1. Simon works in a government office where encrypted messages are regularly received. He knows that an affine cipher is the standard method of encryption used by the office, and has access to the machine which day, when there is not much work to do, Simon decides to work out the affine function used in the machine. He inputs 1 and the machine outputs 5. He inputs 2 and the machine outputs 19. Show how he uses this to obtain the function.nnn2. Patrick and Jacquie both use the same Hill cipher based on the matrixnM = |2 13|n |23 1|n to send each other encrypted messages.n(a) Without using Maple, show how Patrick uses M to encrypt the message:n` The room for the PASS session has changed.'n(b) In order to decrypt Patrick’s message, Jacquie must invert M. What matrix doesnshe...

This project requires a knowledge of cryptography. We will need a candidate who has written a solution for an open knight's tour in the past. Our scope here is of GF 2^infinity. Which allows us the ability to program an open knight's tour solution involving 16 by 16 squares of elements. We need an algorithm in either straight forward approach or divide and conquer method or neural network. We need a method that will generate solutions in decimal numbers lined up according to the knight's move. This will follow a standard state as specified. Before you are awarded this bid :All contestant will need to write a simple program what will solve an 8 by 8 square OPEN knight's tour solution. When the scope increase things get a little complicated. To keep is simple...

I have done around 60% of the project. Need some verification and some coding.

It is based on Cryptography. I have done most of the parts. Just some guidance and verification is required with some more coding.

I need to implement the code on Arduino Mega 2560. I have already implemented the basic functions in C on Mega. Now as per given algorithm the functions need to arranged methodically and accordingly called to get the output. Since the lower level functions are all done so it won't be too time consuming to get the main code working for someone proficient in Arduino and c coding.

I need a Java web services expert who is able to develop web services and web service clients using JAX-WS API. You should be familiar with handling MTOM attachments, dynamic web services (both on client using Dispatch and on server) and...you will receive the payment on successful subtask completion. The current subtask intended to implement digital signature creation and verification. All types of signatures should be handled: header-places, in-message signature for app data and attachments, detached signatures for app data and attachments. GOST algorithms should be used for digital signatures. This means that specific Java cryptography provider should be used. Please add "WS" as the first word of you message. Please let me know what is your experience developing w...

Each article is to be fairly short (something like 500 to 1500 words) and are intended to act as introductions or overviews to a category in which more detailed, more technical articles will be written by other members of my team. All articles will be in the fields of Information, Network and Cyber Security. They will cover topics such as Application Security, Cryptography, Forensics, Malicious Software, Network Security and Physical Security. Many of the articles will be more like extended definitions and it is intended that all articles feature as little technical terminology as possible. More like a lay-man's guide to a topic. They will be similar to Wikipedia articles, in their purpose and scope although often much shorter, much more...

I'm looking initially for 10 images to be created, as banners to go on top of a web site. The banners must be 650px by 150px and must be able to be cut down to 300px by 150px for "thumbnails". All images should be in the same style and there should be one image per category. The categories are all Computer Security related and are things like: Cryptography, Forensics, Network Security and Malicious Software. The artist is given freedom to create any image within the category theme for each category although if more specific information for each one is need that can be supplied too.

I am proposing an encryption system which has the potential to make things a little faster and could possible stir cryptography to claim openness as well. I call it eXCIPHER: It is described by way of mathematical elements of the GF. This is necessary for grasping the specifics. This is followed by the Knight's tour analogy: The key rationale (external context), embedded in the design proposed. The description of the cryptographic system will be clearly shown to volunteers or prospects. Other interested people (students) are welcomed to it. The implementation and practicality of the cipher (eXCIPHER) is been patterned as a prototype in java at the time of writing. My goal will be to make this cryptographic system available for collective development. The promise of nu...

...apparent, but with a human touch. Some visual styles to draw from would be Bladerunner, Ghost in the Shell, Tron-Legacy, and the 2012-13 Star Trek movies. Basically, NSA meets Bladerunner. Some background information on what we would like to showcase would be something along the lines of technologies that we make use of, such as machine learning, GPU processing, massively parallel programming, and cryptography. A lot of the work we do is funded by the Department of Defense so keep that in mind. I should add data science research, data visualization, historical and graphical information, computational biology, and complexity sciences to that list as well. What we have in mind is something that is competent and has the coolness to bleed through but with a subtle sense of human touc...

...we will not assist them further than our legal obligations and therefore protecting user data from any party is the only way to achieve total privacy. No data will be stored on any individual except the e-mail addresses on the server of course and the password in an encrypted form of some type so we will not know what it is the user chooses. I believe a way of doing this is called public-key cryptography. 2. The service should only be accessible as a Tor hidden service. I understand this is not difficult to set up so if you do not know what this is, it is not a problem as it is just a way for users to access their e-mail anonymously. 3. The service must offer 3 plans. A free plan, and two paid plans, the only difference is the additional mailbox size and also personal stora...

We have a partially completed Delphi project that requires one last step to finish it off. The project is for decrypting sectors from a TrueCrypt volume. This is NOT a password cracking a program. The password is known to the user at the time of running the program. We only require a routine to decrypt any sec...skills. TrueCrypt is open source and written in C/C++. Therefore knowledge of C/C++ is required in order to understand how to perform the sector decryption. You will be supplied with the full test application written in Delphi that requires completion. No GUI skills are required, as you will only be completing the test application. Please no time wasters. If you do not know anything about Cryptography - DO NOT BID. If you do not know how to program in Delphi - D...

We are looking for a developer with experience in cryptography and "byte-level" java development with a focus on performance. The project is to develop a library that can encrypt and decrypt byte arrays using a supplied standard called CCM*. This is a variation on AES-CCM block cipher mode. The CCM* mode coincides with the original CCM mode specification for messages that require authentication and, possibly, encryption, but does also offer support for messages that require only encryption. As with the CCM mode, the CCM* mode requires only one key. There is an extensive specification which also includes test vectors that should serve as input for unit tests. Writing the unit tests to validate that it works is also part of the project. Also, there is a C implementat...
