What’s Fully Homomorphic Encryption and How Is It Transforming Cloud Security?
Data breaches are costly — averaging a hefty $4.45 million in 2023 according to IBM’s Cost of a Data Breach Report. With such high stakes, ensuring data security in the cloud becomes is super critical.
At the same time, organisations face the pressure to exploit their data to maximise usability and value extraction. This creates a delicate balance between making data more accessible and more secure.
Let’s look today at Fully Homomorphic Encryption and explore how this encryption method helps organisations secure data and enhance data usability, without compromising on privacy and compliance.
Fully Homomorphic encryption, or FHE for short, is a type of encryption that allows computations to be carried out on encrypted data. In others words, in FHE, data can remain encrypted while being processed.
This is different from most common encryption methods, like symmetric and asymmetric encryptions. Those methods encrypt data in transit and at the rest. But when it comes to processing, they decrypt data, exposing it in plain-text.
