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.

Forward Secure Conjunctive-Keyword Searchable Encryption
IEEE Access, 2019 Searchable symmetric encryption (SSE) has been applied in constructing secure cloud storage for its simplicity, high-efficiency, and practicality. Recent works show that forward privacy has become a fundamental property required for SSE, and several ...

A fully dynamic forward-secure group signature from lattice
Cybersecurity, 2022 A forward-secure group signature (FSGS) ensures the unforgeability of signatures in the past time period despite signing secret key is leaked in the current time period.

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

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–

Binary Tree Based Forward Secure Signature Scheme in the Random Oracle Model [PDF]
International Journal of Electronics and Telecommunications, 2021 In this paper we construct and consider a new group-based digital signature scheme with evolving secret key, which is built using a bilinear map. This map is an asymmetric pairing of Type 3, and although, for the reason of this paper, it is treated in a ...

Forward-Secure Linkable Ring Signatures from Bilinear Maps
Cryptography, 2018 We present the first linkable ring signature scheme with both unconditional anonymity and forward-secure key update: a powerful tool which has direct applications in elegantly addressing a number of simultaneous constraints in remote electronic voting ...
