CYZ 10VINSON architecture- encryption algorithm

•Loadset:= TSK- Transmission Security Key

•TEK- Traffic Encryption Key- for Voice and data•KEK- Key encryption key- for OTAR

PLGR (Precision

Lightweight GPS Reciever)

•Used to fill all current military field radios with time for crypto- hopping purposes. •Also a GPS•Bulky, and fills extra spaceCan take up to 3 minutes to aquire time and position- slow!

PRC- 119PRC-119

•Mobile applications & man pack applications•VHF 30-87.975 MHz •Range 3- 25 Km depending on setup (man pack or vehicular PA)Capabilities•Baud Rate= 600, 1200, 2400, 4800 and 16,000 bps (power setting, setup)
