An Efficient VLSI Design of AES Cryptography Based on DNA TRNG Design
This document describes an efficient VLSI design for AES cryptography using a true random number generator (TRNG) and DNA encoding. It aims to improve security and reduce area and delay compared to standard AES. The design generates random round keys using a TRNG instead of the standard key expansion process. It further encodes a partial key from the TRNG using DNA encoding to produce the full 128-bit key, strengthening security. Simulation and synthesis results show the TRNG-based AES has lower area and delay than standard AES. Combining the TRNG with DNA encoding further optimizes the design.
What is AES? Advanced Encryption Standards
AES (Advanced Encryption Standard) is a symmetric block cipher encryption method that uses a block size of 128 bits and key sizes of 128, 192, or 256 bits. It is an iterative cipher based on substitutions and permutations that performs all computations on bytes rather than bits. The encryption process consists of initial round, main rounds, and final round, with the number of main rounds varying based on key size. Decryption undoes the encryption process in reverse order using inverse operations. AES-256 is considered the most secure variant due to its 256-bit key size.
High throughput FPGA Implementation of Advanced Encryption Standard Algorithm
The growth of computer systems and electronic communications and transactions has meant that the need for effective security and reliability of data communication, processing and storage is more important than ever. In this context, cryptography is a high priority research area in engineering. The Advanced Encryption Standard (AES) is a symmetric-key criptographic algorithm for protecting sensitive information and is one of the most widely secure and used algorithm today. High-throughput, low power and compactness have always been topic of interest for implementing this type of algorithm. In this paper, we are interested on the development of high throughput architecture and implementation of AES algorithm, using the least amount of hardware possible. We have adopted a pipeline approach in order to reduce the critical path and achieve competitive performances in terms of throughput and efficiency. This approach is effectively tested on the AES S-Box substitution. The latter is a complex transformation and the key point to improve architecture performances. Considering the high delay and hardware required for this transformation, we proposed 7-stage pipelined S-box by using composite field in order to deal with the critical path and the occupied area resources. In addition, efficient AES key expansion architecture suitable for our proposed pipelined AES is presented. The implementation had been successfully done on Virtex-5 XC5VLX85 and Virtex-6 XC6VLX75T Field Programmable Gate Array (FPGA) devices using Xilinx ISE v14.7. Our AES design achieved a data encryption rate of 108.69 Gbps and used only 6361 slices ressource. Compared to the best previous work, this implementation improves data throughput by 5.6% and reduces the used slices to 77.69%.

Enhanced Advanced Encryption Standard (E-AES): using ESET
This document proposes an enhanced version of the Advanced Encryption Standard (AES) called E-AES. E-AES increases the key size to 2048 bits and the block size to 1024 bits. This provides more security than AES, which uses a 128, 192, or 256 bit key on a 128 bit block. E-AES specifies 64 rounds of encryption, compared to AES which uses 10 to 14 rounds depending on key size. The encryption process of E-AES involves four transformations at each round: byte substitution using an S-box, shifting rows of the state matrix, mixing data within columns, and adding a round key. This enhanced algorithm is proposed to address known attacks on AES and the use of its 16 year old standard with

There is great research in the field of data security these days. Storing information digitally in the cloud and transferring it over the internet proposes risks of disclosure and unauthorized access, thus users, organizations and businesses are adapting new technology and methods to protect their data from breaches. In this paper, we introduce a method to provide higher security for data transferred over the internet, or information based in the cloud. The introduced method for the most part depends on the Advanced Encryption Standard (AES) algorithm. Which is currently the standard for secret key encryption. A standardized version of the algorithm was used by The Federal Information Processing Standard 197 called Rijndael for the Advanced Encryption Standard. The AES algorithm processes data through a combination of Exclusive-OR operations (XOR), octet substitution with an S-box, row and column rotations, and a MixColumn operations. The fact that the algorithm could be easily implemented and run on a regular computer in a reasonable amount of time made it highly favorable and successful.
In this paper, the proposed method provides a new dimension of security to the AES algorithm by securing the key itself such that even when the key is disclosed, the text cannot be deciphered. This is done by enciphering the key using Output Feedback Block Mode Operation. This introduces a new level of security to the key in a way in which deciphering the data requires prior knowledge of the key and the algorithm used to encipher the key for the purpose of deciphering the transferred text.

