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.

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 ...

Forward secure proxy signature scheme
Tongxin xuebao, 2005 A forward secure proxy signature scheme was proposed combining the concept of forward security with proxy signature. This means even if an adversary has gotten the current proxy signers’ key.

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 ...

Towards Forward Secure Internet Traffic [PDF]
, 2019 Forward Secrecy (FS) is a security property in key-exchange algorithms which guarantees that a compromise in the secrecy of a long-term private-key does not compromise the secrecy of past session keys. With a growing awareness of long-term mass surveillance programs by governments and others, FS has become widely regarded as a highly desirable property.

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 ...

, 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.
