Secure ECC-based DID intersection.

This project is used to protect device ID using Elliptic Curve Cryptography algorithm. The details of this project can be found inINTRODUCTION.

For Golang User

go get -u github.com/volcengine/SecureUnionID

For Java UserThe Java source code is under the bindings/java directory.

Please see theREADME.md under the bindings/java directory.

For Golang User

We provide three demos without http communication (/bingdings/go/demo/demo.go, /bingdings/go/demo/demo1.go, /bingdings/go/demo/demo2.go). Run demo with the following command：

go run demo.gogo run demo1.gogo run demo2.go

We also provide a demo with http communication (/bingdings/go/httpdemo/http_client_demo.go, /bingdings/go/httpdemo/http_sever_demo.go). Run this demo with the following command in two terminals:

go run http_client_demo.go

go run http_sever_demo.go

For Java User

Please see theREADME.md under the bindings/java directory.

We provide a benchmark file for Golang user, the path of which is /bindings/go/benchmark/benchmark.go. The performance on a 2.3 GHz core i7, 32G DDR4 mac with 2 media is as follows:

GenMasterKey -    35572 iterations       0.28 ms per iterationKeyGen -    13785 iterations       0.73 ms per iterationSystemKeygen -    87311 iterations       0.11 ms per iterationBlindv2 -    16344 iterations       0.61 ms per iterationEnc -    43323 iterations       0.23 ms per iterationUnblind -    34110 iterations       0.29 ms per iterationVerify -     5111 iterations       1.96 ms per iteration

We provide API documents ofC,Go,Java,Python (English version inC_EN,Go_EN,Java_EN,Python_EN). Other contributors can develop interfaces in other languages according to this document.
