1. An ultra-wideband (UWB) system comprising:
a memory in which a UWB ranging factor definition program is embedded; and
a processor which executes the program,
wherein the processor predefines UWB ranging factors for an encryption mode to define a nonce in consideration of a unique key characteristic of an individual device, wherein the nonce is generated based on source information;
wherein the processor further defines a scrambled timestamp sequence (STS) index and an encryption key.
