Dual System Encryption: Realizing Fully Secure IBE and HIBE under Simple Assumptions
We present a new methodology for proving security of encryption systems using what we call Dual System Encryption. Our techniques result in fully secure Identity-Based Encryption ...

Privacy Weaknesses in Biometric Sketches
The increasing use of biometrics has given rise to new privacy concerns. Biometric encryption systems have been proposed in order to alleviate such concerns: rather than comparing...

ID-based cryptography using symmetric primitives
A general method for deriving an identity-based public key cryptosystem from a one-way function is described. We construct both ID-based signature schemes and ID-based encryption ...

Key Distillation and the Secret-Bit Fraction
We consider distillation of secret bits from partially secret noisy correlations PABE, shared between two honest parties and an eavesdropper. The most studied distillation scenario...

New constructions of fuzzy identity-based encryption
In this paper we construct two new fuzzy identity-based encryption (IBE) schemes in the random oracle model. Not only do our schemes provide public parameters whose size is indepe...
