A New Post-Quantum Blind Signature From Lattice Assumptions

open access: yesIEEE Access, 2018
At present, several post-quantum cryptosystems have been proposed, and lattice-based cryptography is the main candidate. Especially in the direction of digital signatures, there are now many practical lattice-based signature schemes. However, there exist

Blinding for Unanticipated Signatures [PDF]

open access: yes, 2010
Previously known blind signature systems require an amount of computation at least proportional to the number of signature types, and also that the number of such types be fixed in advance. These requirements are not practical in some applications. Here, a new blind signature technique is introduced that allows an unlimited number of signature types ...

A Blind Digital Signature Protocol over NTRU [PDF]

open access: yesE3S Web of Conferences, 2022
Actually, the NIST post-quantum cryptosystem standardization competition reached its third round with seven finalist candidates. And NIST invites the cryptographic community to analyzing the selected candidates. In this context, we contribute by creating

Lattice-Based Blind Signatures [PDF]

open access: yes, 2010
Motivated by the need to have secure blind signatures even in the presence of quantum computers, we present two efficient blind signature schemes based on hard worst-case lattice problems. Both schemes are provably secure in the random oracle model and unconditionally blind. The first scheme is based on preimage samplable functions that were introduced

Blind electronic signature on elliptic curves method: conditions and requirements

open access: yesНаука. Инновации. Технологии, 2022
The work is devoted to consideration the blind electronic signature method based on algorithm, described in DSTU ISO/IEC 14888-3:2014 (EC DSA). The blind electronic signatures protocol mathematical model based on a standard electronic signature algorithm

Partially Blind Proxy Re-Signature Scheme Without Bilinear Pairing [PDF]

open access: yesJisuanji gongcheng, 2020
To address complex bilinear pairing operations and certificate management problems of existing blind proxy re-signature schemes,by using WANG’s scheme for reference,this paper proposes a partially blind proxy re-signature scheme without bilinear pairing ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Circulating tumor cell viability during and after radiotherapy mirrors treatment response in cancer patients

open access: yesMolecular Oncology, EarlyView.
Radiotherapy (RT) response depends on the DNA repair capacity of tumor and host cells. We show that circulating tumor cell (CTC) counts and apoptosis rates before and after RT predict treatment response and outcome, which can be accessed via easily accessible liquid biopsy approaches. Created in BioRender. Wikman, H.

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis

open access: yesFEBS Open Bio, EarlyView.
Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.

Partially blind proxy re-signature scheme with proven security

open access: yesTongxin xuebao, 2018
In order to solve the problem of anonymity and controllability of blind proxy re-signature,the concept of partially blind proxy re-signature was introduced by using the idea of partially blind signature.Furthermore,the security definition of partially ...
