Introduction

NuLink network is a decentralized solution for privacy-preserving applications developers to implement best practices and best of breed security and privacy. The NuLink platform provides endpoint encryption and cryptographic access control. Sensitive user data can be securely shared from any user platform to cloud or decentralized storage and access to that data is granted automatically by policy in Proxy Re-Encryption or Attribute-Based Encryption. For the data user on the other side, Zero-Knowledge Proof can help them verify the data source. In more advanced privacy-preserving use cases, NuLink uses Fully Homomorphic Encryption to customize enterprise-level data computation services.

Our Technologies

By integrating best in class technologies we are building a strong technology foundation. The technical solutions provided by NuLink cover three main categories.

To ensure the availability of data in ciphertext form. The crypto techniques used here mainly include Zero Knowledge Proof. Privacy-preserving data sharing. The general method is to encrypt data and let the data owner control access to it. The technologies include decentralized encrypted storage, proxy re-encryption, identity-based encryption and attribute-based encryption, etc. Privacy-preserving data computing, which involves the integration of certain privacy computing capabilities into smart contracts. The technologies used include multi-party secure computing, homomorphic encryption and so on. These three kinds of technical solutions can provide privacy-preserving applications in many fields, such as Decentralized Finance (DeFi), healthcare, social networks, Digital Rights Management, etc
