Implementation of Software IPsec Communication using ARIA Cipher Algorithm in SDN

In this paper, we implement IPsec communication system that processes encryption/decryption using ARIA cipher algorithms in term of software to confirm the possibility of hardware-based implementation of ARIA cipher algorithms. For encryption/decryption processing using ARIA cipher algorithm, we implement ARIA cipher algorithm in kernel and verify the function of encryption/decryption using IPsec application. we use strongSwan application for IKE operation of IPsec process. To analyze a performance, we test a transmit performance between end nodes using IPsec and ARIA cipher algorithm and confirm the hardware implementation possibility.
