Like all organizations operating today, your organization must be storing large volumes of data. Some data may just be for logging purposes. Your storage may consist of non-critical data but every organization or company has some blocks of data that they just can not afford to compromise on. This data may include user credentials, bank account information and so much more. In such cases, the safeguarding of data from attackers is the top priority of the organization. Due to the sheer fact that some unwanted hands on such critical data may cause a catastrophe for organizations. That’s where cloud cryptography comes into play.
According to a survey conducted recently, “24% of organizations have hosts missing high-severity patches in the public cloud. ” – Redlock
What can we do about the critical data?
One can put up firewalls, store critical data on isolated networks but in today’s digital world, there is no protection that can not be compromised. Therefore companies encrypt their data. So even if the attacker gets his or her hands on the data, it is of no use to them due to the data being unusable.
What is Cloud Cryptography?
Cloud uses an encryption technique called cloud cryptography. Now doesn’t that make life easy? Nowadays with large and small businesses shifting rapidly to the cloud for all kinds of resource and storage requirements, they need to be sure their data is in safe hands and there’s no better alternative to cloud cryptography for the security concerns of big companies. This is why there’s an unprecedented shift towards the cloud.
This smart technique only allows decrypted data access to cryptographic key holders. This restricts a business’s data to their eyes only. The high-level authentication process of the cloud ensures data safety.
You can have surety that your sensitive data is secured with the cloud. To top it all, encrypting data on the cloud has no inverse effect on the time it takes to access your data. So, whether you want to pass data from one cloud medium to another or simply just store it, the cloud encryption solutions will encode your data at all times to keep it secure.
How does cloud cryptography work?
The cloud cryptography technique takes multiple measures to make sure your data is safe and sound, acting as a solid wall against attacks. This powerful encryption tool is the need of the hour for businesses in today’s modern age. So, you can say a long farewell to data breaches or hacking attempts because cloud cryptography is your safeguard against all forms of attacks.
Just like normal cryptography, cloud cryptography is also focused on encryption. The only difference being you do not need to put long hours and effort into securing your data. With a single click of the button, the cloud handles it all for you. The cloud encrypts your text into ciphertext which only authenticated personnel in your organization can access through a private key which they must use to decode the ciphertext.
Furthermore, the cloud has taken encryption to a new level. On the cloud, you can encrypt data in four different ways!
Storing the encrypted data onto the cloud is a safety option. However, you’re fully responsible for the security. This is called pre-encryption. However, on the other hand, if you want to leave this work to cloud cryptography, it may be carried out for you very efficiently.
Symmetric key cryptographic algorithm
Through the symmetric key cryptographic algorithm, you can give special authorization to users who are allowed to access the data with a single unique key only after they are authenticated. An example of such kinds of algorithms is the Advanced Encryption Standard.
ASymmetric key cryptographic algorithm
An asymmetric key cryptographic algorithm is also an option. This technique uses two keys instead of one. One used to encrypt and the other used for decryption purposes such as the Digital Signature Algorithm.
Lastly, hashing is another technique you may use. It similarly utilizes two keys for encryption and decryption. But indexing uses hashing technique.
As you can see, there are various methods to safely encrypt and store your critical data according to your needs through cloud cryptography. Not only does this significantly reduce cybercrime but you are instantly alerted to any attempt to alter or change data by an unauthorized user.
Businesses prefer cloud encryption due to the fact that it is not only easy to store data but sending critical data from one end to another constantly requires high-end encryption and the cloud possesses the tools to provide just that.
However, as much of a dream as this sounds like, one must always be knowledgeable about the drawbacks. For starters, this is a costly service and secondly recovering data may become a hassle even for authorized people if you tend to get over ambitious and overprotect your data with all the resources you can get your hands on.
So choose your encryption technique wisely according to your data and storage requirements.
