At present, At present, being proposed by many scholars, most one-off public key schemes, however, still not secure at present- whose private key , certification and signature been counterfeited by malicious users. The research of anonymous signcryption based on one-off public key is almost vacant. This paper proposes a new anonymous signcryption scheme based on one-off public key which has an efficient algorithm, and what's more , whose anonymity and traceability can prevent attack from untrusted clients and malicious users.
