Six major network security applications for block chains

Today’s block chain market is still full of security issues, and crimes related to encrypted currency have caused more than $ 14 billion in 2021, which has grown nearly 57% over the previous year. However, compared to the centralized network, the block chain has a lot of innate security advantages.

This will lead to a question: Since the block chain is in design, this innate “safety gene” has the potential for developing network security applications?

“Safety gene” of the block chain

The block chain technology saves the information in the detrogenization network, so the transaction verification process is no longer (completely) depends on a single central organization. The block chain is always distributed, but in terms of permission, size, role, transparency, participant type, and transaction processing methods. Going to the centering structure has inherent security advantages because it eliminates a single point of failure.

The block chain also has several native security features, such as cryptography, public key, and private key, software-mediated consensus, contract, and identity control. These congenial security features provide data protection and integrity by verifying access, verifying transaction records, proves traceability and maintain privacy.

The block chain is strengthened in several ways of network elasticity, transparency, and encryption, which enhances the position of the block chain in the CIA (confidentiality, integrity and availability) security model. However, the block chain is designed and constructed, which means they are still subject to human error, prejudice or exposure based on cases, subversions, and malicious attacks.

Fancy mathematics and software cannot match the chaos of the real world. For this reason, the block chain is only designed to be safe in theory. In practice, the security system that must be designed and implemented to ensure the safety of the zone chain itself.

Here, let’s take a look at what potential for block chains in the network security.

Block zhi six major network security applications

Based on block chains and applications have better safety potential and “gene”, technology is often not decisive. Security leaders must cooperate with products and platform developers to first determine new security features, interaction, and trade-off, and then actively design, test, implement and manage them.

The following is the six major advantages and applications of block chains in security and privacy:

Elasticity and availability

Decenturing infrastructure helps improve the resilience of preventing against attacks and shutdown. Block chain technology can alleviate the following vulnerabilities:

Distributed Information and Communication Technology Network helps reduce data exposure and redirect users during centralized database offline or by attack; deminating DNS helps to achieve redundancy during DDoS attack; in the Internet of Things environment, will Operation and management control disperse to a place away from the central bus, allowing security decisions to be more close to the network edge.

2. Data Integrity

Data on the block chain cannot be tampered with, since the network node is referenced and constructed, and the consensus is required to verify the transaction. In contrast, the link data is more susceptible to attack and tampering. In some highly emphasized data security scenarios and applications, block chain signatures can play a role, such as cross-institutional detrimentary voting, medical and scientific data collaboration, and detrimentary metadata, this is optimized Artificial intelligence in network security is increasingly important.

3. Traceability

Transparency and traceability are the core of the block chain design, but their security advantages differ in different applications. In the supply chain environment, digital distributed books store the trading and product life cycle of trading and cargo data, which reduces the risk of any counterfeit and tamper. In the financial use case, the transparency and invariance of the payment history have reduced the needs of the central agent. The block chain can also improve the security and privacy of transactions such as remittances and cross-border payments.

4. Interactual authentication of software and / or equipment

Transactions on the block chain are not limited to financial areas, which can be used for any verificible interaction. Since the malicious software “update” in the supply chain attack is getting more frequent, it is a good network hygiene habit to authenticate software updates.

Block Chain Hakani can help organizations and product developers verify updates, download, and install software patches. This also helps prevent supply chain attacks, especially software and marginal networking equipment have become the main goal of network attackers.

5. Personal authentication

Several components of the block chain can be applied to identity protection, authentication, access management, etc. These features have many security advantages, including:

Sensitive data protection. Block chain technology can change information stored on the chain, for example, hash values ??rather than personal identity information. Data minimize. The IT team can use encryption techniques (such as zero knowledge certificates or selective disclosure) to reveal the contents necessary to run. Identity theft prevention. The block chain uses an encryption key to verify identity properties and credentials, thereby preventing identity. Multiple signature access control and dispersion management. The block chain can help prevent any single participants from incorrect, take over or fraud.

6. All rights verification

Verify that ownership of online assets is difficult before digital distributed books appear. Even in the real world, the proof process is destroyed, the certification does not always cross the national boundaries, and hundreds of millions of people cannot get stable government identity or financial services. Just as an instead of token (NFT), the artist can perform digital watermark certification for its media, using the encryption key to create unsuccessful authenticity and ownership records in many district block chain, including security advantages, including : Students, teachers and professionals can have their own certificates, not subject to the limitations in the jurisdiction, thereby reducing the counterfeit certificate; creators can retain all the rights to their media, thus improving copyright protection; owners can prove their ownership and Entrustment; manufacturers, such as luxury brands, can attach NFT to their merchandise to ensure authenticity.


The block chain has already shown huge network security potential, and has been used to develop applications that emphasize security, controlled access, accountability, transparency, and efficiency. Before trying to block network security and privacy applications based on the block chain, the company’s security leaders must fully understand the advantages and risks of the block chain security application.
