LiNA: Lightweight algorithm for secure internet of things.

In the present paper a new idea has been proposed that involve a low-cost encryption/decryption algorithm called (LiNA cipher) that manipulate data with small devices of limited resources. LiNA works under the concept of symmetric block cipher with 64-bit size for data block and with ciphering key of 80-bit for the secret key. The proposal cipher looped with up to 12-rounds to increase data security and the complexity of decryption against the crypto-analysts. The LiNA structure is a product and iterated lightweight cipher with substitution and permutation network design. LiNA cipher implemented and designed by a series of logical and mathematical methods that reduced the gate equivalent (GE) efficiently to match the IoT embedded devices. The experimental results of LiNA cipher after the comparison to the other lightweight block ciphers shows an outstanding execution in the terms of performance and efficiency, especially, with low amount of (GE) that estimated by 1408 GE.
