Group-oriented Encryption Secure against Collude Attack
A group oriented encryption scheme is presented in this paper. In this scheme, a sender is allowed to encrypt a message using the group public key and send the ciphertext to the gr...

Efficient Constructions of Deterministic Encryption from Hybrid Encryption and Code-Based PKE
Abstract. We build on the new security notion for deterministic encryption (PRIV) and the PRIV-secure schemes presented by Bellare et al at Crypto'07. Our work introduces: 1) ...

A Cryptographically Sound Security Proof of the Needham-Schroeder-Lowe Public-Key Protocol
We prove the Needham-Schroeder-Lowe public-key protocol secure under real, active cryptographic attacks including concurrent protocol runs. This proof is based on an abstract crypt...

Provably secure ciphertext policy ABE
In ciphertext policy attribute-based encryption (CP-ABE), every secret key is associated with a set of attributes, and every ciphertext is associated with an access structure on a...
