Forward-Secure Threshold Signature Schemes
, 2001 We construct forward-secure threshold signature schemes. These schemes have the following property: even if more than the threshold number of players are compromised, it is not possible to forge signatures relating to the past. This property is achieved while keeping the public key fix ed and updating the secret keys at regular intervals.

Forward-secure signatures with untrusted update
Proceedings of the 13th ACM conference on Computer and communications security, 2006In most forward-secure signature constructions, a program that updates a user's private signing key must have full access to the private key. Unfortunately, these schemes are incompatible with several security architectures including Gnu Privacy Guard (GPG) and S/MIME, where the private key is encrypted under a user password as a "second factor" of ...

Forward-Secure Certificate-Based Encryption
2009 Fifth International Conference on Information Assurance and Security, 2009Certificate-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 ...

Forward-Secure Multi-signatures
2008In 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 Delay-Tolerant Networking
Proceedings of the 12th Workshop on Challenged Networks, 2017Delay-Tolerant Networks exhibit highly asynchronous connections often routed over many mobile hops before reaching its intended destination. The Bundle Security Protocol has been standardized providing properties such as authenticity, integrity, and confidentiality of bundles using traditional Public-Key Cryptography.

Forward-Secure Multi-Signatures. [PDF]
IACR Cryptol. ePrint Arch., 2019 Multi-signatures allow a group of signers to jointly sign a message in a compact and efficiently verifiable signature, ideally independent of the number of signers in the group.
