Lattice-based group signatures with forward security for anonymous authentication [PDF]
Heliyon, 2023 Group signatures allow users to sign messages on behalf of a group without revealing authority is capable of identifying the user who generated it. However, the exposure of the user's signing key will severely damage the group signature scheme.

IFIP Advances in Information and Communication Technology, 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.

DS-CKDSE: A Dual-Server Conjunctive Keyword Dynamic Searchable Encryption with Forward and Backward Security [PDF]
EntropyDynamic Searchable Encryption (DSE) is essential for enabling confidential search operations over encrypted data in cloud computing. However, all existing single-server DSE schemes are vulnerable to Keyword Pair Result Pattern (KPRP) leakage and fail to ...

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.

A Modern View on Forward Security [PDF]
The Computer Journal, 2020 Abstract Forward security ensures that compromise of entities today does not impact the security of cryptographic primitives employed in the past. Such a form of security is regarded as increasingly important in the modern world due to the existence of adversaries with mass storage capabilities and powerful infiltration abilities ...

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 ...

Formal Verification of Secure Forwarding Protocols [PDF]
2021 IEEE 34th Computer Security Foundations Symposium (CSF), 2021 Today’s Internet is built on decades-old networking protocols that lack scalability, reliability, and security. In response, the networking community has developed path-aware Internet architectures that solve these issues while simultaneously empowering end hosts. In these architectures, autonomous systems construct authenticated forwarding paths based