Novel Adaptive Hold Logic Circuit for the Multiplier using Add Round Key and ...
Digital multipliers are among the most critical arithmetic functional units in many applications, such as the Fourier transform, discrete cosine transforms, and digital filtering. The through put of these applications depends on multipliers, if the multipliers are too slow, the performance of entire circuits will be reduced. The negative bias temperature instability effect occurs when a PMOS transistor is under negative bias (Vgs = −Vdd), increasing the threshold voltage of a PMOS transistor and reducing the multiplier speed. Similarly, positive bias temperature instability occurs when an NMOS transistor is under positive bias. Both effects degrade the speed of the transistor and in the long term, the system may be fail due to timing violations. Therefore, it is required to design reliable high-performance multipliers. In this paper, we implement an aging aware multiplier design with a novel adaptive hold logic (AHL) circuit. The multiplier is able to provide the higher throughput through the variable latency and can adjust the adaptive hold logic (AHL) circuit to lessen performance degradation that is due to the aging effect. The proposed design can be applied to the column bypass multiplier.

The fact that the algorithm could be easily implemented and run on a regular computer in a reasonable amount of time made it highly favorable and successful.
In this paper, the proposed method provides a new dimension of security to the AES algorithm by securing the key itself such that even when the key is disclosed, the text cannot be deciphered. This is done by enciphering the key using Output Feedback Block Mode Operation. This introduces a new level of security to the key in a way in which deciphering the data requires prior knowledge of the key and the algorithm used to encipher the key for the purpose of deciphering the transferred text.

An Efficient VLSI Architecture for AES and It's FPGA Implementation
This document discusses the design and FPGA implementation of an efficient VLSI architecture for the AES encryption algorithm. It begins with an introduction to cryptography and the AES algorithm. It then describes the key components of AES including the state array, substitution bytes, shift rows, mix columns, add round key transformations, and key expansion. The document proposes a pipelined design to reduce encryption delay by generating round keys in parallel with encryption rounds. Simulation results show this pipelined AES architecture can operate at higher clock frequencies, increasing encryption throughput for time-critical applications. In conclusion, the hardware implementation provides faster encryption speeds and higher throughput compared to a software solution.
Novel Adaptive Hold Logic Circuit for the Multiplier using Add Round Key and ...
Digital multipliers are among the most critical arithmetic functional units in many applications, such as the Fourier transform, discrete cosine transforms, and digital filtering. The through put of these applications depends on multipliers, if the multipliers are too slow, the performance of entire circuits will be reduced. The negative bias temperature instability effect occurs when a PMOS transistor is under negative bias (Vgs = −Vdd), increasing the threshold voltage of a PMOS transistor and reducing the multiplier speed. Similarly, positive bias temperature instability occurs when an NMOS transistor is under positive bias. Both effects degrade the speed of the transistor and in the long term, the system may be fail due to timing violations. Therefore, it is required to design reliable high-performance multipliers. In this paper, we implement an aging aware multiplier design with a novel adaptive hold logic (AHL) circuit. The multiplier is able to provide the higher throughput through the variable latency and can adjust the adaptive hold logic (AHL) circuit to lessen performance degradation that is due to the aging effect. The proposed design can be applied to the column bypass multiplier.
EFFICIENT VLSI IMPLEMENTATION OF THE BLOCK CIPHER RIJNDAEL ALGORITHM
This document summarizes a VLSI implementation of the Rijndael block cipher algorithm. It describes the architecture of the Rijndael chip, which was selected as the new private-key encryption standard called AES. The chip uses parallel processing and optimizations like memory sharing and pipelining to achieve a throughput of 2.18Gbps. Simulation results are provided to validate the encryption and decryption operations. Further development opportunities are discussed to improve speed and reduce power consumption to make the cipher suitable for embedded applications.
IMPLEMENTATION OF AES AS A CUSTOM HARDWARE USING NIOS II PROCESSOR
This document describes the implementation of the Advanced Encryption Standard (AES) algorithm as a custom hardware accelerator connected to a Nios II processor system. AES was written in VHDL and connected to the Nios II system through GPIO pins. This allows AES operations to be controlled through C code in the Nios II IDE while running the AES algorithm in hardware, improving encryption speeds significantly compared to an all-software implementation. Synthesis results showed the hardware AES implementation reduced the number of clock cycles needed for encryption by over 99% compared to running AES solely in software on the Nios II processor.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
