Lattice-based group signatures with forward security for anonymous authentication [PDF]
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.

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.

Secure Computation-and-Forward With Linear Codes [PDF]
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]
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 ...

A remote sensing encrypted data search method based on a novel double-chain
Remote sensing is considered to be a key technology for the development of smart cities. By analysing the data obtained by remote sensing, it is effective to manage and develop smart cities.

Protocol to enhance the security of Early data in TLS 1.3
The new 0-RTT Internet key exchange was drawn on the TLS 1.3 session resumption phase,the rFSOPKE protocol was constructed,and the Early data encryption and transmission process were improved.The rFSOPKE protocol can protect the forward security of Early

A Note on an Improved Self-Healing Group Key Distribution Scheme
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).

A New Digital Signature Primitive and Its Application in Blockchain
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
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
