Cryptography techniques are considered secure and efficient algorithms. Despite that like other symmetric encryption algorithms, the secret key distribution is still considered as a critical issue. Again to encrypt or decrypt a single block (128-bit) of data, an essential amount of computational processing has to be done which consumes more power. Internet of things (IoT) is the extension of the Internet to connect just about everything on the planet. This paper presents implementation of data security algorithm based on Nano-AES or lightweight cryptography with 256 bit key for IOT application. A new one-dimensional substitution Box (S-box) is proposed instead of conventional 2-D S-box and previous 1-D S-box. Simulated result shows that proposed Nano-AES lightweight cryptography gives better performance than previous in term of delay, throughput, transmission time, efficiency rate.
