This project presents complexity analysis and hardware implementation of extensible modulo addition [15] encryption algorithm on a 32-bit lightweight FPGA based block cipher called INFLEX, which is designed for the internet of things (IoT) environment, supporting 64-bits key. It is designed for constrained hardware resources yet providing a highly secure scalable configuration for the variety of applications. This characteristic is obtained by the use of generalized Feistel structure combined with an improved block inflation feature. INFLEX follows a typical ARX (Add, Rotate, XOR) round function with a distinguished feature of block expansion and collapse as per user selected control string, which makes INFLEX act as a tweakable Cipher. We have shown comparison of INFLEX algorithm robustness and immunity against linear and differential attacks and demonstrated that it outperforms one of the benchmark block Ciphers Speck32/64 proposed by national security agency (NSA).

Among the block cipher algorithms, AES or DES is an excellent and preferred choice for most block cipher applications. But AES and DES are not very suitable for hardware implementation because of the high cost that they require large areas of routing and the processing efficiency is low, relatively. So lightweight cipher algorithms come into beings, among which PRESENT is very competitive. Along with the structure of a message authentication algorithm ALRED, a new family of Tunable Lightweight MAC based on PRESENT is proposed, that is TuLP. However, PRESENT is not able to resist side channel attack, so is TuLP, of course. For the above reason, in this paper, we provide an improvement of PRESENT by inserting random dummy cycles as well as shuffling to strengthen the security of PRESENT against side channel attacks. We will implement PRESENT and TuLP in Verilog and do simulation on Xilinx ISim platform. At last, we would like to provide the power analyzing of Xilinx XPower.

We present Orthros, a 128-bit block pseudorandom function. It is designed with primary focus on latency of fully unrolled circuits. For this purpose, we adopt a parallel structure comprising two keyed permutations. The round function of each permutation is similar to Midori, a low-energy block cipher, however we thoroughly revise it to reduce latency, and introduce different rounds to significantly improve cryptographic strength in a small number of rounds. We provide a comprehensive, dedicated security analysis. For hardware implementation, Orthros achieves the lowest latency among the state-of-the-art low-latency primitives. For example, using the STM 90nm library, Orthros achieves a minimum latency of around 2.4 ns, while other constructions like PRINCE, Midori-128 and QARMA9-128- σ0 achieve 2.56 ns, 4.10 ns, 4.38 ns respectively.
