Spatial Encryption Revisited: From Delegatable Multiple Inner Product Encryption and Moret, we then successfully instantiate a concrete DMIPE construction relying on the hardness of the decisional learning with errors problem. In turn, the DMIPE design implies a more compact lattice-based SE in terms of sizes compared with SEs converted from HIPE (e.g., Xagawa’s HIPE at PKC 2013) using

An Efficient Query Recovery Attack Against a Graph Encryption Schemeutput is guaranteed to contain the correct query. For a graph on . vertices, our attack runs in time . and matches the time complexity of the GKT scheme’s setup. We evaluate the attack’s performance using the real world datasets used in the original paper and show that as many as 21.9% of the querie

A Blockchain-Based Long-Term Time-Stamping Schemes authority, decentralized Blockchain-based Time-Stamping (BTS) services have been proposed. In these services, a hash digest of users’ data is written into a blockchain transaction. The security of such services relies on the security of hash functions used to hash the data, and of the cryptographi

Zero-History Confidential Chains with Zero-Knowledge Contracts: A New Normal for Decentralized Ledgeomputational fees, and impractical overheads for syncing. The origin of these problems is . that comes with the architecture of “append-only” blockchains, e.g., Bitcoin, Ethereum, Hyperledger, etc. Zero-history blockchains like Origami address the root of these problems by removing the history.
