Using Abelian Varieties to Improve Pairing-Based Cryptography [PDF]

Journal of Cryptology, 2008
In this long and quite technical paper the authors study several aspects of Pairing-Based Cryptography. Bilinear pairings (Weil and Tate pairings) on elliptic curves or higher dimensional abelian varieties are used in Cryptography both in a constructive and destructive way, see [Handbook of elliptic and hyperelliptic curve cryptography.

Systematizing core properties of pairing-based attribute-based encryption to uncover remaining challenges in enforcing access control in practice

Designs, Codes and Cryptography, 2022
Attribute-based encryption (ABE) cryptographically implements fine-grained access control on data. As such, data can be stored by an entity that is not necessarily trusted to enforce access control, or an entity that is not even trusted to have access to

On the ρ-values of complete families of pairing-friendly elliptic curves

Journal of Mathematical Cryptology, 2012
The parameter ρ of a complete family of pairing-friendly elliptic curves represents how suitable some given elliptic curves are in pairing-based cryptographic schemes. The superiority of the curves depends on how close ρ is to 1.

Efficient and Anonymous Certificateless Multi-Message and Multi-Receiver Signcryption Scheme Based on ECC

IEEE Access, 2019
As the further extension of the multi-receiver signcryption, the multi-message and multi-receiver signcryption allows a sender to simultaneously signcrypt different messages for different receivers in only one logic operation, which makes it more ...

Heuristics on pairing-friendly elliptic curves

Journal of Mathematical Cryptology, 2012
We present a heuristic asymptotic formula as for the number of isogeny classes of pairing-friendly elliptic curves over prime fields with fixed embedding degree , with fixed discriminant, with rho-value bounded by a fixed such that , and with prime ...

Implementing Health‐Related Quality of Life Assessment in Pediatric Oncology: A Feasibility Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background There is growing interest in embedding health‐related quality of life (HRQoL) assessment and patient‐reported outcome measures (PROMs) within clinical cancer care. This study evaluated the feasibility, acceptability, and usability of implementing an electronic PROM (ePROM) platform to measure HRQoL in children with cancer ...

Fast AVX-512 Implementation of the Optimal Ate Pairing on BLS12-381

Transactions on Cryptographic Hardware and Embedded Systems
Non-degenerate bilinear maps on elliptic curves, commonly referred to as pairings, have many applications including short signature schemes, zero-knowledge proofs and remote attestation protocols.

Treatment Decision‐Making Roles and Preferences Among Adolescents and Young Adults With Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Decision‐making (DM) dynamics between adolescents and young adults (AYAs) with cancer, parents, and oncologists remain underexplored in diverse populations. We examined cancer treatment DM preferences among an ethnically and socioeconomically diverse group of AYAs and their parents.

On the Security of Certificateless Signature Schemes

International Journal of Distributed Sensor Networks, 2013
Wireless Sensor Network (WSN) has proved its presence in various real time applications and hence the security of such embedded devices is a vital issue. Certificateless cryptography is one of the recent paradigms to provide security.

Arithmetic Operators for Pairing-Based Cryptography [PDF]

, 2007
Since their introduction in constructive cryptographic applications, pairings over (hyper)elliptic curves are at the heart of an ever increasing number of protocols. Software implementations being rather slow, the study of hardware architectures became an active research area. In this paper, we first study an accelerator for the i¾?
