In this article, we will delve into the key components of NuLink's mission and explore how it combines advanced technology to reshape the landscape of data privacy and protection. Let's take a look.

Data Availability

Protecting data privacy is the core mission of NuLink. NuLink is committed to ensuring the protection of personal information. To achieve this, it focuses on addressing data availability issues, which can be divided into the following key parts.

1. First of all, it is important to empower users with the ability to verify whether they have the necessary data before making a request. This ensures that individuals can confirm that users can provide the specific data they need. The ultimate goal is to increase transparency and maintain trust between users.

2. The key is to establish a reliable method for verifying the authenticity of encrypted data. Encryption plays a crucial role in protecting sensitive information, but it may pose challenges in ensuring the accuracy and integrity of the data itself. To overcome this obstacle, a technology called Zero-Knowledge Proof is used in the NuLink network. Zero-Knowledge Proof is a complex method that guarantees the ability to verify the data processing and computing operations of all functional nodes (including storage nodes, computing nodes, and proxy nodes) in the NuLink network. It ensures that these different components of the network can perform their tasks while maintaining transparency and accountability.

3. In addition, the method also integrates an additional layer of security. Before granting access to encrypted data, the data owner must provide zero-knowledge proof. Regardless of the specific encryption scheme used, this proof can serve as evidence corresponding to the encrypted data and its original plaintext form.

Data Sharing

One important aspect to note is how to maintain the security of data when it is shared with external parties. It is crucial to ensure that the data remains intact and uncompromised throughout the entire transmission process, and that access is limited to individuals authorized by the data owner.

To address this challenge, NuLink has adopted advanced technologies, such as:

●Proxy Re-Encryption, abbreviated as PRE.

Based on identity encryption, abbreviated as IBE.

Based on attribute encryption, abbreviated as ABE.

This process first encrypts the data on the user side, adding an extra layer of protection. Then, PRE, IBE, or ABE algorithms are used to grant authorized parties access to the encrypted data.

With the help of these encryption methods, the authorized recipient can decrypt the data using their private key based on the specific encryption scheme used. This ensures that only the data owner and authorized parties have the ability to access the original data.

Data Calculation

NuLink is actively addressing another challenge in data computation, which is concerns about privacy. In some cases, particularly those involving edge computing or machine learning, data owners may be hesitant to grant full access to their datasets. Instead, they may prefer to authorize computations on specific models, allowing authorized parties to receive only the computation results without accessing the raw dataset.

In order to solve this problem, NuLink will adopt Fully Homomorphic Encryption technology (FHE) to promote privacy-preserving data computation. FHE is a powerful encryption technology that allows computation on ciphertexts, ensuring that data remains encrypted throughout the entire computation process.

Its working principle is as follows: Initially, the data set is encrypted and securely transmitted to the designated computing provider. These providers perform the required computations, such as running machine learning prediction models, in turn, without accessing plaintext data. The computation results are then encrypted and returned to the authorized party for decryption, ensuring the privacy and confidentiality of the data throughout the entire computation process.

By utilizing FHE technology, NuLink enables data owners to retain control over their sensitive information while still benefiting from the power of data computation. This approach strikes a balance between privacy and practicality.
