A Forward-Secure Digital Signature Scheme [PDF]
, 1999 We describe a digital signature scheme in which the public key is fixed but the secret signing key is updated at regular intervals so as to provide a forward security property: compromise of the current secret key does not enable an adversary to forge signatures pertaining to the past.

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 ...

5G Handover: When Forward Security Breaks
Proceedings of the 20th International Conference on Security and Cryptography, 2023 5G mobility management is dependent on a couple of complex protocols for managing handovers, based on the available network interfaces (such as Xn and N2). In our work, we focus on the 5G Xn handover procedure, as defined by the 3GPP standard. In Xn handovers, the source base station hands the user equipment (UE) over to a target base station through ...

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 ...

Secure Distributed Computation of the Square Root and Applications [PDF]
, 2012 The square root is an important mathematical primitive whose secure, efficient, distributed computation has so far not been possible. We present a solution to this problem based on Goldschmidt's algorithm.

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.

Lattice Blind Signatures with Forward Security
, 2020 Blind signatures play an important role in both electronic cash and electronic voting systems. Blind signatures should be secure against various attacks (such as signature forgeries). The work puts a special attention to secret key exposure attacks, which totally break digital signatures.

A Forward-Secure Digital Signature Based on Elliptic Curve
Dianxin kexue, 2015 The forward-secure digital signature is an important digital signature scheme.It requires that even if the attackers have already been given a signature key by invading a system in t time，it still can’t forge signatures before time t.In other words，the ...

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