Linear-Only Encryption

Definition ∞ Linear-only encryption refers to cryptographic schemes where decryption operations are limited to a sequential or linear processing of encrypted data. This contrasts with more advanced encryption methods that allow for non-linear computations or operations on ciphertext without decryption. Such a limitation can impact the flexibility and functionality of data handling.
Context ∞ While not a common term in daily crypto news, understanding linear-only encryption is relevant for deeper technical discussions concerning privacy-enhancing technologies within blockchain. Concepts like homomorphic encryption, which allows computation on encrypted data, represent a departure from linear-only limitations. News covering advanced cryptographic protocols or secure multi-party computation might indirectly touch upon the constraints or advancements beyond linear-only encryption.
