Multi-Authority Secret-Ballot Elections with Linear Work [PDF]
, 1996 We present new cryptographic protocols for multi-authority secret ballot elections that guarantee privacy, robustness, and univer- sal verifiability. Application of some novel techniques, in particular the construction of witness hiding/indistinguishable protocols from Cramer, Damgård and Schoenmakers, and the verifiable secret sharing scheme of ...

A multi-candidate electronic voting scheme with unlimited participants
, 2017 In this paper a new multi-candidate electronic voting scheme is constructed with unlimited participants. The main idea is to express a ballot to allow voting for up to k out of the m candidates and unlimited participants. The purpose of vote is to select

Systematizing Decentralization and Privacy: Lessons from 15 Years of Research and Deployments [PDF]
, 2017 Decentralized systems are a subset of distributed systems where multiple authorities control different components and no authority is fully trusted by all. This implies that any component in a decentralized system is potentially adversarial.

IEEE Access, 2019 In 2018, Yang et al. proposed a decentralized multi-authority attribute-based encryption scheme for cloud computing applications and proved its security using the dual system encryption technique. In this comment, we show that Yang et al.’s scheme

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Families of children with cancer experience significant financial strain, even with universal healthcare. Indirect costs, such as productivity losses and non‐medical expenses, are rarely included in economic evaluations, and little is known about how effectively financial aid programmes alleviate this burden. Childhood brain tumours

Multi-Authority Non-Monotonic KP-ABE With Cryptographic Reverse Firewall
IEEE Access, 2019 The revelations of Snowden show that hardware and software of devices may corrupt users' machine to compromise the security in various ways. To address this concern, Mironov and Stephen-Davidowitz introduce the Cryptographic Reverse Firewall (CRF ...

Multi-authority Attribute Based Encryption [PDF]
, 2007 In an identity based encryption scheme, each user is identified by a unique identity string. An attribute based encryption scheme (ABE), in contrast, is a scheme in which each user is identified by a set of attributes, and some function of those attributes is used to determine decryption ability for each ciphertext. Sahai and Waters introduced a single

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Cryptography, 2018 Attribute-based encryption (ABE) is used for achieving data confidentiality and access control in cloud environments. Most often ABE schemes are constructed using bilinear pairing which has a higher computational complexity, making algorithms inefficient
