Types of Homomorphic Encryption
Homomorphic encryption is a form of encryption that allows computations to be carried out on ciphertext, generating an encrypted result that, when decrypted, matches the result of operations performed on the plaintext. There are several types of homomorphic encryption, each with varying degrees of complexity and application. These types can generally be categorized into partial homomorphic encryption (PHE), somewhat homomorphic encryption (SHE), and fully homomorphic encryption (FHE). Partial homomorphic encryption supports a limited number of operations on encrypted data. Somewhat homomorphic encryption extends this to support a greater, but still finite, number of operations. Fully homomorphic encryption enables arbitrary computations on encrypted data, providing the highest level of flexibility and security but also requiring more computational resources.
There are three primary types of homomorphic encryption: partial, somewhat, and fully homomorphic encryption (FHE). Each type offers different levels of computational capability on encrypted data, catering to varying security needs. Partial homomorphic encryption supports a single type of operation, such as either addition or multiplication. Somewhat homomorphic encryption allows a limited set of operations, providing a balance between computational efficiency and security. Fully Homomorphic Encryption (FHE) enables arbitrary computations on encrypted data, offering the highest level of security while also posing the greatest computational challenge.
Each type of homomorphic encryption holds merit, depending on the requirements of the application. Partial homomorphic encryption is simpler and less computationally intensive, making it suitable for applications that require fewer operations. Somewhat homomorphic encryption expands the range of operations possible while still maintaining a manageable computational load. Fully homomorphic encryption (FHE), while the most secure and versatile, requires significant computational resources and is often utilized in scenarios where security is paramount. Understanding the nuances and capabilities of each type is crucial for organizations seeking to implement homomorphic encryption effectively in their Gen AI applications.
