“Homomorphic Encryption and Cloud Computing: A Match Made in Heaven”

Homomorphic encryption is a type of encryption that enables computations to be performed on encrypted data without the need for decryption. This allows sensitive data to be kept private while still being able to calculate it, which can be helpful in various scenarios, such as secure cloud computing and privacy-preserving data analysis. In this blog, we’ll explore the concept of homomorphic encryption, its benefits, and some techniques used to achieve it.

What is Homomorphic Encryption?

Homomorphic encryption is a type of encryption that allows computations to be performed on encrypted data without first decrypting it. This is achieved by encoding the data to perform the calculation on the encoded data. The results of the analyses are also encoded, allowing the data to remain encrypted throughout the process. The encoded data can then be decrypted to reveal the results of the computations.

There are two main types of homomorphic encryption: fully homomorphic encryption (FHE) and partially homomorphic encryption (PHE). FHE allows for arbitrary computations on encrypted data, while PHE only allows for specific types of on calc, such as addition or multiplication.
