What’s The Future Of Cloud Encryption Technology?

Media Division | April 10, 2015

Enterprises that have made cloud computing an essential part of their critical infrastructure are experiencing real benefits, but they also continue to experience new security challenges, which conventional security perimeters fail to address.

While every cloud service provider offers built-in security, cyber criminals have proven that popular cloud storage can be easily breached, which shows that current industry standards offer insufficient security against DDoS, botnet, man-in-the-middle, and other cyber attacks.

As a result, enterprises must take measures to protect their data if they use the cloud. One of the answers to this fragile security situation is cloud encryption technology. It solves many control challenges corporations face during their use of the cloud.

When cloud service providers are breached, for example, the encrypted data remains unreadable to cyber criminals as long as encryption keys are in control of the enterprise. Also, encryption focuses on securing corporate data rather than infrastructure, so it ensures data is safe even if hackers are able to exploit hardware vulnerabilities.

Is cloud encryption 100% foolproof?

There’s no security method that’s 100% foolproof, and encryption is no different. This security measure includes the management of encryption keys; and inappropriate management has become one of the leading causes of data breaches.

As more organizations integrate encryption, the number of keys to be managed has also increased. Those who offer data encryption are neglecting the fact that management keys for the client is also an essential part of the encryption service, while organizations implementing encryption are finding it difficult to separate encryption data and the keys.

Also, regulations such as the HIPPA and PCI DDS are evolving and becoming stringent. So organizations need to keep up with the way sensitive data shapes up, or they could end up facing legal penalties and other serious consequences due to non-compliance.

The fact that encryption is becoming a big priority in retail and other sectors after last year’s data breaches is bringing a change in enterprise security landscape. New emphasis on encryption itself is leading to some interesting developments.

So what does the future hold?

New technologies that focus on different encryption forms could be the difference maker, but they would have to be supported by cloud computing providers.

One interesting development is of homomorphic encryption. It gives organizations flexibility with data storage; it allows them to keep a database in the cloud, use it, and keep it encrypted during the process. So if more than a single encrypted value is added, the result will still be encrypted. This technology can enable enterprises to decrypt data without knowing the results of the original data.

Convergent encryption is another new technology; it is the process in which unencrypted data of an organization is utilized to generate the key that will be used for encryption. So in the process, two similar files are created, and they remain similar after being encrypted, but no one can read them without the original file. With convergent encryption, cloud service providers can scan pirated files without touching the private data of their clients.

With so many companies choosing cloud storage solutions, encryption will become a commonplace and new developments will put it in par with firewalls and antivirus protection. Expect more developments in encryption technology as adoption grows.
