International Association
for Cryptologic Research

The 4th International Conference on the Theory and Application of Cryptographic Techniques in Africa, AFRICACRYPT 2011, held July 5-7, 2011 in Dakar, Senegal. The Program Committee, aided by reports from 52 external reviewers, produced a total of 240 reviews in all. The 23 papers presented were carefully reviewed and selected from 76 submissions. They are organized in 10 topical sections on protocols, cryptanalysis, secret-key cryptography, efficient implementations, cryptographic schemes, algorithmic problems, elliptic curves, fault analysis, and security proofs. The program was completed with 3 invited talks by:

• Jens Groth on "Efficient Zero-Knowledge Proofs"
• Tatsuaki Okamoto on "Some Key Techniques on Pairing Vector Spaces" and
• Bart Preneel on "The NIST SHA-3 Competition: A Perspective on the Final Year"

The general chair was Mamadou Sanghare and the general co-chair was Djiby Sow. The program chair was David Pointcheval and the program co-chair was Abderrahmane Nitaj. The African paper entitled "On randomness extraction in elliptic curves" written by Abdoul Aziz Ciss and Djiby Sow was accepted as one of the best papers. The venue was at the AUF conference center next of Dakar University. There was about 90 attendees most of which stayed in hotels near the conference center (Djollof Hotel, Terroubi Hotel and University Hotel). The rump session was organized during the gala diner on the Wednesday at Terroubi Hotel. It was chaired by Peter Schwabe. The registration fee for normal attendees was 350 Euros (and 300 euros for PhDs students). General chair was Mamadou Sanghare, general co-chair was Djiby Sow.
