This paper designs an encryption and decryption system based on the FPGA. The system uses AES algorithm to encrypt and decrypt data. A pipeline IP core is designed with the reconfigurable technology complying with the Avalon bus interface specification. The IP core is applied to be a custom component on Nios II architecture so that the encryption and decryption processes through hardware can be controlled by software. Finally, the program is downloaded to the Altera DE2 development board and completes the testing of encryption and decryption processes. The system can be widely implemented in the field of data security.

Block ciphers play an essential role in securing the wireless communications. In this paper, an FPGA implementation of the new block cipher SMS4 is presented. The SMS4 Intellectual Property (IP) core includes a non-pipelined encryption/decryption data path with an on-the-fly key scheduler and supports both the Electronic Code Book (ECB) and Cipher Block Chaining (CBC) operation modes. Our result shows that the SMS4 IP core can achieve a high throughput using only a relatively small area. It is well suitable for the field of area restrained condition.

Nowadays there is a lot of importance given to data security on the internet. The DES is one of the most preferred block cipher encryption/decryption procedures used at present. This paper presents a high throughput reconfigurable hardware implementation of DES Encryption algorithm. This achieved by using a new proposed implementation of the DES algorithm using pipelined concept.  The implementation of the proposed design is presented by using Spartan-3E (XC3S500E) family FPGAs and is one of the fastest hardware implementations with much greater security. At a clock frequency of 167.448MHz for encryption and 167.870MHz for decryption, it can encrypt or decrypt data blocks at a rate of 10688Mbps.

This paper presents an architecture for 32-bit datapath Advanced Encryption Standard(AES) IP core based on FPGA. It uses finite state machine, and supports encryption, decryption and key expansion. The round-key is calculated before the beginning of encryption and decryption. It consumes less hardware resources. It is implemented on Cyclone II FPGA EP2C35F672C6, which consumes less than 55% logic elements of the resources. The IP core can operate at a maximum clock frequency of 100 MHz. Compared with 128-bit datapath AES, it can interface with CPU easily.


Data transmission with protection is main concept which is getting demand now a days for which number of encryption of data techniques are developed and now in this paper Advanced Encryption Standard (AES) Algorithm is used and is implemented on FPGA kit using vertex-3 family. We use 128 bits consists of input, key data, output data for this design. It is called an iterative looping with replacement box, key, loop in this design for both encryption and decryption of data. We use Xilinx software platform for simulation of our design that is AES by which area utilization and throughput is increased for achieving low power consumption, high data security, reduced latency and easy architectural design. This data operation is applicable in many areas.
