Keylime

Overview:

Keylime is an open-source trust system that leverages TPM (Trusted Platform Module) Technology to establish hardware-rooted cryptographic trust for remote machines. It offers solutions for bootstrapping, provisioning encrypted payloads, and monitoring system integrity in real-time. Keylime aims to simplify TPM Technology accessibility for developers and users without requiring an in-depth understanding of TPM operations. It is particularly useful for scenarios like remote attestation in hybrid cloud environments or securing Edge/IoT devices in vulnerable locations.

Features:

• Scalable Trust System: Utilizes TPM Technology for establishing trust in remote machines.
• End-to-End Solution: Provides solutions for bootstrapping, encryption provisioning, and real-time integrity monitoring.
• Customized Actions: Users can define actions triggered when a machine fails its attested measurements.
• Flexible Remote Attestation: Offers a flexible framework for remote attestation of Platform Configuration Registers (PCRs).
• CLI Application and RESTful APIs: Allows interaction with Keylime through a CLI application and RESTful APIs.
• Components: Consists of three main components - Verifier, Registrar, and Agent.

Summary:

Keylime is an open-source trust system that simplifies the usage of TPM Technology for remote machine attestation and provisioning. With features like end-to-end solutions, customizable actions, and flexible remote attestation, Keylime offers a secure and scalable trust system. It is developed primarily in Python with the Agent component ported to Rust for improved performance and security. It is crucial to use hardware TPMs instead of software emulators while deploying Keylime for enhanced security. Users can follow the installation guide to set up Keylime and start utilizing its features for secure remote machine operations.
