Kabir, N., Kamal, S..  2020.  Secure Mobile Sensor Data Transfer using Asymmetric Cryptography Algorithms. 2020 International Conference on Cyber Warfare and Security (ICCWS). :1–6.
Mobile sensors are playing a vital role in various applications of a normal day life. Key size in securing data is an important issue to highlight in mobile sensor data transfer between a smart device and a data storage component. Such key size may affect memory storage and processing power of a mobile device. Therefore, we proposed a secure mobile sensor data transfer protocol called secure sensor protocol (SSP). SSP is based on Elliptic Curve Cryptography (ECC), which generates small size key in contrast to conventional asymmetric algorithms like RSA and Diffie Hellman. SSP receive values from light sensor and magnetic flux meter of a smart device. SSP encrypts mobile sensor data using ECC and afterwards it stores cipher information in MySQL database to receive remote data access. We compared the performance of the ECC with other existing asymmetric cryptography algorithms in terms of secure mobile sensor data transfer based on data encryption and decryption time, key size and encoded data size. In-addition, SSP shows better results than other cryptography algorithms in terms of secure mobile sensor data transfer.

Khatri, P..  2014.  Using identity and trust with key management for achieving security in Ad hoc Networks. Advance Computing Conference (IACC), 2014 IEEE International. :271-275.

Communication in Mobile Ad hoc network is done over a shared wireless channel with no Central Authority (CA) to monitor. Responsibility of maintaining the integrity and secrecy of data, nodes in the network are held responsible. To attain the goal of trusted communication in MANET (Mobile Ad hoc Network) lot of approaches using key management has been implemented. This work proposes a composite identity and trust based model (CIDT) which depends on public key, physical identity, and trust of a node which helps in secure data transfer over wireless channels. CIDT is a modified DSR routing protocol for achieving security. Trust Factor of a node along with its key pair and identity is used to authenticate a node in the network. Experience based trust factor (TF) of a node is used to decide the authenticity of a node. A valid certificate is generated for authentic node to carry out the communication in the network. Proposed method works well for self certification scheme of a node in the network.
