...using multiple simultaneous connections to the same game server in order to increase their odds to win. 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. ...

Moreover, the intruders can even manipulate it as per their requirement or reveal it in front of others. Further in certain in cases it can also be used for launching an attack. Stenography is the only solution to it. This is a most common technique of hiding information in the form of digital images. In comparison to the cryptography technique this method not only make it known to others that information is retained in the hidden form but also restrict other from even making out that any such information exists. As more and more people are going the cyberspace revolution this technique of steganography is also gaining a lot of importance. This is the way of hiding information in such a manner that it does not enable the intruder to detect the secret message. An array of communic...

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.

Encryption of a Video streaming application 1. Goals This assignment is to apply security to an application; in particular cryptography to secure the data that this application uses. 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...

I need an outstanding logo designed for my game website. . I will be using this logo on all my webpages. I will also be delivering to animator to build a video intro. Theme is cryptography / code-breaking. My business creates video playlists that use coded messages to guide players to the hidden video at the end of the game. Prize money is awarded. I'm not the creative type, and thought someone who went to the site and actually played the game would be inspired to create a knockout logo for it.

I need a music player with only the basic functions ( Play / Pause / Skip / Volume ) and that are enabled and disabled by admin password. The music is downloaded from a FTP Server and stored in a cache folder. The cache folder must have cryptography or hidden so that the user can't "steal" the music ( similar to spotify / deezer / grooveshark) . When the user clicks play for the first time, the player opens a "downloading screen" and only starts playing after 1gb of music downloaded in the cache (The purpose of the local storage is that the music never stops playing, even if there is no internet available). The cache folder have a maximum size of 5GB and keeps downloading music in the background while playing the local music. * we also need an website ad...

I need an expert in SSL who is comfortable with openssl and the C# cryptography standard libraries. 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...
