A report published Oct. 27, 2026 by MIT News described a Protected Anti-Jam Tactical Satcom (PATS) Key Management System (KMS) Prototype developed by MIT Lincoln Laboratory. According to the report, the architecture was designed to refresh cryptographic keys quickly across terminals dispersed worldwide, including in contested or bandwidth-constrained environments. Lincoln Laboratory researchers were quoted explaining that the prototype was being adopted as the cryptographic backbone of the U.S. Space Force's next-generation PATS satcom system and would serve as a reference implementation for an industry-built operational KMS, with sponsorship from the Space Force's Space Systems Command.

The report said the prototype combines a monthly "pull" of keys tailored to each terminal with a daily "push" of a smaller key, creating layered security and addressing offline devices. It also said the team adapted broadcast encryption to send daily keys to many terminals while preserving bandwidth. The article states that last year the first PATS end cryptographic unit, the space-hub ECU, earned National Security Agency certification, and that the SSC and Lincoln Laboratory team received a 2025 R&D 100 Award.

The report described these as developments as of its publication date and did not establish a timeline for full operational deployment.
