1 LTE Security Encryption and Integrity Protection in LTE 2012 Inc. 1

2 LTE Security: ey Concepts Authentication The LTE Network verifies the UE s identity by challenging the UT use the keys and report a result. The network checks the result against the expected result Integrity Signaling message receiver verifies that the received message is exactly the message that the transmitter sent This is done using an integrity checksum Guards against man in the middle attacks where the senders messages and intercepted by a hacker and a modified message is relayed to the receiver Encryption The sender encrypts the data with a secret key that is only known to the receiver Only the receiver is able to decode the message Guards against hackers listening in on the data 2012 Inc. 2
