CCA-Secure Leakage-Resilient Identity-Based Key-Encapsulation from Simple (not $\mathtt{q}$-type) Assumptions
public-key cryptography leakage-resilient identity-based encryption
font style='font-size:12px;'>
2019/8/30
In this paper, we propose a new leakage-resilient identity-based encryption (IBE) scheme that is secure against chosen-ciphertext attacks (CCA) in the bounded memory leakage model. It is the first CCA...
Identity-Based Key Aggregate Cryptosystem from Multilinear Maps
Key-Aggregate Cryptosystem Identity-based Online Data Sharing
font style='font-size:12px;'>
2016/7/14
The key-aggregate cryptosystem (KAC) proposed by Chu et al. in 2014 offers a solution
to the flexible access delegation problem in shared data environments such as the cloud.
KAC allows a data owner...
An Efficient Multiple PKG Compatible Identity Based Key Agreement for Vehicular Networks
Provable Security Random Oracle Model eCK model
font style='font-size:12px;'>
2015/12/22
In this paper we propose an efficient single-round, two-party
identity based authenticated key agreement protocol in the setting of
multiple Private Key Generators (PKGs). One of the major advantage...
Identity-Based Key-Encapsulation Mechanism from Multilinear Maps
Key-Encapsulation Multilinear Maps
font style='font-size:12px;'>
2014/3/5
We construct an Identity-Based Key Encapsulation Mechanism (IB-KEM) in a generic "leveled" multilinear map setting and prove its security under multilinear decisional Diffie-Hellmanin assumption in th...

Utilizing postponed ephemeral and pseudo-static keys in tripartite and identity-based key agreement protocols
Postponed ephemeral keys pseudo-static keys tripartite key agreement
font style='font-size:12px;'>
2009/9/2
We propose an new one-round implicitly authenticated three-party protocol that ex-
tends Joux's protocol as well as a two-party identity-based protocol. Our protocols have a single
communication rou...
Chosen-Ciphertext Secure Fuzzy Identity-Based Key Encapsulation without ROM
chosen-ciphertext security hybrid encryption fuzzy identity based encryption
font style='font-size:12px;'>
2009/6/3
We use hybrid encryption with Fuzzy Identity-Based Encryption (Fuzzy-IBE) schemes, and present the first and efficient fuzzy identity-based key encapsulation mechanism (Fuzzy-IB-KEM) schemes which are...
Security Proof for the Improved Ryu{Yoon{Yoo Identity-Based Key Agreement Protocol
Key agreement protocols Reection attack Provable security
font style='font-size:12px;'>
2009/6/2
Key agreement protocols are essential for secure communications in open
and distributed environments. The protocol design is, however, extremely error-prone
as evidenced by the iterative process of ...

font style='font-size:12px;'>
2009/4/2
In identity-based (ID-based) cryptosystems, a local registration authority
(LRA) is responsible for authentication of users while the key generation
center (KGC) is responsible for computing and sen...

Enhancing CK-Model Key Compromise Impersonation Resilience Identity-based Key
font style='font-size:12px;'>
2009/3/19
In 2001, Canetti and Krawczyk proposed a security model (CKmodel)
for authentication protocols. They also gave an indistinguishabilitybased
definition for key exchange protocols. Since then the mode...

2009/3/6
In most of the existing identity-based key agreement schemes,
it is usually assumed that either the communicated parties know each
other's identifier before the protocol starts or their identifiers ...

We introduce the concept of identity based key encapsulation
to multiple parties (mID-KEM), and define a security model for it. This
concept is the identity based analogue of public key KEM to mult...
