---------------------------
|
||||
Purpose of LocalAttestation
|
||||
---------------------------
|
||||
The project demonstrates:
|
||||
- How to establish a protected channel
|
||||
- Secret message exchange using enclave to enclave function calls
|
||||
|
||||
------------------------------------
|
||||
How to Build/Execute the Sample Code
|
||||
------------------------------------
|
||||
1. Install Intel(R) Software Guard Extensions (Intel(R) SGX) SDK for Linux* OS
|
||||
2. Make sure your environment is set:
|
||||
$ source ${sgx-sdk-install-path}/environment
|
||||
3. Build the project with the prepared Makefile:
|
||||
a. Hardware Mode, Debug build:
|
||||
$ make
|
||||
b. Hardware Mode, Pre-release build:
|
||||
$ make SGX_PRERELEASE=1 SGX_DEBUG=0
|
||||
c. Hardware Mode, Release build:
|
||||
$ make SGX_DEBUG=0
|
||||
d. Simulation Mode, Debug build:
|
||||
$ make SGX_MODE=SIM
|
||||
e. Simulation Mode, Pre-release build:
|
||||
$ make SGX_MODE=SIM SGX_PRERELEASE=1 SGX_DEBUG=0
|
||||
f. Simulation Mode, Release build:
|
||||
$ make SGX_MODE=SIM SGX_DEBUG=0
|
||||
4. Execute the binary directly:
|
||||
$ ./app
|
||||
5. Remember to "make clean" before switching build mode

---------------------------
|

Purpose of LocalAttestation
|
||||
---------------------------
|
||||
The project demonstrates:
|
||||
- How to establish a protected channel
|
||||
- Secret message exchange using enclave to enclave function calls
|
||||
|
||||
------------------------------------
|
||||
How to Build/Execute the Sample Code
|
||||
------------------------------------
|
||||
1. Install Intel(R) Software Guard Extensions (Intel(R) SGX) SDK for Linux* OS
|
||||
2. Make sure your environment is set:
|
||||
$ source ${sgx-sdk-install-path}/environment
|
||||
3. Build the project with the prepared Makefile:
|
||||
a. Hardware Mode, Debug build:
|
||||
$ make
|
||||
b. Hardware Mode, Pre-release build:
|
||||
$ make SGX_PRERELEASE=1 SGX_DEBUG=0
|
||||
c. Hardware Mode, Release build:
|
||||
$ make SGX_DEBUG=0
