireless communicating sensor nodes in the hostile or unattended environment causes attack more easily and the resource limited characteristics make the conventional security algorithms infeasible, hence protecting privacy and integrity during data aggregation is a challenging task. The privacy of a sensor data ensures, it is known only to itself and the integrity guarantees sensor data has not tampered during data aggregation. The Integrity Protecting Privacy preserving Data Aggregation (IPPDA) protocols ensures a robust and accurate results at the base station. This paper summarises on such IPPDA protocols during data aggregation

A novel secure biomedical data aggregation using fully homomorphic encryption in WSN

“…As an example, let h = -567. 23 In general, the range of the elements of a row vector corresponding to a positive or negative decimal number, is -9 to +9. A few numerical examples are shown in Table 3 for L = 6.…”

“…Let their equivalents row vectors be G and H each with size 1x(L+K). Append R1, S1 and R2, S2 to G and H respectively to get Q1 and Q2 as, (23) The size of Q1 as well as Q2 is 1x(L+K+2) = 1xn. (Note that n = L+K+2).…”

“…They have provided solutions for achieving low-complexity homomorphic operations for FHE, converging on the hardware implementation. In [19]- [23], authors have discussed on privacy preserving aggregation techniques for non-homomorphic methods. Whereas in our proposed research work, new privacy preserving method for fully homomorphic aggregation functions are discussed and is realized using software which can be scaled up effortlessly at low computational cost.…”

A survey and performance evaluation of decentralized aggregation schemes for autonomic management

“…Because of the emergence of numerous decentralized aggregation protocols, many studies have been performed in order to compare their performance [12][13][14][15][16] in the context of network management. Other surveys have been performed in the context of wireless sensor networks [17][18][19][20][21][22][23][24][25][26][27].…”

“…In the context of wireless sensor networks, some surveys [19,22,23,25,26] are out of the scope of this paper as they primarily focus on security and encryption schemes that can be embedded in aggregation protocols without discussing aggregation performances. The other surveys focus on aggregation protocol performance under resource consumption constraints [17,18,20,24,27].…”
