The Fifth International Conference on Provable Security (ProvSec 2011) will be held in Xi'an, China on October 16-18, 2011. It will be co-organized by Xidian University.

Provable security is an important research area in modern cryptography. Cryptographic primitives or protocols without a rigorous proof cannot be regarded as secure even in practice. In fact, there are many schemes that were originally thought as secure but eventually broken, which clearly indicates the need of formal security assurance. With provable security, we are confident in using cryptographic schemes and protocols in various real-world applications. Meanwhile, schemes with provable security sometimes give only theoretical feasibility rather than a practical construction, and correctness of the proofs may be difficult to verify. ProvSec conference thus provides a platform for researchers, scholars and practitioners to exchange new ideas for solving these problems in the provable security area.

Topics include all aspects of provable security for cryptographic primitives or protocols, and include but are not limited to the following areas:

• Cryptographic primitives
• Security notions, approaches, and paradigms
• Formal security model
• Secure cryptographic protocols and applications
• Provable secure block ciphers and hash functions
• Digital signatures
• Privacy and anonymity technologies
• Steganography and steganalysis
• Lattice-based security reductions
• Pairing-based provably secure cryptography
