SpaceMac is a homomorphic MAC scheme that provides authentication for expanding spaces. This authentication mechanism can provide protection against pollution attack in network coding. In particular, SpaceMac can help with detecting the pollution attack as well as locating the attacker. Our security schemes built on SpaceMac are described in our publications.

Below are the implementations of SpaceMac in both Java and C/C++. Both implementations are provided as a ready-to-use library for anyone who is interested in providing subspace authentication in network coding. The Java library is Android OS compatible.

• Java library: SpaceMac.java
• C/C++ library: SpaceMac.cpp

Travel Grant Review Package (TravelGrantRP) is a management software that manages travel grant application submission and review processes. It is developed based on the open-source conference management software HotCRP. The current version of TravelGrantRP is 0.1.1, and is built based on HotCRP version 2.3.

TravelGrantRP is open source. Its installation requires about 15 minutes which involves setting up Apache, PHP, MySQL, and some PHP packages on your own server.

TravelGrantRP was initially developed for ACM SIGCOMM 2009 to assist professor Athina Markopoulou with managing the travel grants. By Oct 2011, it has been used for

• ACM IMC '09, '10, '11
• ACM SIGCOMM '09, '10, '11
• ACM CoNEXT '11

If you use TravelGrantRP for your conference/workshop grant application process, please drop me a line so I can update this list. Also, please let me know if you find any bugs.
