Homomorphic Encryption and how it is useful


Homomorphic encryption is a form of which allows us to perform computations on encrpyting data. Moreover, it provides confidentiality, enabling useful tasks for accomplishment. In addition, it has hugely valuable capability.

Firstly, this cryptosystem uses public key for encryption of data. And allows only the individual with matching private key to access the unencrypted form.

In addition, this method works best with integer data.

Types of Homomorphic Encryption

Let us take a look at the types of this encryption.

  • Partially Homomorphic Encryption
  • Somewhat Homomorphic
  • Fully Homomorphic Encryption

Firstly, partially (PHE) allows to select only mathematical functions for performing encryption on data. This means only one operation like addition or multiplication is there. Moreover, this encryption with multiplicative operation is foundation for RSA algorithm.

Secondly, somewhat allows to select either addition or multiplication up to a certain complexity.

Thirdly, fully helps to make data secure and accessible at the same time. It provides both addition and multiplication any number of times. Moreover, it can also handle arbitary computations.

Applications of Fully Homomorphic Encryption

Fully homomorphic encryption has various applications. Let us take a look at some of them.

  • Enables Data Analytics in Industries
  • Secure Data Storage in Cloud
  • Improves Transparency and election security

This encryption allows encryption of data and outsourcing it to commercial environments for research purposes. Moreover, it also protects data privacy. It is useful for industries including IT, retail and services.

In addition, we can secure data storage in cloud. It retains the ability to calculate and search cipher information that we can later decrypt without compromising integrity.


  • Its support for multiple users.
  • Large complexity for algorithms
  • Computational overhead


In conclusion, we have learnt about encryption and its applications. We have also learnt about its types.

Moreover, the concept of encryption promises for real world applications use in industries.
