I need to do an assignment on GSM Security. I need help from you people. Which security techniques are used in GSM security, the cryptography, algorithm, keys, about all this.
Please if you people have any papers, document, or web link so share it with me.

I don't understand the question.
In GSM there is the AuC node which assures that the events (calls, SMS, SS invocations etc) are ciphered and encrypted. You can find plenty of information on the internet. What else do you need about the security?

I donot think AUC mode ensure the encryption of the events, but it ensures the Authentication of the user, validity of the user.
I need GSM security papers that can explain the alogritms used such as; A3, A5, A8.

Well not the AUC but the algorithm stored there and in the SIM.
Specs for A3/A8 can be found in 3GPP TS 43.020.
