A New Digital Signature Primitive and Its Application in Blockchain
IEEE Access, 2023 In this paper, we propose a new digital signature primitive, called expander signature, and discuss its application in blockchain. The most promising advantage of expander signature is that a signer can generate all signatures at once using a powerful ...

Forward-Secure Multi-User Aggregate Signatures Based on zk-SNARKs
IEEE Access, 2021 As a solution to mitigate the key exposure problems in the digital signature, the forward security has been proposed. The forward security guarantees the integrity of the messages generated in the past despite leaks of a current time period secret key by

Research on Quantum-Attack-Resistant Strong Forward-Secure Signature Schemes
Entropy, 2023 The security of digital signatures depends significantly on the signature key. Therefore, to reduce the impact of leaked keys upon existing signatures and subsequent ones, a digital signature scheme with strong forward security could be an effective ...

Forward-Secure Distributed Encryption [PDF]
, 2014 Distributed encryption is a cryptographic primitive that implements revocable privacy. The primitive allows a recipient of a message to decrypt it only if enough senders encrypted that same message. We present a new distributed encryption scheme that is simpler than the previous solution by Hoepman and Galindo–in particular it does not rely on pairings–

Forward-Secure Hierarchical Predicate Encryption [PDF]
The Computer Journal, 2013 Secrecy of decryption keys is an important pre-requisite for security of any encryption scheme and compromised private keys must be immediately replaced. \emph{Forward Security (FS)}, introduced to Public Key Encryption (PKE) by Canetti, Halevi, and Katz (Eurocrypt 2003), reduces damage from compromised keys by guaranteeing confidentiality of messages ...

Secure Computation-and-Forward With Linear Codes [PDF]
IEEE Journal on Selected Areas in Information Theory, 2021 We discuss secure transmission via an untrusted relay when we have a multiple access phase from two nodes to the relay and broadcast phase from the relay to the two nodes. To realize the security, we construct a code that securely transmits the modulo sum of the messages of two nodes via a multiple access channel.

Toward Forward Secure SSE Supporting Conjunctive Keyword Search
IEEE Access, 2019 The primitive of Searchable Symmetric Encryption (SSE) allows a server to perform search directly over encrypted documents. Recently, forward secure SSE (FSSE) has attracted significant attention due to its secure property for document update.

IEEE Access, 2020 In the Vehicle-to-Grid (V2G) network, the electric vehicles (EVs) need to report their respective information, such as vehicle identity, battery capacity, battery state of charge (SoC), current location, and driving direction, to the power grid through ...
