A Tapestry of Identity-Based Encryption: Practical Frameworks Compared

By Xavier Boyen.

In International Journal of Applied Cryptography, volume 1, number 1, pages 3-21. Inderscience, 2008.

Invited inaugural article.


This paper surveys the practical benefits and drawbacks of several identity-based encryption schemes based on bilinear pairings. After providing some background on identity-based cryptography, we classify the known constructions into a handful of general approaches. We then describe efficient and fully-secure IBE and IBKEM instantiations of each approach, with reducibility to practice as the main design parameter. Finally, we catalogue the strengths and weaknesses of each construction according to a few theoretical and many applied comparison criteria.
