A Novel Hybrid Encryption Scheme using RSA-Co-CP-ABE for Ciphertext Transmission in Cloud Environment

Operating environment:

Installation

This section describes the installation of the OpenABE source code (libopenabe-1.0.0-src.tar.gz) on various platforms. The OpenABE currently supports several operating systems including multiple versions/distros of Linux, Mac OS X and Windows.

Debian/Ubuntu-based Linux

To compile OpenABE on Ubuntu or Debian Linux-based distro, first run the deps/install_pkgs.sh script from the source directory to install the OpenABE system-specific dependencies as follows:

cd libopenabe-1.0.0/
sudo -E ./deps/install_pkgs.sh

Note that you only have to do this once per system setup. After completion, you can proceed to compile the OpenABE as follows:

. ./env
make
make test

All the unit tests should pass at this point and you can proceed to install the OpenABE in a standard location (/usr/local) as follows:

sudo -E make install

To change the installation path prefix, modify the INSTALL_PREFIX variable in libopenabe-1.0.0/Makefile.

Quick Start

To compile example C++ apps that use the high-level OpenABE crypto box API, do the following:

. ./env
make examples
cd examples/

Then, our contribution can then be verified as follows:

First, start the server and listen to the client, waiting for the client to send the RSA public key:

Server:
./my_server

Next, open the client and send the RSA public key encrypted with CP-ABE to the server(At this point you need to reopen a terminal.):

Client:
./my_client 8191

The server receives the key sent by the client and sends confidential information:

Server:
client ip: 127.0.0.1     port: 44096
recive[708]: AAABrKETqm/Js74xM0Ovfc.....QpAgq8Q8wwDVGZRYhYuWCbQ==
The result after CP-ABE decryption is :
8191
e:8191
d:31
Please enter the message to be sent to Client:

# HelloWorld is the message sent.
HelloWorld

Real message sent：eh^h,]
write finished. len: 10

The client receives the information:

Client:
real message：
HelloWorld
client finished.
