Threshold ring signature without random oracles
Proceedings of the 6th ACM Symposium on Information, Computer and Communications Security, 2011 In this paper, we present the notion and construction of threshold ring signature without random oracles. This is the first scheme in the literature that is proven secure in the standard model. Our scheme extends the Shacham-Waters signature from PKC 2007 in a non-trivial way.

Threshold ring signature scheme based on the curve [PDF]
IEEE International Symposium on Information Theory, 2003. Proceedings., 2003 Rivest, Shamir, and Tauman (2001) have proposed a ring signature scheme, which is signer-ambiguous and setup-free. Bresson, Stern, and Szydlo (2002) have extended it to a threshold ring signature scheme. In this paper, we propose another type of the threshold ring signature scheme. While the sequence of signatures of the previous ring signature schemes

How does star formation proceed in the circumnuclear starburst ring of NGC 6951?
, 2013 Gas inflowing along stellar bars is often stalled at the location of circumnuclear rings, that form an effective reservoir for massive star formation and thus shape the central regions of galaxies. However, how exactly star formation is proceeding within

On the existence of $F$-thresholds and related limits
, 2017 The $F$-thresholds are important numerical invariants in prime characteristic, whose existence had been established only under certain assumptions. We show the existence of $F$-thresholds in full generality.

Threshold ring signature: generic construction and logarithmic size instantiation
CybersecurityA ring signature is a variant of normal digital signature and protects the privacy of a specific signer in the sense that a ring signature can be verified, but the signer’s identity can only be traced to a limited set. The concept was further enhanced to

A Lattice-Based Threshold Ring Signature Scheme [PDF]
, 2010 In this article, we propose a new lattice-based threshold ring signature scheme, modifying Aguilar's code-based solution to use the short integer solution (SIS) problem as security assumption, instead of the syndrome decoding (SD) problem. By applying the CLRS identification scheme, we are also able to have a performance gain as result of the reduction

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
