TitleBreaking an identity-based encryption scheme based on DHIES.
Author(s) Martin R. Albrecht, Kenneth G. Paterson
TypeBook, Chapter in Book, Conference Proceeding
AbstractWe present collusion attacks against a recently proposed IBE scheme of Chen et al. from ASIACCS 2010. The attacks recover the master secret key of the scheme and thereby invalidate the existing security analysis of this scheme. The attacks are flexible, allowing, for example, the amount of computation needed to be traded-off against the size of the collusion.
