Cryptanalysis of Nonrepudiable Threshold Proxy Signature Schemes with Known Signers [PDF]
, 2009 [[abstract]]In 2000, Hwang et al. proposed a nonrepudiable threshold proxy signature scheme to improve Sun’s scheme. In this paper, a new attack is proposed to show that, both in Hwang et al.’s and Sun’s schemes, the threshold proxy signatures can be ...

Review and Analysis of Cryptographic Schemes Implementing Threshold Signature
Безопасность информационных технологий, 2015 This work is devoted to the study of threshold signature schemes. The systematization of the threshold signature schemes was done, cryptographic constructions based on interpolation Lagrange polynomial, ellipt ic curves and bilinear pairings were ...

Molecular Oncology, EarlyView.The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.

Security Analysis of a Threshold Proxy Signature Scheme Using Self certified Public Keys
工程科学与技术, 2008 :Xue and Cao proposed a threshold proxy signature scheme using self certified public keys, but this scheme was insecure. An attack against this scheme was proposed. By this attack, an adversary could forge an illegal proxy signature.

Engineering IL‐4 resistant proinflammatory human myeloid cells for cancer immunotherapy
Molecular Oncology, EarlyView.We developed a scalable workflow to generate proinflammatory human myeloid cells. CRISPR/Cas9‐edited CD34+ hematopoietic stem and progenitor cells were expanded and differentiated with M‐CSF. Deletion of STAT6 or STAT6/NFKB1 enhanced macrophage proinflammatory gene expression and cytokine secretion in the presence of IL‐4 while maintaining antibody ...

A Multi-policy Threshold Signature Scheme with Traceable Participant Cosigners
, 2009 [[abstract]]In a (t, n) threshold scheme, the secret can be reconstructed by the cooperation of t or more users. With this basic concept, Lee devised a threshold signature scheme with multiple signing policies in 2001.

Tumour‐proximal deep serum proteomics identifies biomarkers associated with ovarian cancer
Molecular Oncology, EarlyView.New biomarkers are needed for early ovarian cancer detection. Ovarian (tumour‐proximal) and peripheral vein serum from healthy women and patients with benign or malignant tumours underwent nanoparticle‐enriched deep proteomics. Ovarian serum yielded more protein identifications and revealed tumour‐reflective signatures.

A Threshold Signature Scheme Withstanding the Conspiracy Attack
, 2012 [[abstract]]A threshold signature, first proposed by Desmedt and Frankel, allows or more members of the group cooperate to generate a signature on behalf of the group while providing the anonymity of the signers.

Progress of the international H-mode power threshold database activity
, 2002 The International Global H-mode Threshold Database has been revised and cleaned from inadequate data for some tokamaks. This significantly reduces the scatter for the corresponding datasets.
