ORAM

oram python implementation

implementation of server and client communicating via socket under:

• End to end encryption.
• ORAM protocol - to prevent statistical inference.
• Hash authentication - to validate the reliability of data

oram protocol based on the article Path ORAM.

Files

• Run server.py on the server. call Server.run() to run the server.
• With Client in client.py, You can write and read in the __name__ == "__main__" section, or write your own code and call to Client.read() and Client.write()
• In benchmarks.py you can find the code used to calculate the benchmarks appended.
• In clientAgent.py you can find the class ClientAgent, which responsible for all of the communication with the server, hashing, data authentication, and of course the ORAM module. As a user, you don't have any interaction with this file, unless you want to understand the code.
• block.py and bucket.py stands for the main data structures of the ORAM algorithm, for a bigger size of data in each block, you may need to change settings.RECEIVE_BYTES.
• settings.py contains all of the constants and data we supply to the program. change all from here.

Run

Just write $python3 server.py on the server, and $python3 client.py on the client.
