No, IIRC it isn't anywhere near real encryption.

- nicce 3y agoHmm… LTE stands for 4G and they use 128-EEA2 (AES-CTR) or 128-EIA2 (AES-CMAC) which are kinda same as TLS 1.2 and TLS 1.3. Where the latter suppors chacha additionally. GCM on TLS gives greater performance and the integrity can be confirmed earlier, but there are no serious security problems on algorithm side.
- bryancoxwell 3y agoImportant to note that the encryption you mention applies to user data traveling between the UE and the eNodeB. Some control plane data between the UE and eNB is unencrypted and no encryption of user data is done between the eNB and the network (unless it’s done at a higher layer).
- jiggunjer 3y agoNah, 4g stands for 4g.
- nicce 3y agoLTE is industry jargon for the fastest type of 4G
