However, the LWC is vulnerable to various constraints such as high-power consumption, time consumption, and hardware utilization and susceptible to the malicious attackers. In order to overcome this, a lightweight block cipher namely PRESENT architecture is proposed to provide the security against malicious attacks. The True Random Number Generator-Pseudo Random Number Generator (TRNG-PRNG) based key generation is proposed to generate the unpredictable keys, being highly difficult to predict by the hackers. Moreover, the hardware utilization of PRESENT architecture is optimized using the Dual port Read Only Memory (DROM). The proposed PRESENT-TRNG-PRNG architecture supports the 64-bit input with 80-bit of key value. The performance of the PRESENT-TRNG-PRNG architecture is evaluated by means of number of slice registers, flip flops, number of slices Look Up Table (LUT), number of logical elements, slices, bonded input/output block (IOB), frequency, power and delay. The input retrieval performances analyzed in this PRESENT-TRNG-PRNG architecture are Peak Signal to Noise Ratio (PSNR), Structural Similarity Index (SSIM) and Mean-Square Error (MSE). The PRESENT-TRNG-PRNG architecture is compared with three different existing PRESENT architectures such as PRESENT On-The-Fly (PERSENT-OTF), PRESENT Self-Test Structure (PRESENT-STS) and PRESENT-Round Keys (PRESENT-RK). The operating frequency of the PRESENT-TRNG-PRNG is 612.208 MHz for Virtex 5, which is high as compared to the PRESENT-RK.
