Decrypt Files Hello, I'm looking for someone who can write a file decryption script. Background: One of our workstations was phished. And as a result a bunch of files have been encrypted by some ransomware. Is there anyway you can remove the encryption? Its quite a few files so i would think its better if i send you a few files and if you are successfull you can write a script that can unlock ... 4 Computer Security, Cryptography Feb 13, 2016 Today6d 2h $230
Mathemaical model from MATLAB codes, Watermarking I already build a MATLAB software but I need to edit it and add more features to it. The second step is to drive a mathematical model to describe the whole procedure. Mathematical model is a way to describe an algorithm in terms of mathematical equations instead of codes. My software is about stereo video watermarking, that means you need good knowledge in both mathematical frequency transform... 12 Data Processing, Engineering, Matlab & Mathematica, Cryptography, Mathematics Feb 11, 2016 Feb 11, 20164d 14h $38
Applied mathmatics I was wondering if someone would be able to help me with some information theory problems. especially min-entropy and shannon entropy. I'm working on a scheme and I need help with understanding the entropy and how to improve the equations in order to perform robust theoretical security analysis. 18 Engineering, Algorithm, Statistics, Cryptography, Mathematics Feb 10, 2016 Feb 10, 20162d 16h $207
Expert in digital signatures and electronic signatures, cryptography I am looking to build a SaaS platform which offers electronic and/or digital signatures for businesses. I would like someone to provide me with advice and guidance on the scope of this project in terms of the technical requirements to satisfy US and EU law in order for the signature to follow an audit trail of the signature. I also need help understanding competitor’s patents which exist... 3 Patents, Cryptography Feb 9, 2016 Feb 9, 20162d 2h $487
