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 Threshold Signature Schemes
2001We 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 searchable symmetric encryption
2017 12th International Conference for Internet Technology and Secured Transactions (ICITST), 2017Data 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 Linkable Ring Signatures
2018We 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.

Forward-Security Under Continual Leakage
2018Current signature and encryption schemes secure against continual leakage fail completely if the key in any time period is fully exposed. We suggest forward security as a second line of defense, so that in the event of full exposure of the current secret key, at least uses of keys prior to this remain secure, a big benefit in practice.

Forward Secure Attribute-Based Signatures
2012Attribute-Based Signatures (ABS) is a versatile primitive which allows an entity to sign a message with fine-grained control over identifying information. A valid ABS only attests to the fact that "A single user, whose attributes satisfy the predicate, has endorsed the message".

Efficient Forward-Secure Threshold Signatures
2020Forward-secure threshold signatures are useful to mitigate the damage of secret key exposure. Constructions based on bilinear pairings are particularly interesting because they achieve shorter signatures than RSA-based constructions.

Adaptively Secure Forward-Secure Non-interactive Threshold Cryptosystems
2012Threshold cryptography aims at enhancing the availability and security of decryption and signature schemes by splitting private keys into several (say n) shares (typically, each of size comparable to the original secret key). In these schemes, a quorum of at least (d≤n) servers needs to act upon a message to produce the result (decrypted value or ...

Security analysis of a flexible forward-secure signature scheme
IET 2nd International Conference on Wireless, Mobile and Multimedia Networks (ICWMMN 2008), 2008Huang and Chang proposed a flexible forward-secure signature scheme in International Journal of Computer Science and Network Security in 2006. In this paper, we give the security analysis of this scheme and point out this scheme doesn't satisfy the forward security.
