A homomorphic one-way function is a cryptographic primitive that allows computations to be performed on encrypted data without decrypting it, while also being computationally difficult to reverse. This means an operation on the encrypted data yields an encrypted result that, when decrypted, matches the result of the same operation performed on the original unencrypted data. It is infeasible to determine the original input from the output. This combination provides both privacy-preserving computation and data integrity.
Context
The concept of homomorphic one-way functions is frequently discussed in advanced cryptography and its applications to blockchain privacy and secure data processing. While fully homomorphic encryption remains computationally intensive, partial homomorphic properties are seeing limited use in specific privacy-focused digital asset protocols. Future developments aim to reduce computational overhead, making these functions more practical for widespread use in confidential transactions and secure data sharing across distributed ledgers.
Anonymous Multi-Hop Locks (AMHLs) are a new primitive that secures payment channels against fee theft, ensuring both privacy and scalable off-chain transfers.
