project name: Paillier System Dev enviroment:cpp in Linux description: This project is divided into few parts. 1th:implement the paillier encryption and Related operations 2th:implement a simple application in paillierSystem/simpleApplication/paillierEncServerAndClient/.which implemented the client pass the username and the data need enc then server enc and pass to client. in addtion: I have writen a python client to comunicate with the enc server. the code is in paillierEncServerAndClient/pythonClient/ requirments: 1th part: all works are based on gmp lib,you can used it when you insall this lib. remmeber to insall a gmp lib surport the c++. use configure command as following :./configure --enable-cxx 2th part: you need to modify the iP then you can use this code in you linux machine.if all are ready then you can run the makefile then you will get server and client in paillierSystem/simpleApplication/paillierEncServerAndClient/bin 3th part: you need a pub_key.txt.//the location you can see in the server.cpp license: Every can use it without my permission.I won't be responsible to any errors. this work based on gmp lib and my paillier code refered to(of course i rewrite all the code,and my code is in cpp based on gmpxx instead of gmp) more important i have do some improve. libpaillier on http://hms.isi.jhu.edu/acsc/libpaillier/#description.this lib has used the /dev/urandom and /dev/random ,I herit it from the lib too, so the code can only run on linux or similiar system. of course i rewrite all the code,and my code is in cpp based on gmpxx instead of gmp) more important i have do some improve. 1、i modify some errors in original code(generate the r). 2、i used a randomness g not n-1 as in original code. 3、I have implemented some c++ interfaces I don't know if need you to contact them. PS:I will implemented the features in codeblocks ide first.I will add the makefile and releases when i have more free time.
