Protecting secret keys with personal entropy
Conventional encryption technology often requires users to protect a secret key by selecting a password or passphrase. While a good passphrase will only be known to the user, it a...

Tag-KEM/DEM: A New Framework for Hybrid Encryption
This paper presents a novel framework for the generic construction of hybrid encryption schemes which produces more efficient schemes than the ones known before. A previous framew...

Plaintext Awareness via Key Registration
Abstract. In this paper, we reconsider the notion of plaintext awareness. We present a new model for plaintext-aware encryption that is both natural and useful. We achieve plaintex...

Fully Homomorphic Encryption from Ring-LWE and Security for Key Dependent Messages
We present a somewhat homomorphic encryption scheme that is both very simple to describe and analyze, and whose security (quantumly) reduces to the worst-case hardness of problems ...

Generic Constructions of Parallel Key-Insulated Encryption
Exposure of a secret key is a significant threat in practice. As a notion of security against key exposure, Dodis et al. advocated key-insulated security, and proposed concrete k...
