Novel Framework for Secure Data Aggregation in Precision Agriculture with Extensive Energy Efficiency

Table 2

Comparison with security scheme.

Approaches	Advantage	Limitation
Prototyping [30]	Can resist deauthentication attack	Hardware resource inclusion is not considered
Rule-based attack resistance [31, 33]	Flexible formulation of attack-resisting rules	Attack specific solution
Software defined network [32]	Offer more intelligence	Cost-effectiveness is not assessed
Privacy preservation [34]	Ensure better data integrity and privacy	Computationally extensive algorithm
Blockchain [35, 36]	Robust security	Consumes large energy
Proposed	(i) Can handle multiple forms of attack and threats in PA; (ii) No sophisticated encryption is used; (iii) Multiple layers of security in each step; (iv) A higher degree of forward and backward secrecy; (v) Offers data security along with energy efficiency
