Attribute-based alterable threshold ring signature scheme with conspiracy attack immunity
Attribute-based cryptography is a generalization and development of the identity-based cryptography,which extends the identity to a set of attributes.In the attribute-based cryptosystem,different members with the same attributes can form a signature ring

Communicating Unforgiveness: How Do Victims Communicate Their Unforgiveness to Their Offenders?
When faced with interpersonal transgressions, some victims maintain unforgiveness towards their offenders. Researchers have identified emotions and cognitions experienced by victims who maintain unforgiveness, but the literature has yet to move beyond investigating the intrapersonal experience of unforgiveness.

On the Non-repudiation of Isogeny Based Signature Scheme
Part 3: CryptographyInternational audienceFor a digital signature scheme, unforgeability and non-repudiation are two main security requirements. In 2017, Galbraith, Petit and Silva presented GPS signature, an efficient isogeny based signature with a ...

Short Generic Transformation to Strongly Unforgeable Signature in the Standard Model
Standard signature schemes are usually devised to merely achieve existential unforgeability, i.e., to prevent forgeries on new messages not previously signed. Unfortunately, existential unforgeability is not suitable for several applications, since a new

On the unforgeability of the Chaum - Pedersen blind signature scheme
The paper is devoted to the analysis of the unforgeability property of the Chaum - Pedersen blind signature scheme in case an adversary is able to initiate parallel sessions of the signature generation protocol. It is shown that the scheme does not ensure strong unforgeability, i.e., it allows to create the forgeries for “old” messages that were ...

Proxying Is Enough: Security of Proxying in TLS Oracles and AEAD Context Unforgeability [PDF]
TLS allows a client to securely obtain data from a server, but does not allow the client to offer the data provenance to an external node. TLS oracle protocols are used to solve the problem.

Unforgeable Watermarks for Language Models via Robust Signatures
Language models now routinely produce text that is difficult to distinguish from human writing, raising the need for robust tools to verify content provenance. Watermarking has emerged as a promising countermeasure, with existing work largely focused on model quality preservation and robust detection. However, current schemes provide limited protection

On the Improvement of the Security of Signcryption Scheme
[[abstract]]Zheng proposed two new authenticated encryption schemes, called signcryption, in 1997. But the studies of Petersen and Michels showed that these schemes have the problem “to achieve non-repudiation is to lose confidentiality”. They outlined a

Comment on “An efficient identity-based signature scheme with provable security”
In this comment paper, we reveal a security issue in an efficient identity-based signature (IBS) scheme that has been proven secure in the standard model.

homomorphic linear authentication schemes for proofs of retrievability
In a proof of retrievability (POR) system, interactive POR protocols are executed between a storage server and clients, so that clients can be convinced that their data is available at the storage server, ready to be retrieved when needed.
