Full Description
Africacrypt 2010, the Third International Conference on Cryptology in Africa, took place May 3-6, 2010 in Stellenbosch, South Africa. The General Chairs, Riaal Domingues from the South African Communications and Security Agency and Christine Swart from the University of Cape Town, were always a pleasure to work with and did an outstanding job with the local arrangements. We are deeplythankfulthat theyagreedto hostAfricacrypt2010with onlyfour months notice after unanticipated events forced a change of location. The Africacrypt 2010 submission deadline was split into two. Authors s- mitting paperswererequiredto registertitles andabstractsby the ?rstdeadline, January 5. A total of 121 submissions had been received by this deadline, - though some were withdrawn before review. Authors were allowed to continue working on their papers until the second deadline, January 10. Submissions were evaluated in three phases over a period of nearly two months. The selection phase started on January 5: Program Committee m- bers began evaluating abstracts and volunteering to handle various papers. We assigned a team of people to each paper.
The review phase started on January 11: Program Committee members were given access to the full papers and - gan in-depth reviews of 82 submissions. Most of the reviews were completed by February7,thebeginningofthediscussionphase.ProgramCommitteemembers were given access to other reviews and built consensus in their evaluations of the submissions. In the end the discussions included 285 full reports and 203 - ditional comments. The submissions, reviews, and subsequent discussions were handled smoothly by iChair.
