A New Post-Quantum Blind Signature From Lattice Assumptions
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]
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]
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]
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
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]
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 ...

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.

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
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
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 ...
