Adaptively Secure Recipient Revocable Broadcast Encryption with Constant size Ciphertext
recipient revocable broadcast encryption chosen plaintext attack adaptive security
2017/2/20
In this paper, we put forward the first adaptively secure recipient revocable broadcast encryption (RR-BE) scheme in the standard model. The scheme is adaptively secure against chosen plaintext attack...

2016/1/8
A Hidden Vector Encryption (HVE) scheme is a special type of anonymous identitybased
encryption (IBE) scheme where the attribute string associated with the ciphertext or the
user secret key can cont...
Private Ciphertext-Policy Attribute-based Encryption Schemes With Constant-Size Ciphertext Supporting CNF Access Policy

Attribute-based encryption (ABE) is an extension of traditional public key encryption in which
the encryption and decryption phases are based on user’s attributes. More precisely, we focus on ciphert...

We present a Hierarchical Identity Based Encryption (HIBE) system where the ciphertext
consists of just three group elements and decryption requires only two bilinear map computations,regardless of t...
Constant Size Ciphertext HIBE in the Augmented Selective-ID Model and its Extensions
Constant Size Ciphertext HIBE Augmented Selective-ID Model Extensions
2008/9/10
At Eurocrypt 2005, Boneh, Boyen and Goh presented a constant size ciphertext hierarchical
identity based encryption (HIBE) protocol. Our main contribution is to present a variant of the
BBG-HIBE.
