Unimodular homotopy algebras and Chern-Simons theory [PDF]
, 2015 Quantum Chern-Simons invariants of differentiable manifolds are analyzed from the point of view of homological algebra. Given a manifold M and a Lie (or, more generally, an L-infinity) algebra g, the vector space H^*(M) \otimes g has the structure of an ...

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

Electronic voting protocol from bilinear pairings
Revista Facultad de Ingeniería Universidad de Antioquia, 2013 Electronic voting has been an active research area since two decades, which involves using information systems and cryptographic schemes in order to reduce costs and human mistakes as well as increase process speed, without discard its security. In the literature there exist some proposals, which are based on the difficult to resolve mathematical ...

An identity-based key infrastructure suitable for messaging applications [PDF]
, 2007 —Identity-based encryption (IBE) systems are relatively recently proposed; yet they are highly popular for messaging applications since they offer new features such as certificateless infrastructure and anonymous communication. In this paper, we intended

Limited Verifier Signature from Bilinear Pairings [PDF]
, 2004 Motivated by the conflict between authenticity and privacy in the digital signature, the notion of limited verifier signature was introduced [1]. The signature can be verified by a limited verifier, who will try to preserve the privacy of the signer if the signer follows some specified rules. Also, the limited verifier can provide a proof to convince a

, 2016 The Beauville-Fujiki relation for a compact Hyperk\"ahler manifold $X$ of dimension $2k$ allows to equip the symmetric power $\text{Sym}^kH^2(X)$ with a symmetric bilinear form induced by the Beauville-Bogomolov form.

Outsourced ciphertext-policy attribute-based encryption with partial policy hidden
International Journal of Distributed Sensor Networks, 2020 Attribute-based encryption is an efficient and flexible fine-grained access control scheme. However, how to realize the attribute privacy concerns in the access policy and optimize the heavy computing overhead have been not adequately addressed.

Gutzwiller Projected wavefunctions in the fermonic theory of S=1 spin chains
, 2012 We study in this paper a series of Gutzwiller Projected wavefunctions for S=1 spin chains obtained from a fermionic mean-field theory for general S>1/2 spin systems [Phys. Rev. B 81, 224417] applied to the bilinear-biquadratic (J-K) model.
