\n\n\n\n## What is Java and SGX?\n\n> Java was originally developed as an alternative to the C/C++ programming languages. It is now mainly used for building web, desktop, mobile, and embedded applications. Java is owned and licensed through Oracle, with free and open source implementations available from Oracle and other vendors.\n\n[Overview of Java](https://www.java.com/)\n\n> Intel Security Guard Extension (SGX) delivers advanced hardware and RAM security encryption features, so called enclaves, in order to isolate code and data that are specific to each application. When data and application code run in an enclave additional security, privacy and trust guarantees are given, making the container an ideal choice for (untrusted) cloud environments.\n\n[Overview of Intel SGX](https://www.intel.com/content/www/us/en/developer/tools/software-guard-extensions/overview.html)\n\nApplication code executing within an Intel SGX enclave:\n\n- Remains protected even when the BIOS, VMM, OS, and drivers are compromised, implying that an attacker with full execution control over the platform can be kept at bay\n- Benefits from memory protections that thwart memory bus snooping, memory tampering and “cold boot” attacks on images retained in RAM\n- At no moment in time data, program code and protocol messages are leaked or de-anonymized\n- Reduces the trusted computing base of its parent application to the smallest possible footprint\n\n\n## Why use Java-SGX (instead of \"vanilla\" Java) images?\nFollowing benefits come for free with Java-SGX :\n\n* Protect Java data, files, applications, services, APIs, (AI) models against intelectual property theft/violation irrespectively where the application runs thanks to full fledge memory container encryption and integrity protection at runtime\n* Shield container application against container escape attacks with hardware-graded security against kernel-space exploits, malicious and accidental privilege [insider](https://www.ibm.com/topics/insider-threats) attacks, [UEFI firmware](https://thehackernews.com/2022/02/dozens-of-security-flaws-discovered-in.html) exploits and other \"root\" attacks using the corruption of the application to infiltrate your network and system\n* Build and deploy Java application as usual while inheriting literally for free security and privacy through containerization including\n * strictly better TOMs (technical and organizatorial measures)\n * privacy export regulations compliant deployment anywhere, such as [Schrems-II](https://www.europarl.europa.eu/RegData/etudes/ATAG/2020/652073/EPRS_ATA(2020)652073_EN.pdf)\n * GDPR/CCPA compliant processing (\"data in use\") of user data (in the cloud) as data is relatively anonymized thanks to the enclave\n\n \n## TL;DR\n\n```sh\ndocker pull enclaive/java-sgx\ndocker-compose up -d\n```\n**Warning**: This quick setup is only intended for development environments. You are encouraged to change the insecure default credentials and check out the available configuration options in the [build](#build-the-image) section for a more secure deployment.\n\n\n\n## How to deploy Java-SGX in a zero-trust cloud?\n\nThe following cloud infrastractures are SGX-ready out of the box\n* [Microsoft Azure Confidential Cloud](https://azure.microsoft.com/en-us/solutions/confidential-compute/) \n* [OVH Cloud](https://docs.ovh.com/ie/en/dedicated/enable-and-use-intel-sgx/)\n* [Alibaba Cloud](https://www.alibabacloud.com/blog/alibaba-cloud-released-industrys-first-trusted-and-virtualized-instance-with-support-for-sgx-2-0-and-tpm_596821) \n* [Kraud Cloud](https://kraud.cloud/)\n\nConfidential compute is a fast growing space. Cloud providers continiously add confidential compute capabilities to their portfolio. Please [contact](#contact) us if the infrastracture provider of your preferred choice is missing.\n\n\n## Getting started\n### Platform requirements\n\nCheck for *Intel Security Guard Extension (SGX)* presence by running the following\n```\ngrep sgx /proc/cpuinfo\n```\nAlternatively have a thorough look at Intel's [processor list](https://www.intel.com/content/www/us/en/support/articles/000028173/processors.html). (We remark that macbooks with CPUs transitioned to Intel are unlikely supported. If you find a configuration, please [contact](#contact) us know.)\n\nNote that in addition to SGX the hardware module must support FSGSBASE. FSGSBASE is an architecture extension that allows applications to directly write to the FS and GS segment registers. This allows fast switching to different threads in user applications, as well as providing an additional address register for application use. If your kernel version is 5.9 or higher, then the FSGSBASE feature is already supported and you can skip this step.\n\nThere are several options to proceed\n* If: No SGX-ready hardware
