Bouncer: Admission Control Toolkit
We have implemented Bouncer, a general-purpose toolkit for admission control. All cryptographic functions are developed using the OpenSSL and MIRACL libraries. The toolkit is written in C on Linux 2.4 and currently consists of about 65,000 lines of codes.
System Architecture
The Bouncer toolkit is composed of three basic layers of the architecture; Bouncer APIs, security and management services, and the underlying cryptographic functions.
The Bouncer APIs define the application programming interface for accessing the admission control services. These APIs are useful when integrating our Bouncer with other peer group applications. The security and management services are carried out by the following modules:
- Policy Management Module
- Certificate Handling Module
- Data Encoding Module
- Protocol Handling Module
All security services are provided by the underlying cryptographic libraries. Most of the general cryptographic functions such as SHA-1, RSA, DSA, and so on, are supported by OpenSSL. Specifically, we have implemented three distributed cryptographic schemes on top of OpenSSL and MIRACL libraries, and embedded our libraries into it. The Bouncer supports five different threshold schemes; three for long-lived DPGs and two for short-lived DPGs.
1) Admission Protocols for Long-lived DPGs
TS-DSA
TS-Sch
ID-GAC (aka, TS-BLS)
2) Admission Protocols for Short-lived DPGs
UniAC (aka, PTKP or PSK)
BiAC
