What is Confidential Computing and What is the Use of It?

As the risk of cybercrimes increases, companies try to give more security to sensitive information. And here comes Confidential Computing which gives assurance to the companies that their sensitive data is safe. 

Which encourages them to rely on public cloud services. In this article, we will discuss the whereabouts of Confidential Computing and its uses.

What is Confidential Computing?

Confidential Computing is nothing but a cloud computing technology. During data processing, it isolates the sensitive data in a protected CPU enclave.

It is only accessible to authorized programming code. For an unknown source, it will be invisible or unknowable.

How Confidential Computing Works

When you run data through an application, the data needs to be unencrypted. Otherwise, the application won’t be able to read the data. But unencrypted data is vulnerable to other malicious exploits.

This method helps to solve the problem. An encrypted data can be read through this method. An enclosed territory in the CPU called TEE or hardware-based Trusted Execution Environment keeps this sensitive data safe. 

Trusted Execution Environment has encrypted keys and it makes sure that the particular encrypted data can only be accessible by a particular application code. If any other code tries to go through from this process or maybe if the code is hacked or altered, the code will deny its access.

By this procedure, that can protect sensitive data. Trusted Computing consists of six key points and obviously, these are technology concepts.

1. Endorsement Key

This key makes sure that a secure transaction is done by a trusted entity. Every Trusted Platform Module needs to provide a proper identity by signing a random number created by the Trusted Computing Group. Thus, an untrusted entity can not be entered.

2. Secure Input and Output

Secure input and output without any disruption is another key that is maintained. Confidentiality protects the data from unauthorized viewing and access. In today’s world, It is the solution to secure the data in use.

3. Memory Protection Execution

The Trusted Execution Environment or TEE, the enclosed territory which contains the sensitive data can not be fully accessible even for the operating system.

4. Sealed Storage

Sealed storage is configured with a particular hardware and software combination which protects sensitive data from going into the wrong hands. So, if someone tries to alter, delete, copy or manipulate the particular data they need to know the right combination.

5. Remote Attestation

Remote attestation is a method by which an authorized host can detect any hardware or software configuration changes done by a computer user.

6. Trusted Third Party

Maintaining the “trusted platform” was very much important for the TCG technology developers. While using a third-party platform, the user needs to share some personal information about the system by giving his/her EKpub information.

With the help of EKpub information, the data can go into the wrong hands. So, the Trusted Computing Group developers create a certified Attestation Identity Key. This method does not require the EKpub information for the third-party platform. This is called DAA or Direct Anonymous Attestation process.

Application of Confidential Computing

Obviously, the first application of Confidential Computing is secure sensitive data. It can be companies’ confidential data or educational data or some other sector’s information. So, clearly, this method is useful in every sector.

Not only the sensitive data, but it also secures the business logic, machine learning algorithms, analytic function or maybe the entire application.

The two business partners can create new cloud solutions without sharing confidential information with each other.

In the gaming world, it can prevent unfair advantages if some player tries to do so by checking the players connecting servers. If any player is connected to an unmodified copy of the software, it can detect.

It has some drawbacks. This method won’t allow a user to modify software without proper permission or a user is unable to override or may be vulnerable to vendor withdrawal of service but to protect very confidential data we could ignore these little drawbacks. So, it can conclude that Confidential Computing is essential in the business field, educational fields, and every other Private sector.
