## Ciphertext Malleability

Ciphertext malleability refers to the ability to modify an encrypted message in such a way that the modification is reflected in the decrypted plaintext. In some cryptographic contexts, this is a vulnerability that must be avoided to ensure data integrity.

However, in specific privacy-preserving protocols, controlled malleability can be used to allow for operations like "re-encryption" or data manipulation without full decryption. This is a delicate balance, as uncontrolled malleability can lead to severe security exploits.

In the context of financial derivatives, any form of malleability must be strictly audited to prevent the tampering of trade data. It is a technical property that developers must master to ensure the robustness of their encrypted financial systems.
