Abstract

Den foreliggende oppfinnelse vedrører en fremgangsmåte og system for å utlede krypteringsnøkkel ved hjelp av felles tilfeldighet ikke delt med andre (JRNSO). Kommuniserende enheter danner JRNSO bit fra et kanalimpulsrespons (CIR) estimat og JRNSO bitene brukes i dannelsen av en krypteringsnøkkel. Autentifiseringstypen kan være IEEE 802.I x eller et forhåndsdelt nøkkel system. I et IEEE 802.I x system dannes en hovednøkkel, en parvis hovednøkkel eller en parvis transient nøkkel ved hjelp av JRNSO bitene. Krypteringsnøkkelen kan utledes ved å bruke en Diffie-Hellman nøkkelutledningsalgoritme.The present invention relates to a method and system for deriving encryption key by means of shared randomness not shared with others (JRNSO). Communicating units generate JRNSO bits from a channel impulse response (CIR) estimate and JRNSO bits are used in the formation of an encryption key. The authentication type can be IEEE 802.I x or a pre-shared key system. In an IEEE 802.I x system, a master key, a pair master key or a pair transient key is generated using the JRNSO bits. The encryption key can be derived using a Diffie-Hellman key derivation algorithm.
