Secure Group Communication

Managing Group Keys and Securing Data using MLS

With new regulations like the Digital Market Act, companies now have to embrace interoperability, especially when it comes to communications and messaging. The new standard that the industry is converging on is the IETF MLS protocol. We are experts in MLS and have contributed a formal security analysis, reference implementation, and improvements to the standard. We help maintain OpenMLS, a flagship Rust implementation of MLS.

Cryspen can help you embrace this new standard, and integrate it into your technology stack. We provide custom variants and extensions that might be more efficient and better suited to your deployment scenarios. We develop new components based on MLS, such as a key management service. We help our customers formally analyze and precisely document their extensions to MLS and prepare them for a possible standardization.
