Research Experience

Graduate Work

My work focuses on security and energy efficiency in wireless multihop networks, particularly mesh networks. In the security domain, I proposed a certificateless group key agreement protocol which is well suited for wireless mesh networks. The proposed protocol is secure against several attacks under the modified Bilinear Inverse Diffie-Hellman (mBIDH) problem assumption and the Elliptic Curve Discrete Logarithm (ECDL) problem assumption. In the energy efficiency domain, the proposed protocol adopts an asymmetric computation technique to shift the computational burden to the mesh router and also adopts a certificateless public key cryptography instead of a traditional public key infrastructure dut to the efficiency of public key management.

Sensor networks are expected to be used at anywhere in the near future and recently their security problems have been rising. Due to the limited computing power of senor nodes, it is impossible to use asymmetric cryptography approaches for the session key establishment or to apply advanced encryption method such as AES and DES for the data encryption. In this paper, therefore, we propose a key establishment and a data encryption scheme for secure and energy-efficient data transmission in wireless sensor networks (WSNs). The proposed schemes just treat simple operations as a message authentication code (MAC), exclusive-OR (XOR) and time-spacing key derivation function (TSDF). Additionally, the security of the proposed protocols is analyzed.
