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.

Complex Regimes: How overlapping and inconsistent regulation constrains the adoption of cloud services [PDF]
, 2023 Inconsistent and unclear regulatory regimes for cloud-service providers could challenge essential cyber security protections for Australians at a time of escalating cyber incidents and geopolitical risk.

5G Handover : When Forward Security Breaks [PDF]
, 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.

A New Digital Signature Primitive and Its Application in Blockchain
IEEE Access, 2023 In this paper, we propose a new digital signature primitive, called expander signature, and discuss its application in blockchain. The most promising advantage of expander signature is that a signer can generate all signatures at once using a powerful ...

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

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–

Research on Quantum-Attack-Resistant Strong Forward-Secure Signature Schemes
Entropy, 2023 The security of digital signatures depends significantly on the signature key. Therefore, to reduce the impact of leaked keys upon existing signatures and subsequent ones, a digital signature scheme with strong forward security could be an effective ...

A Note on an Improved Self-Healing Group Key Distribution Scheme
Sensors, 2015 In 2014, Chen et al. proposed a one-way hash self-healing group key distribution scheme for resource-constrained wireless networks in the journal of Sensors (14(14):24358-24380, doi: 10.3390/ s141224358).

Towards Forward Security Properties for PEKS and IBE [PDF]
, 2015 peer reviewedIn cryptography, forward secrecy is a well-known property for key agreement protocols. It ensures that a session key will remain private even if one of the long-term secret keys is compromised in the future.

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.
