A fully dynamic forward-secure group signature from lattice

open access: yesCybersecurity, 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

open access: yesIEEE 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 Edge Authentication for Graphs

open access: yesThe Computer Journal, 2021
AbstractThe edge authentication of graphs has been studied in the literature because graphs are one of the most widely used data organization structures. The majority of such schemes cannot be used to authenticate general directed graphs (GDGs); other schemes cannot be used for addressing either the issue of dynamic update or the issue of information ...

Binary Tree Based Forward Secure Signature Scheme in the Random Oracle Model [PDF]

open access: yesInternational 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 ring signature without random oracles [PDF]

open access: yes, 2011
In this paper, we propose a forward secure ring signature scheme without random oracles. With forward security, if a secret key of a corresponding ring member is exposed, all previously signed signatures containing this member remain valid.

Forward-Secure Linkable Ring Signatures from Bilinear Maps

open access: yesCryptography, 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 ...

Toward Forward Secure SSE Supporting Conjunctive Keyword Search

open access: yesIEEE 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.

UC and EUC Weak Bit-Commitments Using Seal-Once Tamper-Evidence [PDF]

open access: yesScientific Annals of Computer Science, 2013
Based on tamper-evident devices, i.e., a type of distinguishable, sealed envelopes, we put forward weak bit-commitment protocols which are UC-secure. These commitments are weak in that it is legitimate that a party could cheat.
