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?

March2018 4Project25TechnologyInterestGroup

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)
