Now a day all the communications are carried out in wireless medium. It is necessary to transmit the confidential data in wireless media in secure manner. Cryptography is technique to protect electronic data in communication network. Hardware implementation of cryptography processor in field programmable gate array (FPGA) is major issues in terms of area, power and throughput. In this paper, we propose a hybrid crypto processor (HCP) for wireless network using flexible encryption and signature techniques. The main aim of proposed HCP technique used to provides secure wireless communication with aware of malicious attacks in the network, know to my knowledge, the proposed HCP hardware design is open the platform in signcryption. Generally, hybrid cryptography consists of data encapsulation mechanism (DEM) and key encapsulation mechanism (KEM). In HCP design, the efficient multiplier based ECC processor is proposed for data encapsulation over Galois field (GF (2 m )). Moreover, the improved enhanced Kurosawa and Desmedt hashing (EKD) hashing scheme is proposed for key encapsulation. The proposed HCP design is implementing in Xilinx tool with different field programmable gate array (FPGA) families. The result shows that effectiveness of proposed HCP design in terms of hardware utilization, power consumption and throughput over existing design.
