A Practical Forward-Secure DualRing

2023
Ring signature allows a signer to generate a signature on behalf of a set of public keys, while a verifier can verify the signature without identifying who the actual signer is. In Crypto 2021, Yuen et al. proposed a new type of ring signature scheme called DualRing. However, it lacks forward security.

Forward Security with Crash Recovery for Secure Logs

ACM Transactions on Privacy and Security, 2023
Logging is a key mechanism in the security of computer systems. Beyond supporting important forward security properties, it is critical that logging withstands both failures and intentional tampering to prevent subtle attacks leaving the system in an inconsistent state with inconclusive evidence. We propose new techniques combining forward

Moving forward? [digital security]

IEEE Security & Privacy, 2003
The US government and the European Commission recently made major Cyber security policy pronouncements in their attempts to achieve the right mix. The US strategy states that the newly created Department of Homeland Security will become a federal center of excellence for Cyber security, providing a focal point for federal outreach to state and local ...

Forward-Secure Multi-signatures

2008
In many applications a document needs to be signed by more than one signer. When a signature depends on more than one signer we call it a multi-signature. Further, ordinary digital signatures have an inherent weakness: if the secret key is leaked, then all signatures, even the ones generated before the leak, are no longer trustworthy.

Forward-Secure Certificate-Based Encryption

2009 Fifth International Conference on Information Assurance and Security, 2009
Certificate-based encryption (CBE) is a new paradigm which overcomes the shortcomings of traditional public-key encryption (PKE) and identity based encryption (IBE). CBE provides an efficient implicit certificate mechanism to eliminate third-party queries for the certificate status and to simplify the certificate revocation problem in traditional PKI ...
