Definition ∞ A secure decryption protocol is a set of cryptographic rules and procedures that allow encrypted data to be reverted to its original, readable form while ensuring data integrity and preventing unauthorized access. These protocols are fundamental for privacy and security in systems handling sensitive information. They verify the legitimacy of the decryption process, safeguarding data.
Context ∞ In the digital asset sector, secure decryption protocols are critical for systems requiring controlled access to encrypted transaction details or user data, particularly in privacy-focused blockchains or central bank digital currencies. Discussions often involve balancing user privacy with the need for regulated access, such as for anti-money laundering purposes. The design of these protocols is central to achieving selective transparency and regulatory compliance.
