Why is Cryptography So Important for Data and Cloud Security?

What is Cryptography

Cryptic messages always have the ability to keep your data safe. In the times of war, Cryptography used a lot to send in cryptic messages. So even in the worst case scenario, if the message somehow went into the wrong hands, the plans and strategies still remained guarded.

The message would not make sense to any person who cannot decode it. Now that we deal with everyone in the technological world, this cryptic space now called cyberspace.

This means, cryptography is still very much important and paramount these days. The very nature of the cloud solutions, is what further enhances the importance of cryptography in the cloud security world. In the case of public cloud, data normally is in the hands of Cloud Service Provider (CSP).

With this blog post, we will discuss the concept of cryptography, the two major types, and how we can use it in today’s world.

What is Cryptography?

It usually known as the method by which we can hide or code our information. This way only the person who needs to understand the information can understand it. This method has extensively used since many years to keep the information safe.

How does Cryptography work in the IT Sector?

An encryption technique used first, rather than sending commands, sensitive data, or other information over the internet immediately. As a result, the communication becomes unintelligible to both the intended and unexpected recipients.

This is when the exciting part starts. The information will encrypted, but the intended recipient will have the decryption key—the algorithm that once more transforms the data into a form that the intended user can comprehend.

If a cyber criminal succeeds in obtaining this data or information while it transmitted to the intended recipient, it will remain utterly unreadable to them without the decryption key.

Among Encryption methods, the two most used methods are Symmetric and Asymmetric encryption. Let’s discuss both of them:

Symmetric Encryption

The same key or algorithm used for both encryption and decryption in this more straightforward encryption technique. This approach is easier to use, but it presents difficulties when it comes to safely giving the key to the designated recipient.

Asymmetric Encryption

This approach gives the entire procedure an extra degree of security. The public and private keys, which are two different sets of keys / algorithms, employed in this encryption technique. Sending the data securely is possible for any user who possesses the public key.

On the other hand, this data can only decrypted by the owner of the private key. Therefore, only those who intended are in possession of the private keys. This strategy also greatly simplifies the key management process.

Let’s now quickly discuss the most popular encryption schemes that applied in practical settings.

Encryption at Rest

One of the most popular forms of encryption is this one. As the name implies, this method will maintain your private information encrypted as long as no software or application is using it. The data will no longer encrypted after use.

In-Transit Encryption

This kind of encryption adds an extra layer of protection. While your data or information is in transit, this kind of encryption keeps it indecipherable. This shields your data during transit from theft, loss, and unwanted access.

Encryption is use

Since it keeps your critical data or information encrypted while it used, this is one of the safest forms of encryption. Therefore, the resource intensity of encryption techniques increases with their nature and application surface.

The Importance of key management

This perspective suggests that encryption is primarily concerned with keys and algorithms. Your entire encryption environment, whether it hosted on-premises or in the cloud, will more effective the better safeguarded your key management and controls are.


Regardless of the kind or technique of encryption you use, the costs of data loss, breaches, and theft far exceed the expenses of using encryption. Businesses will therefore need to take a wider view when examining this security measure.

Distinguishing the encryption key management process from the service provider is usually a smart approach, particularly when it comes to cloud computing. This offers the deploying organization enhanced security as well as data autonomy.
