This Type 1 TT&C provides both
Uplink and Downlink COMSEC
protection in a single compact
unit.
Uplink Algorithm:
– AES-256 (NIST FIPS-197)
Modes: GCM, ECB, CTR, and Features available for the first
CFB
time in a space crypto solution:
– Authenticated Command
< Multiple cryptographic
Modes: GCM and ECB with
modes and flexible
VCC (Vehicle Command Count)
synchronization logic
support many mission
Downlink Encryptor Algorithm:
profiles and CONOPS
– Fail-Safe Redundant AES-256
Modes: GCM, CTR, and CFB
< GCM cryptographic mode
– Random number generator
supports variable length
(RNG) for initial vector
authenticated commands up
generation
to 32k bytes in length
Over-the-Air Rekey (OTAR):
< Integrity verification
– AES-256 ECB per KMI 3240
downlink option is ideal for
Key Wrap Spec
tactical applications, such as
– In-band or in-flight transferring
UHF radios
of black key
<
Multiple authenticated
command channels enable
direct payload or satellite
tasking from tactical and/or
multiple users
<
Highly integrated single chip
embedded ASIC within the
AVE reduces footprint and
