| Abstract | Of late, the massive use of pervasive devices in the electronics field has raised the concerns about security. In embedded applications or IoT domain implementing a full-fledged cryptographic environment using conventional encryption algorithms would not be practical because of the constraints like power dissipation, area and speed. To overcome such barriers the focus is on lightweight cryptography. In this paper a new lightweight PRESENT cipher has been proposed which has modified the original PRESENT cipher by reducing encryption round, modifying the Key Register updating technique and adding a new layer in between S-box layer and P-layer of the existing encryption-decryption process. The key register is updated by encrypting its value by adding delta value function of TEA (Tiny encryption algorithm), which is another lightweight cipher. The addition of extra layer helps us to reduce the PRESENT round from 31 to 25 which is the minimum round required for security. The efficiency of the proposed algorithm is increased by encrypting the key register. The proposed algorithm proves its superiority by analyzing different software parameter analysis like N-gram, Non-Homogeneity, Frequency Distribution graph and Histogram. |
