Forward-Security in Private-Key Cryptography [PDF]

, 2003
This paper provides a comprehensive treatment of forwardsecurity in the context of shared-key based cryptographic primitives, as a practical means to mitigate the damage caused by key-exposure. We provide definitions of security, practical proven-secure constructions, and applications for the main primitives in this area.

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-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 ...

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 Delay-Tolerant Networking

Proceedings of the 12th Workshop on Challenged Networks, 2017
Delay-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 searchable symmetric encryption

2017 12th International Conference for Internet Technology and Secured Transactions (ICITST), 2017
Data outsourcing to third party clouds poses numerous data security threats. Access by unauthorized users is one of the security threat to the outsourced data. Unauthorized access can be avoided by encrypting the data before outsourcing. However, encrypting data before outsourcing renders it unsearchable to the data owner. Searchable encryption schemes

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 Linkable Ring Signatures

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.
