WHY TRUSTED COMPUTING IS THE FUTURE OF DATA SECURITY
The need to enjoy privacy and not feel like you are being spied on is crucial in the technological age. In the twenty-first century, every aspect of life deals with digital resources, which in turn deal with data processing. Hence, the need to maintain privacy while transmitting data is crucial.
In 2008, the blockchain concept was created, and it became a widely accepted solution for privacy and data security. The blockchain achieves its said anonymity through decentralization. It fosters a trustless transaction system where people can communicate with each other and transact with each other without the need for trust, as there are several miners who will validate each transaction on the blockchain. Scams cannot happen because the majority of the miners will reject any untrue transaction, and it will never appear on the blockchain’s ledger. The blockchain uses a consensus mechanism, which means that the majority of the nodes (miners) in a network need to agree to the same thing before any transaction is validated, and in the end, a transaction hash which is published on the blockchain is produced. This transaction hash in no way shares information about the sender or the recipient, and hence the transaction stays anonymous.
Although blockchain technology preaches anonymity and decentralization, several shreds of evidence have shown that the blockchain isn’t truly anonymous but pseudonymous.
The blockchain ledger is public, and for this reason, there is a tendency for people’s privacy to suffer a breach. The internet exposes several private information such as the IP address, location, Internet service provider, and even email addresses could be exposed on the internet. The moment a link can be established between the transaction and any private information, then privacy becomes breached, and individuals could be subject to theft or extortion. So it becomes obvious that the blockchain hasn’t sufficiently addressed the privacy issues we face, and we need a sure solution for data security, which leads us to the concept of trusted computing.
Trusted computing isn’t an entirely new technology as it is being used in many current computer systems. In essence, trusted computing allows the data to dictate who or what has access to it. So, a piece of data can control the software and operating systems that can read or rewrite its content.
The basic components of trusted computing are:
- Memory Curtaining: This helps encrypt the data content such that any associated program cannot read or rewrite its content.
- Sealed storage: Trusted computing also involves sealed storage, which means that the data is sealed by default, and when it is needed for interaction, then it becomes temporarily unsealed for interaction before returning to its sealed state.
- Remote Attestation: With trusted computing, the data to be accessed first checks out the other party and decides whether to share data or not. So, you can be sure that your data will only be shared if you trust the third party enough.
The concept of trusted computing can be used to solve the blockchain’s pseudonymity and offer true anonymity through a technology called the Trusted Execution Environment (TEE). The ZeroHybrid network aims to promote trusted computing via TEE technology by storing data in an ARM module which treats data as sensitive, protecting them with memory curtaining, sealed storage, and remote attestation such that no one can gain access to data without the permission of the person who wrote the data.
This helps the blockchain maintain its ledger; however, each transaction becomes end-to-end encrypted, and only people who have permission to a certain transaction can gain access to it.
Blockchain and decentralization are widely regarded as the future of humanity, and to achieve this, we must improve privacy on the blockchain with the use of trusted computing.
About ZeroHybrid Network:
ZeroHybrid is the industry’s first ARM-based decentralized trusted computing network that can use mobile devices to provide computing power. ZeroHybrid utilized the wildly spread ARM chipsets to implement TEE, which guarantees the computation process through the power of the hardware, enabling a trusted environment not able to be modified by other software. With the diversity of ARM chips and wide range of application scenarios, to form a safe, credible, and decentralized computing environment.
