Comparison of various strategies of implementation of the algorithm of encryption AES on FPGA

2006 IEEE International Symposium on Industrial Electronics, 2006

The data security is a significant subject for which various solutions algorithms were proposed. In 2001, Advanced Encryption System (AES) was accepted like a standard FIPS. AES is a symmetrical algorithm of encoding intended to replace DES which had already shown certain faults of safety in the data protection. Since then, of many achievements on hardware and software were proposed by combining various architectures. The throughput reached go from 20 Mbps to 70 Gbps according to technology and architecture used. This article presents an architecture which can be implemented on the FPGA Xilinx XC2V6000, by applying dynamic reconfiguration and reaching a speed of execution of 43 Gbps. This architecture employs only 2xxx CLB' S allowing a considerable economy of the resources.

Study of Different Fpga Systems Implemented Aes Algorithm: A Review

2020

Cryptography is technique of preserving data from unwanted objects by transforming in the pattern that is unrecognizable by hackers while transmission. Encryption is the process where maximum part of informtion is scrambled like text-data, images, audio, and video so to make the data undcipherable, unseen untillthe proces is donef. The primary objective of cryptography is to protect information from non authoritzed hackers. The data decryption decryption is nothing but the receving of encrypted data which recreates the original information. At present cryptography is not limited to secure military document but known as one important method for policy of security cosidering any organization and recognized as standard for industry for giving secure data, access control, and financial agreement through electronic medium. The primary information that will be send or saved is known as plaintext, the which either a person or machine can read. Whereas the hidden information called cipher t...
