GSM Authentication - Mpirical

In this video taken from our GSM & GPRS system engineering course, we discuss two focus areas: Generating Authentication Vectors and the GSM Authentication Procedure.
This course explores the network architecture for both circuit and packet switched services, detailing the air interface and the initial procedures required for network access. Network usage is also explained, showing how calls, texts and data sessions are established and maintained as the subscriber moves around the network.

Just on point.. Wow!

[@jezyoo7]

very informative thank you so much

[@mohomedarfath4780]

well explained sir Thank you very much!!

[@saujolbagh2091]

Awesome explanation

[@oliviermesseumeni5450]

Well explained Thanks sir!

[@zomkarakaraul]

what is the use of Kc or cipher key generated here ? Not much details about it. Can you provide some more details about it too ?

[@Thori45]

Kc is not needed for the authentication, it is used after the authentication to feed another algorithm A5 to encrypt/decrypt the actual data

[@RohitShawshinobi]

Hi can you tell me if I want to change the cipher setting from A5/1 to A5/3 due to security reasons then in which device I will found this setting. I know this can be found in BSC nodes but no idea where in BSC nodes. Thanks

Nice video, the best I've found on the topic so far. However, there is still a detail unclear to me: is it not just the Ki, but a table of Ki/IMSI pairs being stored in the AuC?

[@Mpirical]

Thanks for your comment. The AuC maintains a relationship between a specific IMSI and an associated Ki value. Hence, when authentication credentials are requested at the AuC, the request must contain the IMSI so that the corresponding secret key can be accessed.
