3. Title: **A Survey of Conditional Privacy Preserving Authentication for Internet of Vehicles**

4. Problem Description:
It is very difficult to  construct a secure authentication protocol which is conditional privacy preserving. Conditional privacy means that only trusted authority (TA) has the ability of identify the real identity of the Internet of vehicle (IoV) user. Existing ID-based cryptography cannot provide this property, so researchers must adopt more sophisticated cryptography such as group signature, hash chain or many more others. 

5. Reason to select the problem:
In the era of Internet, privacy becomes one of the most important issues. Internet of vehicle (IoV) is especially sensitive to privacy issue since IoV devices reveals much more sensitive data (like location data, which allows attacker to track users). While only preserving user privacy is not enough because we need to determine who is in charge when car accident happens, so we are interested in conditional privacy.

6. Rough Schedule:

| Date         | Schedule                            |
| ------------ | ----------------------------------- |
| 12/7 - 12/14 | Fully understand the existing works |
| 12/14 - 12/21| Find out the problems and make our own critiques|
|12/21 - 12/28| Improve the existing work by combining with new cryptography primitives|
|12/28 - 1/11| Write project report|

7. Expected Results: 
Fully understand the existing works. We will try to find some problems of them (about performance or potential threats). Finally, we will propose some methods to mitigate the existing problems probably by combining the existing protocols with new cryptographic primitives.
