A Hybrid PKI-IBC Based Ephemerizer System
The concept of an Ephemerizer system has been introduced in earlier works as a mechanism to ensure that a file deleted from the persistent storage remains unrecoverable. The princ...

Public-Key Cryptosystems Resilient to Key Leakage
Most of the work in the analysis of cryptographic schemes is concentrated in abstract adversarial models that do not capture side-channel attacks. Such attacks exploit various for...

Signature Schemes and Anonymous Credentials from Bilinear Maps
Abstract. We propose a new and efficient signature scheme that is provably secure in the plain model. The security of our scheme is based on a discrete-logarithm-based assumption p...

Practical leakage-resilient identity-based encryption from simple assumptions
We provide new constructions of Leakage-Resilient IdentityBased Encryption systems (IBE) in the Standard model. We apply a hash proof technique in the existing IBE schemes of Bone...
