    Hi, I wanted to implement research work on the AES(Advnaced Encryption Standard) algorithm and differential scan attack on the same to retriever secret key. In addition, the prevention mechanism against such attack has to be developed. Coding and simulation in verilog(Xilinix-ISE/Modelsim) will be fine. Also, requires documents for the implementation (step-by-step procedure), block diagram for each method, and the work flow diagram. Result analysis and transcript for research paper at the end would be appreciated. Kindly go through the research paper attached for your reference. Also, find the proposed implementation plan attached. It's a research work so I don't want it to be disclosed and well managed,explained in a proper way. Will you be able to implement all this? I am ready for the offer you ask for. Thanks.

    We need to be able to match the attached java encryption algorithm in C#. The attached java files have AES 256 algorithm with some modifications. We need a C# algorithm with the same logic in the java files. To confirm that you have accomplished the task, you'll need to send us a corresponding C# code that you have written and subsequently provide a guide on how to generate sample cipher texts using the code. We shall then decrypt the cipher texts using the java files. POINTS TO NOTE: [url removed, login to view] 256 AES with some modifications. The magic is in the modification of the encryption.. [url removed, login to view] the server side we used a function that took into account the time of creation and some random things we inserted on the servers side. so it could only be replicated on that machine... private static byte[] getRawKey(byte[] seed) throws Exception { KeyGenerator kgen = [url removed, login to view]("AES"); SecureRandom sr = [url removed, login to view]("SHA1PRNG","Crypto"); [url removed, login to view](seed); [url removed, login to view](128, sr); // 192 and 256 bits may not be available SecretKey skey = [url removed, login to view](); byte[] raw = [url removed, login to view](); return raw; } 3. mostly there... its gets a key for the encryption using Secure Random instance
