PTIGP25Update


LinkLayerEncryption(LLE)ProblemStatement

•  P25 Link Layer Encryption helps ensure the following: o  Integrity – How can you know the message has not

been altered in some way? o  Specifically Replay Protection ensures that a message

cannot be resent later by an untrusted source. o  Confidentiality – How can you be sure that the

message is only received by the intended parties o  Key Distribution - Do the initiating and receiving

parties have the means to securely communicate?


LLEProblemStatement

•  P25 End-to-End Encryption for voice calls and packet data protects the contents of the transmission

•  End-to-End Encryption by itself does NOT protect against intercepting the identities of the parties involved in a call •  Initiator of a Call (Typically a User ID) •  Target of a Call (Typically a Group ID but may be a Supergroup or

another User ID)

KeyFillDevice(KFD)AddendumScope

•  EnhancesinteroperabilityforP25encryptionbyprovidingstandards-basedinterfacesbetweenaKeyFillDevice(KFD)andthefollowing:o AKeyManagementFacility(KMF)

o AnAuthenticationFacility(AF)o ALinkEncryptionFacility(LEF)o AnotherKFD


KFDAddendumUserConsiderations

•  TODAY:InterfacesbetweenKMF,AF,andKFDandtheKFDareproprietary.ThispresentschallengesforinteroperabilitybetweendifferentP25manufacturers.

•  ThereisnoimpactontheinterfacebetweentheKMFandSUwiththischange.Shouldallowsupportforlegacydeviceswithnew/updatedKFDs.

P25AuthenticationProblemStatement

•  P25AuthenticationHelpsEnsure:o OnlyAuthorizedRadiosObtainServiceonaTrunkingSystem

o ReducestheRisktoPublicSafetyCommunicationSystemsArisingFromPiratedSystemKeysorProgrammingSoftwareo ReducesthePossibilityofDuplicateRadioIDso ImprovesProtectionFromLostorStolenRadios


P25LinkLayerAuthenticationUserConsiderations

–  UniqueAuthenticationKeyForEachSystemandRadioID

o AuthenticationIsUsuallyPartofRegistration,ButCanOccuratAnytime

o DisablingtheKeyIntheAuthenticationServerWillPreventanUnaccountedforRadioFromGainingSystemAccess

o Utilizes128BitAESEncryption–  3.4X1038KeyValues–  FIPS-140-2Approved
