Abstract: Security is the most important factor in Internet of Things (IoT). The public key cryptography systems like RSA, DSA are not suitable for IoT Devices because of the key size and energy consumption. ECC cryptography system is more suitable for IoT lightweight devices. ECC provides same level of security as like RSA with small key size and less energy computation. Key exchange is challengeable task due to Routing transmission attacks like DoS attack. The proposed technique is to enhance key exchange system in ECC based security protocols. The public key is encrypted before shared into network. The path selection algorithm is used to choose two different paths. One is for encrypted public key sharing and another is for unlock-key for encrypted public key sharing. The possibility of attacks during key sharing is investigated; the key size and energy consumption is compared. This technique is suitable for Tmote Sky and MICAz nodes
