SgxCryptoFile

Introduction

SgxCryptoFile is an application for encrypting and decrypting HLS chunks using Intel SGX.

The encryption and decryption are implemented based on T_CRYPTO library provided by Intel SGX SDK.

It uses AES-128-GCM algorithm and it was written in pure C language.

In addition, it generates an encryption/decryption benchmark time.

Actually, the key is hardcoded inside the enclave.

Build the SgxCryptoFile

Prerequisites:

• Ensure that you have the following required operating systems: Ubuntu* Desktop-14.04-LTS 64bits

• Install Intel(R) SGX SDK for Linux* OS and follow all the instructions;

• Use the following command to install the required tools to build SgxCryptoFile application:

  $ sudo apt-get install nasm

Build the SgxCryptoFile

The following steps describe how to build the SgxCryptoFile application.

• Build the project with the prepared Makefile:

• Hardware Mode, Debug build:

  $ make SGX_MODE=HW SGX_DEBUG=1

• Hardware Mode, Pre-release build:

  $ make SGX_MODE=HW SGX_PRERELEASE=1

• Hardware Mode, Release build:

  $ make SGX_MODE=HW

• Simulation Mode, Debug build:

  $ make SGX_DEBUG=1

• Simulation Mode, Pre-release build:

   $ make SGX_PRERELEASE=1

• Simulation Mode, Release build:

   $ make

• To clean the files generated by previous make command, enter the following command:

  $ make clean

Run the SgxCryptoFile

Encrypt File

To encrypt a file, enter the following command:

$ ./sgxCryptoFile -e -i [INPUT_FILE] -o [OUTPUT_FILE]

Decrypt File

To decrypt a file, enter the following command:

$ ./sgxCryptoFile -d -i [INPUT_FILE] -o [OUTPUT_FILE]