\n[Azure Confidential Compute](https://azure.microsoft.com/en-us/solutions/confidential-compute/\") cloud offers VMs with SGX support. Prices are fair and have been recently reduced to support the [developer community](https://azure.microsoft.com/en-us/updates/announcing-price-reductions-for-azure-confidential-computing/). First-time users get $200 USD [free](https://azure.microsoft.com/en-us/free/) credit. Other cloud provider like [OVH](https://docs.ovh.com/ie/en/dedicated/enable-and-use-intel-sgx/) or [Alibaba](https://www.alibabacloud.com/blog/alibaba-cloud-released-industrys-first-trusted-and-virtualized-instance-with-support-for-sgx-2-0-and-tpm_596821) cloud have similar offerings.\n* Elif: Virtualization
\n Ubuntu 21.04 (Kernel 5.11) provides the driver off-the-shelf. Read the [release](https://ubuntu.com/blog/whats-new-in-security-for-ubuntu-21-04). Go to [download](https://ubuntu.com/download/desktop) page.\n* Elif: Kernel 5.9 or higher
\nInstall the DCAP drivers from the Intel SGX [repo](https://github.com/intel/linux-sgx-driver)\n\n ```sh\n sudo apt update\n sudo apt -y install dkms\n wget https://download.01.org/intel-sgx/sgx-linux/2.13.3/linux/distro/ubuntu20.04-server/sgx_linux_x64_driver_1.41.bin -O sgx_linux_x64_driver.bin\n chmod +x sgx_linux_x64_driver.bin\n sudo ./sgx_linux_x64_driver.bin\n\n sudo apt -y install clang-10 libssl-dev gdb libsgx-enclave-common libsgx-quote-ex libprotobuf17 libsgx-dcap-ql libsgx-dcap-ql-dev az-dcap-client open-enclave\n ```\n\n* Else: Kernel older than version 5.9
\n Upgrade to Kernel 5.11 or higher. Follow the instructions [here](https://ubuntuhandbook.org/index.php/2021/02/linux-kernel-5-11released-install-ubuntu-linux-mint/). \n\n### Software requirements\nInstall the docker engine\n```sh\n sudo apt-get update\n sudo apt-get install docker-ce docker-ce-cli containerd.io\n sudo usermod -aG docker $USER # manage docker as non-root user (obsolete as of docker 19.3) \n```\nUse `docker run hello-world` to check if you can run docker (without sudo).\n\n\n## Get this image\n\nThe recommended way to get the enclaive Java-SGX Open Source Docker Image is to pull the prebuilt image from the [Docker Hub Registry](https://hub.docker.com/r/enclaive/rust-sgx).\n\n```console\ndocker pull enclaive/java-sgx:latest\n```\n\nTo use a specific version, you can pull a versioned tag. You can view the\n[list of available versions](https://hub.docker.com/r/enclaive/java-sgx/tags/)\nin the Docker Hub Registry.\n\n```console\ndocker pull enclaive/java-sgx:[TAG]\n```\n\n\n## Build the image\nIf you wish, you can also build the image yourself.\n\n```console\ndocker build -t enclaive/java-sgx:latest 'https://github.com/enclaive/enclaive-docker-java-sgx.git#master'\n```\n\nThe build consists of two stages. The first (\"builder\") stage uses Gradle to build the Gradle-based [Java project](src/project) and creates a runnable JAR. The second (\"gramine\") stage gathers all the necessary resources and signs the manifest based on the [existing template](java.manifest.template).\n\n## Modify the image\n\n### Gradle-based JVM application\nReplace the `project` folder, at `src/project`, with your Gradle-based project and change the referenced folders and Gradle tasks inside the builder stage in the Dockerfile accordingly.\n\n### Non-Gradle-based JVM application\nReplace the `project` folder, at `src/project`, with your JVM application project and exchange the builder stage inside the Dockerfile with your needed build config. Make sure to copy the resulting jar to the root folder of your builder stage and for convenience name it `enclave.jar`. This way you most likely won´t have to touch the second stage.\n\n\n## Run the image\nRun\n``\ndocker-compose up -d\n``\nto start the Java application.\n\n\n## Contributing\n\nContributions are what make the open source community such an amazing place to learn, inspire, and create.
