Dynamic Searchable Symmetric Encryption with Forward and Stronger Backward Privacy
Dynamic Searchable Symmetric Encryption Forward Privacy Backward Privacy
font style='font-size:12px;'>
2019/9/19
Dynamic Searchable Symmetric Encryption (DSSE) enables a client to perform updates and searches on encrypted data which makes it very useful in practice. To protect DSSE from the leakage of updates (l...
Balance : Dynamic Adjustment of Cryptocurrency Deposits
cryptocurrency deposit security
font style='font-size:12px;'>
2019/6/10
In cryptoeconomic protocols, financial deposits are fundamental to their security. Protocol designers and their agents face a trade-off when choosing the deposit size. While substantial deposits might...
Utreexo: A dynamic hash-based accumulator optimized for the Bitcoin UTXO set
accumulators bitcoin merkle proofs
font style='font-size:12px;'>
2019/6/4
In the Bitcoin consensus network, all nodes come to agreement on the set of Unspent Transaction Outputs (The “UTXO” set). The size of this shared state is a scalability constraint for the network, as ...
Unbounded Dynamic Predicate Compositions in Attribute-Based Encryption
attribute-based encryption predicate encryption nested policy
font style='font-size:12px;'>
2019/3/4
We present several transformations that combine a set of attribute-based encryption (ABE) schemes for simpler predicates into a new ABE scheme for more expressive composed predicates. Previous proposa...
CHURP: Dynamic-Committee Proactive Secret Sharing
secret sharing threshold cryptography blockchains
font style='font-size:12px;'>
2019/1/9
We introduce CHURP (CHUrn-Robust Proactive secret sharing). CHURP enables secure secret-sharing in dynamic settings, where the committee of nodes storing a secret changes over time. Designed for block...
Observations on the Dynamic Cube Attack of 855-Round TRIVIUM from Crypto'18
Dynamic Cube attack Division Property MILP
font style='font-size:12px;'>
2018/11/6
Recently, another kind of dynamic cube attack is proposed by Fu et al. With some key guesses and a transformation in the output bit, they claim that, when the key guesses are correct, the degree of th...
Membership Privacy for Fully Dynamic Group Signatures
SFPK SPSEQ
font style='font-size:12px;'>
2018/7/9
Group signatures present a trade-off between the traditional goals of digital signatures and the signer's desire for privacy, allowing for the creation of unforgeable signatures in the name of a group...
Dynamic Searchable Symmetric Encryption Schemes Supporting Range Queries with Forward (and Backward) Security
Dynamic searchable symmetric encryption forward security backward security
font style='font-size:12px;'>
2018/6/27
Dynamic searchable symmetric encryption (DSSE) is a useful cryptographic tool in the encrypted cloud storage. However, it has been reported that DSSE usually suffers from the file-injection attacks an...
Composable Proof-of-Stake Blockchains with Dynamic Availability
Blockchain Consensus
font style='font-size:12px;'>
2018/5/2
Proof-of-stake-based (in short, PoS-based) blockchains aim to overcome scalability, effi- ciency, and composability limitations of the proof-of-work paradigm, which underlies the security of several m...
Efficient and Constant-Rounds Secure Comparison through Dynamic Groups and Asymmetric Computations
cryptographic protocols secure comparison
font style='font-size:12px;'>
2018/3/6
Within recent years, secure comparison protocols have been proposed using binary decomposition and properties of algebraic fields. These have been repeatedly optimized and increased in efficiency, but...
