Performance of Additive Homomorphic EC-ElGamal Encryption for TinyPEDS
نویسندگان
چکیده
Data aggregation is a popular approach employed in wireless sensor networks (WSNs) to minimize data transmission and storage. With aggregation techniques, the monitored data is expressed in a condensed form: Therefore, instead of storing all data sensed by several nodes, the network stores a condensed value only such as the sum of these values. However, data aggregation becomes problematic when the data to be aggregated is encrypted. As a solution, we apply an additive homomorphic encryption scheme, namely the elliptic curve ElGamal (EC-ElGamal) cryptosystem, and present the performance results of our implementation for the prominent sensor platform MicaZ mote.

Asymmetric Homomorphic Encryption Transformation for Securing Distributed Data Storage in Wireless Sensor Networks
In asynchronous wireless sensor networks it is not possible to transmit the monitored data to an authorized recipient in real-time. Thus, the data needs to be stored within the network in distributed fashion. However, due to the resource constraints of the sensor nodes the amount of data to be stored and transmitted must be minimized. One popular technique for this is in-network data aggregatio...
متن کاملOptimized Implementation of Elliptic Curve Based Additive Homomorphic Encryption for Wireless Sensor Networks
When deploying wireless sensor networks (WSNs) in public environments it may become necessary to secure their data storage and transmission against possible attacks such as node-compromise and eavesdropping. The nodes feature only small computational and energy resources, thus requiring efficient algorithms. As a solution for this problem the TinyPEDS approach was proposed in [7], which utilize...

In this paper we find a secure routing protocol for computer networks, which finds minimum optimum path using homomorphic encryption schemes. We briefly look into the existing homomorphic encryption algorithms. We make use of ElGamal encryption, Elliptic Curve encryption and a privacy homomorphism, which exhibits the property of homomorphism in our new routing protocol. Elliptic curve exhibits ...
متن کاملA Homomorphic Crypto System for Electronic Election Schemes
This research investigates the applications of homomorphic encryption systems in electronic voting schemes. We make use of Paillier cryptosystem which exhibits additive homomorphic properties. The other homomorphic cryptosystems RSA and Elgamal are not considered, since they exhibit only multiplicative homomorphic property. Our proposed method increases the level of security when compared to El...
