The miniature COMSEC unit (MCU-110C) is an integrated encryptor/decryptor unit providing secure uplink and downlink protection for satellite communications links. The MCU-110C is the next generation configuration of the legacy MCU-110B with over 130 units delivered and 100% on-orbit success. The MCU-110C utilizes the Carousel algorithm for uplink decryption up to 5 Mbps and supports loading of 256-selectable keys either electronically or through OTAR. The Pegasus ASIC is used for downlink encryption up to 10 Mbps with and supports loading of 256-selectable keys in MRAM either electronically or through OTAR.
The MCU-110C includes both uplink and downlink over the air rekeying (OTAR) and downlink error-correction (convolutional encoding) that is enabled by the user, if required. The MCU-110C design is radiation- hardened for missions up to 15 years.
L3Harris Telemetry & RF Products (T&RF) has a rich heritage of flight-proven satellite products. With over 25 years of experience, we have embedded a variety of National Security Agency (NSA) devices, including AES-256, Caribou, Cardholder and BELSHAZZAR algorithms into high-reliability space applications.
