, 2001 Forward security has been propose as a method to minimized the consequences of key exposure. In this paper we analyze this method and consider vulnerability, which is due to the fact that the exposure may not have been detected. All forward secure crytosystems proposed so far are vulnerable during the period between key exposure and it detection.

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 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.

The ForwardDiffSig scheme for multicast authentication [PDF]
, 2010 This paper describes ForwardDiffSig, an efficient scheme for multicast authentication with forward security. This scheme provides source authentication, data integrity, and non-repudiation since it is based on the use of asymmetric cryptography.

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

Ouroboros Praos: An Adaptively-Secure, Semi-synchronous Proof-of-Stake Blockchain [PDF]
, 2018 We present “Ouroboros Praos”, a proof-of-stake blockchain protocol that, for the first time, provides security against fully-adaptive corruption in the semi-synchronous setting: Specifically, the adversary can corrupt any participant of a dynamically ...

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 ...

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 ...
