Introduction<\/h1>\n\n\n\n

Every day, we need to encounter a lot of sensitive and valuable digital data that needs to be encrypted when it is being transmitted from source to destination so that, eavesdroppers can\u2019t extract the information during the transmission. At the same time, we need to encrypt data saving on the cloud for any organization.<\/p>\n\n\n\n

However, we must decrypt those data prior to use for any project. As soon as, we decrypt data it becomes vulnerable to hackers. This is an ongoing issue for data encryption.<\/p>\n\n\n\n

Homomorphic encryption is an advancement in the era of cryptography.<\/p>\n\n\n\n

What is Homomorphic Encryption?<\/h1>\n\n\n\n

The main purpose of homomorphic encryption is to allow computation on encrypted data. In that way, data can remain encrypted while it is processed. In any vulnerable environment, homomorphic encryption is a revolutionary algorithm to accomplish the task of processing encrypted sensitive data without decrypting it.

A homomorphic cryptosystem is another form of public encryption in that it uses a public key to encrypt data and allows only the individual with the matching private key to access its encrypted data. However, even though it is another form of public encryption, but it uses a different algebraic system to allow a variety of computations on the encrypted data.<\/p>\n\n\n\n

In mathematics, homomorphism explains the transformation of one data set into another while preserving relationships between elements in both sets. This encryption method works well with integer data while using addition and multiplication as the operational functions and during that process, encrypted data can be manipulated and analyzed as though it\u2019s in plaintext format without being decrypted.<\/p>\n\n\n\n

Types of Homomorphic Encryption<\/h1>\n\n\n\n

There are three types of homomorphic encryption. The primary difference between them is related to the types and frequency of mathematical operations that can be performed on the ciphertext. The three types are:<\/p>\n\n\n\n
