How to leak authoritative secrets in an elegant way? The paper aims to solve this problem. The desired security properties i.e. Semantic-Security; Recipient-Designation; Verification-Dependence; Designated-Verifier Signature-Verifiability; Public Signature-Verifiability; Recipient-Ambiguity; Designated-Verifier Recipient-Verifiability; Public Recipient-Verifiability; Signer-Ambiguity; Signer- Verifiability are specified in secret leakage. Based on Chow-Yiu-Hui's ID-based ring signature scheme and techniques of zero-knowledge proof, an ID-based controlled secret leakage scheme is proposed. The proposed scheme satisfies all specified security properties and can be used in trust negotiation.
