Implementing an AES cryptographic algorithm

Hi, I need to implement a VHDL aes algorithm on a DE0-Nano boad. As I'm not a cryptographic expert I'd like to find an existing and easy-to-use implementation. I've found several on the internet but I don't know which one I should use. Can someone tell me what is important to look at or if they know a good implementation I could use? Thanks.

implimentation of ADPCM in Matlab

i am doing my Thesis on implementation of ADPCM and 256-bit voice Encryption . i studied the literature and basic working of the algorithm. now i want to implement it in matlab. is there any built in functions for aes and ADPCM in matlab or he have to compose the code by our self. the flow of work is Human voice

URGENT... NEED verilog code for aes algorithm

try opencores. There are plenty of done and tested aes implementations.

use of SRL16E register in AES algorithm

Is the use of SRL16E is only for shifting the data in aes algorithm...i am a lil bit confused...bcoz previously my aes code for decryption is puely combinatonal but now i make it clock based with ther help of different register...the problem is that when i am removing SRL16E from the code o/p is not coming...please help me ....

hardware implementation of AES 128 bit

i want to implement aes algorithm with 128 bit i/p and 128 bit key on virtex 5 fpga board. can anyone suggest me how to implement it.. i've written the code. bt find it difficult during hardware implementation.. as the i/p and key size is too large.. plzz help mee if u have some idea.. :-?:-(

AES modes of operation benefit as i think so

I think that the mode of operation benefit is : With a symmetric key block cipher algorithm, the same plaintext block will always encrypt to the same ciphertext block when the same symmetric key is used. If the multiple blocks in a typical message (data stream) are encrypted separately, an adversary could easily substitute individual block

AES mode of operation ???

Alsalam alikom how are u all? I hope u r fine. well i want to understand the aes mode of operation (CBC,FCB,....) as i only understood the aes encryption and decryption algorithm block diagram in FIPS-197 "aes NIST standard" and in the reference of cryptography of ""William Stalling" ch.5, but I can't figure how to (...)

Verilog code required for 128x32 bit Montgomery multiplier pls..

For aes alone, you dont need montgomery multiplication. for public key, you do need montgomery multiplication. You can understand the algorithm and code it yourself. I have a reference but its in VHDL Finite-Field Arithmetic Circuits Under chapter 3, see article 3.4.3

Help needed in Simulation of AES algorithm in Modelsim

Hi! i have implemented aes encryption and decryption algo on FPGA using verilog. I have simulated the result of encryption module, the problem that i am facing is in the simulation of Decryption module.How can i get the correct result?Also what if i want to send the input from matlab to FPGA board and get back the decrypted data from FPGA otno Mat

What is xxx.tgz.enc files? and use what command to open it?

Usually a .enc file is a encrypted one, using a DES or aes algorithm.

AES encryption algorithm written by verilog

I have trouble implementing aes encryption algorithm with verilog, does any one knows how to implement it, what's important is that the s_box is based GF(28),thank you very much

The difference between symmetric and asymmetric cryptographic algorithms

What is the story used by your lecture materials to help you remember the difference between symmetric and asymmetric cryptographic algorithms? 1. Symmetric: 2. Asymmetric: 3. TLS is the next generation of SSL 4.0. What cryptographic algorithm is used for TLS? a. El Gamal b. Diffie Hellman c. RSA d. aes

Multiple VHDL files and DES/AES Core

Hi Antony As I understand from you post the answers to your questions are below. You have downloaded the VHDl files for the Encryption algorithm .You will find that there will be a top level file that binds all the modules in the design. In VHDL we have top level ENTITY that has all the bus designed entities attached to it. All you need is

vhdl source code for AES algorithm

hi i have aes code. what purpose u r looking? send details to sorkam@gmail.com. bye

How Security algorithm??

There are many Cryptographic algorithms such as DES: Data Encryption Standard aes: Advanced Encryption Standard but first you need to know how the algorithm work.then you can write the code. Try this book Cryptographic Hardware and Embedded Systems

What are the differences between AES and IDEA algorithm?

hi 2 all wht r the diff. b/w aes and IDEA alogorithm. whic s better on wht basis. thanks in advance

Looking for books about secured data communication

need a book on secured data communication plz tell me some link or can tell me about these algorithms or give some material . 1. Ciphering algorithm 2. aes algorithm 3. DES algorithm

What is AES algorithm?

Hi All, What is aes algorithm? Where this standard is used? What are the advantages and disadvantages? Thanking You Chin

how to design pata slaver?

You want to encrypt the data in the ATA hard disk using the aes algorithm? I've used the FPGA chip to realize that. But I can only realize the PIO mode, and the DMA mode is very hard to realize. How do you want to do that?
