Function-Private Identity-Based Encryption: Hiding the Function in Functional Encryption
public-key cryptography
2014/3/13
We put forward a new notion, function privacy, in identity-based encryption and, more generally, in functional encryption. Intuitively, our notion asks that decryption keys reveal essentially no infor...
Efficient Delegation of Key Generation and Revocation Functionalities in Identity-Based Encryption
public-key cryptography / identity-based encryption revocation delegation
2013/2/21
In the public key cryptosystems, revocation functionality is required when a secret key is corrupted by hacking or the period of a contract expires. In the public key infrastructure setting, numerous ...
Revocable Identity-Based Encryption Revisited: Security Model and Construction
public-key cryptography / identity-based encryption revocation decryption key exposure
2013/2/21
In ACM CCS 2008, Boldyreva et al. proposed an elegant way of achieving an Identity-based Encryption (IBE) with {\em efficient} revocation, which we call revocable IBE (RIBE). One of the significant be...

Public-key cryptography / Identity-based encryption bilinear maps
2013/2/21
We present a new practical Identity-Based Encryption (IBE) system that can be another candidate for standard IBE techniques. Our construction is based on a new framework for realizing an IBE trapdoor ...

2012/3/27
Cryptosystems based on the hardness of lattice problems have recently acquired much importance due to their average-case to worst-case equivalence, their conjectured resistance to quantum cryptanalysi...

Breaking An Identity-Based Encryption Scheme based on DHIES
An Identity-Based Encryption Scheme DHIES
2010/12/16
We present collusion attacks against an Identity-based Encryption scheme based on DHIES that was proposed by Chen et al. at ASIACCS 2010. Our attacks recover the master secret key of the scheme, so in...

2010/10/11
Identity based encryption(IBE) have been received great attention since Boneh and Franklin's breakthrough work on IBE by using bilinear groups. Till now, many IBE schemes relying on bilinear maps with...
Remarks about the Security Proofs of Boneh-Franklin’s Identity-Based Encryption
Security Proofs Boneh-Franklin’s Identity-Based Encryption
2010/3/16
Boneh and Franklin constructed the first practical
Identity-Based Encryption (IBE) scheme in 2001. They also
defined a formal security model for IBE and proved their
scheme (BF-IBE) to be secure in...
