2025 eCTF

Welcome to the 2025 eCTF!

This year, teams will design and implement a Satellite TV System solution. The system must securely encode and decode satellite TV data streams while protecting against unauthorized access to protected channels. Teams will design both the Encoder that will encode TV frames to be broadcast over the satellite in real-time to all teams as well as the hardware Decoder responsible for securely decoding frames for display on the TV.
