Leakage-resilient identity-based cryptography from minimal assumptions
Identity-based hash proof system (IB-HPS), a variant of hash proof system (HPS) in the identity-based setting, is a useful building block in cryptography. In EUROCRYPT 2010 (Alwen et al in Advances in cryptolo...

Novel generic construction of leakage-resilient PKE scheme with CCA security
Leakage of private state information (e.g. the secret keys) through various leakage attacks (e.g. side channel attacks, cold-boot attacks, etc) has become a serious threat to the security of computer systems i...

Strongly leakage resilient authenticated key exchange, revisited
Authenticated Key Exchange (AKE) protocols allow two (or multiple) parties to authenticate each other and agree on a common secret key, which is essential for establishing a secure communication channel over a...

Continuous leakage-resilient identity-based encryption with leakage amplification
In modern computer systems, leakage of private information may cause catastrophic consequences, especially those are related to the secret keys in cryptographic mechanisms. Therefore, it has been widely accept...

Threshold privacy-preserving cloud auditing with multiple uploaders
Data integrity is a critical security issue in cloud storage. The data integrity checking schemes by a third-party auditor (TPA) have attracted a lot of attention. Sharing data among multiple users (uploaders)...

Provably Secure Proactive Secret Sharing Without the Adjacent Assumption
In secret sharing (SS), the secret is shared among a number of parties so that only a quorum of these parties can recover the secret, but a smaller set of parties cannot learn any information about the secret....

Ciphertext-policy attribute-based encryption supporting access policy update and its extension with preserved attributes
Attribute-based encryption (ABE) allows one-to-many encryption with static access control. In many occasions, the access control policy must be updated, but the original encryptor might be unavailable to re-en...

Flexible ciphertext-policy attribute-based encryption supporting AND-gate and threshold with short ciphertexts
Ciphertext-policy attribute-based encryption (CP-ABE) is a very promising cryptographic primitive that allows a data owner to encrypt messages and manage access policies themselves. Most of the existing CP-ABE...

Efficient Attribute-Based Encryption with Blackbox Traceability
Traitor tracing scheme can be used to identify a decryption key is illegally used in public-key encryption. In CCS’13, Liu et al. proposed an attribute-based traitor tracing (ABTT) scheme with blackbox traceab...

An Efficient and Provably Secure Private Polynomial Evaluation Scheme
Private Polynomial Evaluation (PPE) allows the service provider to outsource the computation of a polynomial to some third party (e.g. the Cloud) in a verifiable way. And meanwhile, the polynomial remains hidd...

Efficient identity-based online/offline encryption and signcryption with short ciphertext
The technique of online/offline is regarded as a promising approach to speed up the computation of encryption, because the most part of computation, such as pairing over points on elliptic curve and exponentia...

Group-Based Source-Destination Verifiable Encryption with Blacklist Checking
We consider user conditional privacy preservation in the context of public key encryption. Unlike the full privacy preservation, our conditional one ensures that the message sender’s as well as the intended re...

Achieving IND-CCA Security for Functional Encryption for Inner Products
Functional encryption allows the authorised parties to reveal partial information of the plaintext hidden in a ciphertext while in conventional encryption decryption is all-or-nothing. Focusing on the function...
