$30-250 SGD

Paid on delivery
Write (Java or C/C++) UDP programs to allow two parties to establish a secure communication channel. For simplicity, let us call the programs “Host” and “Client”, which are executed by Alice and Bob, respectively. Alice and Bob share a common password PW, which contains 8 alphanumeric characters. Alice also has a public and privacy key pair (pk = gb mod p, sk = b) for the Diffie-Hellman key exchange. They want to establish a secure communication channel that can provide data confidentiality and integrity. This will be done via the following steps: (1) perform a client authentication and key exchange protocol; and (2) use the shared session key derived from step (1) to secure the real communication

I am very proficient in c and c++. I have 16 years c++ developing experience now, and have worked for more than 7 years. My work is online game developing, and mainly focus on server side, using c++ under Linux environment. I made many great projects using c++, for example, I made the tools which could convert java codes into c++ scripts, of course garbage collection included, this was very similar to a compiler, and was very complex. I also made our own mobile game using c++, I can show you the demo of client, if you like. I am very proficient in java also. I have a very good review on Freelancer.com, I never miss a project once I accept the job, you can check my review. Trust me, please let expert help you.
