end-to-end

End-to-end evaluation of latency

This part compares the end-to-end latency of an auction from the browser sending invitation requests to bidders until the auction server finishes computing the auction.

The evaluation consists of the non-private baseline where all bids are sent in clear to auction server and Ibex's oblivious bidding protocol.

Ibex's oblivious bidding protocol

How to build

cmake . -B build
cd build
make -j

How to run

Setup

• Establish the SSH keyless connections from your client machine to all other machines of bidders and auction servers. Make sure you have connected once from your client machine to all other machines to establish authenticity.
• On all other machines, build the programs correctly.

Edit config files

• Edit the variable ips in stop-bidders.sh and run-bidders.sh, change it to the the ips of the bidders machine. We assume using c5.24xlarge instances, so each server simulate 6 bidders.
• Edit the variable ips, ip1, and ip2 in stop-auction-servers.sh and start-auction-servers.sh, change it to the the ips of the two auction servers.
• Copy all files in files directory into build/ directory on all machines where the bidder and client programs exist.
• Copy all scripts in script directory into build/ directory on all machines where the bidder and client programs exist.

Start the bidders

• On the client machine, run bash run-bidders.sh [user name] [logarithm of total group] [path of bidder program].
  • user name is the user name you used to log into your bidders machine.
  • logarithm of total group, for example, is set to 15 for $2^{15}$ groups.
  • [path of bidder program] is the path on the bidder servers where the bidder program is. For example, it could be ibex/bidding/end-to-end/ibex-bidding/build/

Start the auction servers

• On the client machine, run bash run-auction-servers.sh [user name] [bidder number] [path of bidder program].
  • user name is the user name you used to log into your bidders machine.
  • [path of bidder program] is the path on the bidder servers where the auctioneer program is. For example, it could be `ibex/bidding/end-to-end/ibex-bidding/auctioneer/build/bin``.

Start the client

• On the client machine, copy ips.txt into build/ directory and modify ips.txt accordingly.
  • The format of ips.txt is IP:PORT in each line
  • The first two lines are ip addresses of the two auction servers.
  • Afterwards each line represents a bidder's PIR server.
• On the client machine, run ./client -b [bidder number] -l [logarithm of total group].

Stop auctioneer and bidders

• After each run, on the client machine, run bash stop-auction-servers.sh [user name] and bash stop-bidders.sh [user name].

Non-private baseline

How to build

cmake . -B build
cd build
make -j

How to run

• Copy cert.pem and key.pem in files directory into build directory.
• Each line in ips.txt represents a bidder, in the format of IP:PORT. The auctioneer program will read the IP addresses of bidders from this file, please change it accordingly and copy it into the build directory.
• On the bidder machine, copy start-bidders.sh into the build directory. Run bash start-bidders.sh [bidder number] to start the bidders programs which starting listening from port 6666 to 6666+[bidder number].
• On the auctioneer machine, run ./auctioneer [bidder number] to start the auctioneer program and listening on the port 5555.
• On the client machine, run ./client [auctioneer IP]. auctioneer IP is in the format of IP:PORT. The client program will output the total latency.
