Privacy Preserving Threat Intelligence

PPTI is research project.

As modern threats become more sophisticated, it is imperative for organizations to defend with the global context. Many cloud based services provide threat intelligence pertaining to modern advanced persistent threats (APTs). Cloud services such as: Google Safe Browsing, PhishTank, and Malwr offer black lists of known malicious URLs, domains, emails etc. Querying such services require users to share their browsing history and files in order to know whether their machines got infected or not. One of the major concerns/ hindrances remained to be addressed to benefit from such services is the users’ privacy.

Current implementation of PPTI has only Private Similar Document Retrieval(PSDR) scheme called COSIMP. PPTI uses JPIR library (https://github.com/sashank/jpir)

The complete paper would be made available soon.

REST based Client/Server communication is supported for private queries

Usage :

JPIR Setup :

Download or git clone the project JPIR change directory to jpir Run the below command on your terminal to generate PIRServer.jar

mvn clean install
mv target/jpir-1.0-SNAPSHOT-jar-with-dependencies.jar PIRServer.jar

PPTI Server Setup :

Download or git clone the project PPTI change directory to PPTI and configure pom.xml with jpir.jar's location Run the below command on your terminal to generate PPTIServer.jar

mvn clean install
mv target/ppti-1.0-SNAPSHOT-jar-with-dependencies.jar PPTIServer.jar

1. Copy the PPTIServer.jar file to some server.
2. Copy the server.properties to the server
3. Modify the server.properties with appropriate input file (as database)
4. Run the below command to start the server java -jar PPTIServer.jar

Client Setup :

5. Update the client.properties with Server's IP Address
6. From your IDE just run the PIR_RestClient.java
7. For running it from command line 8. Change the main file in pom.xml with PPTIClient 9. mvn clean install 10. mv target/ppti-1.0-SNAPSHOT-jar-with-dependencies.jar PPTIClient.jar 11. java -jar PPTIClient.jar (Will execute the client) The output would be printed on the console.
