Efficient Cryptographic Authorization for AI Agents
Tenuo is a robust cryptographic authorization framework designed for AI agents, offering a flexible and secure way to manage permissions through capability tokens known as warrants. With its unique holder-bound approach, Tenuo ensures that stolen tokens cannot be misused without the corresponding cryptographic key. The system verifies authorization checks offline in under 50 microseconds, enhancing performance by eliminating the need for network calls during execution. This feature is particularly useful in high-demand environments where latency is critical.
The framework is built on the principle of subtractive delegation, allowing capabilities to be narrowed but never expanded, which mitigates security risks associated with session roles and delegation chains. Tenuo supports various integrations, including OpenAI and Google ADK, making it versatile for teams implementing tool-calling and multi-agent workflows. Its design emphasizes a deterministic authorization boundary at agent speed, making it a valuable tool for developers seeking to enhance security in AI applications.
