Reducing Multilinear Map Levels in Constrained PRFs and ABE
Constrained PRFs multilinear maps ABE
font style='font-size:12px;'>
2015/12/23
The candidate construction of multilinear maps by Garg, Gentry, and Halevi (Eurocrypt
2013) has lead to an explosion of new cryptographic constructions ranging from attribute-based encryption
(ABE) ...
Hierarchical Identity Based Encryption with Polynomially Many Levels
Hierarchical Identity Encryption Polynomially Many Levels
font style='font-size:12px;'>
2009/6/9
We present the first hierarchical identity based encryption (HIBE) system that has full
security for more than a constant number of levels. In all prior HIBE systems in the literature, the
security ...
A Suite of ID-Based Threshold Ring Signature Schemes with Different Levels of Anonymity
ID-Based Cryptography Ring Signature Anonymity Linkability
font style='font-size:12px;'>
2009/3/5
Since the introduction of Identity-based (ID-based) cryptography
by Shamir in 1984, numerous ID-based signature schemes have
been proposed. In 2001, Rivest et al. introduced ring signature that prov...
PAIRING-BASED CRYPTOGRAPHY AT HIGH SECURITY LEVELS
public key cryptography elliptic curve Weil pairing Tate pairing
font style='font-size:12px;'>
2009/1/20
In recent years cryptographic protocols based on the Weil
and Tate pairings on elliptic curves have attracted much attention. A no-
table success in this area was the elegant solution by Boneh and F...
