Homomorphic encryption, also known as homomorphic encryption, is a type of encryption that allows computations to be performed on encrypted data without decrypting it first. This means that the encrypted data can be processed and analyzed in the same way as if it were in plaintext, while still maintaining its confidentiality.

Basic Concepts

  • Encryption: The process of converting plaintext data into ciphertext to prevent unauthorized access.
  • Decryption: The process of converting ciphertext back into plaintext.
  • Homomorphic Encryption: A form of encryption that allows computations to be performed on ciphertext without the need for decryption.

Types of Homomorphic Encryption

  1. Somewhat Homomorphic Encryption (SHE): Allows a limited number of operations on ciphertext, such as addition and multiplication.
  2. Fully Homomorphic Encryption (FHE): Allows any number of operations on ciphertext, including complex computations.

Applications

Homomorphic encryption has various applications, including:

  • Secure Cloud Computing: Protecting data stored in the cloud without compromising its confidentiality.
  • Electronic Voting: Ensuring the privacy of votes cast in electronic voting systems.
  • Healthcare: Protecting patient data while still allowing authorized access for analysis.
