We will have to add userIDs, email address, IP addresses to a black list, and code the web site to block them from connecting to the server for a period of time. You'd have to be willing to become somewhat knowledgeable about how Bitcoins and cryptography work to do this project... but you will not need to be an expert on BitCoins or cryptography by any stretch of the imagination. You must speaks excellent English and you should be a citizen of the USA, or live in a country where you could be extradited if I catch you putting backdoors in this system... or if the Feds or my book keepers come knocking on my door, asking about shady transfers, embezzlement, etc. ...

    Hi, I need help to make an application of cryptography. I had trouble in some parts. nearly 70 percent of this application is almost done, so if you are interested I hope you can do something like the following. 1. Secret-key cryptography divided into block and stream ciphers. As opposed to block ci-phers, stream ciphers encrypt each data symbol (as small as a bit) into a ciphertext symbol under a time-varying transformation. 2. LFSR controlled by another LFSR (which may be the same one). 3. Cellular Automata (CA) will be used for solutions of linear diference equations with constant coecients. If you understand and experts, we can talk about things that I need on a private message. Thank you Sincerely. Flynn

    In an olden research on sensor network security mainly considers homogeneous sensor networks, where all sensor nodes have the same capabilities. Research has shown that homogeneous ad hoc networks have poor performance and scalability. Most existing key management schemes try to establish shared keys for all pairs of neighbor sensors, no matter whether these nodes communicate with each other or not, and this causes large overhead. We propose a novel routing-driven key management scheme, which only establishes shared keys for neighbor sensors that communicate with each other.

You are provided with a simple but working C# streaming video server and video player client. The client and server in this system are communicating using the Real-Time Streaming Protocol (RTSP) and send data using the Real-time Transfer Protocol (RTP). This system as provided is totally insecure; all the streaming data are transmitted in the clear. You will be required to provide confidentiality, message authentication, and replay protection to the RTP traffic, using both the cryptography and security features found in the .NET platform and Mono library. The required security features are: 1...

The objective is to create a private CA that issues certificates that are tied to a specific computer. There are several methods to uniquely identify a Windows computer based on hardware IDs (MAC addresses are not secure enough). Next, a C# program will connect to the server using TCP and use an SslStream to establish a secure connection. The RemoteCertificateValidationCallback callback from SslStream will then validate that the certificate of the server is signed by the private CA. I would also like a demonstration of mutual authentication. The C# program must detect if the machine certificate has been moved to another computer and reject it. The deliverables will be shell scrip...
