Definition ∞ A homomorphic encryption alternative refers to cryptographic methods that permit computations on encrypted data without first decrypting it, offering a substitute for fully homomorphic encryption. These alternatives often provide partial homomorphic properties, allowing specific operations while maintaining greater efficiency. They address the challenge of privacy-preserving data processing.
Context ∞ Discussions about homomorphic encryption alternatives frequently appear in news concerning privacy and data security in blockchain and decentralized applications. While full homomorphic encryption remains computationally intensive, its partial counterparts are being explored for practical uses in secure multi-party computation or verifiable computation. These technologies are crucial for enabling confidential smart contracts and private financial transactions on public ledgers.
