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)
