A New Attack on NTRU Public Key Cryptosystem Depend on Using Public Key and Public Information [PDF]

, 2010
This paper proposed a new method to attack the NTRU cryptosystem [Hof00a,Hof98b]. It tried to exploit the public information about the parameters of NTRUcryptosystem and using the public key, to recover the private keys without delvingin the detail of ...

Digital watermarking scheme exploiting non-deterministic dependence for image authentication [PDF]

, 2006
Watermarking schemes for authentication purposes are characterized by three factors: security, resolution of tamper localization, and embedding distortion.

Public key cryptography based on tropical algebra [PDF]

, 2023
We analyse some public keys cryptography in the classical algebra and tropical algebra. Currently one of the most secure system that is used is public key cryptography, which is based on discrete logarithm problem.

Security analysis and improvement of strongly secure certificate less signature scheme

Tongxin xuebao, 2014
By analyzing the security of strongly secure certificateless signature scheme proposed by Wang Yafei et al, the problem that the scheme could not resist public key replacement attack under dishonest KGC was pointed out.

Quantum Indistinguishability for Public Key Encryption [PDF]

, 2021
In this work we study the quantum security of public key encryption schemes (PKE). Boneh and Zhandry (CRYPTO\u2713) initiated this research area for PKE and symmetric key encryption (SKE), albeit restricted to a classical indistinguishability phase ...

Strong non-repudiation certificateless scheme with an aggregate signature in vehicular ad-hoc network

Franklin Open
In Vehicular Ad-Hoc Networks (VANETs), a Certificateless Aggregate Signature (CLAS) scheme with a conditional anonymity authentication meets both anonymity and security requirements.

Leakage-Resilient Certificateless Public Key Encryption

, 2013
In certificateless public key encryption (CL-PKE), the Private Key Generator (PKG) keeps a master secret key to generate a partial private key corresponding to a user's identity.

Message transmission for GH-public key cryptosystem

, 2014
In this paper we propose an ElGamal type encryption scheme based on the concepts of public key cryptosystem over cubic finite field extension proposed by Gong and Ham (GH).

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.
