An anonymous signcryption scheme based on one-off public key

One-off public key can not only achieve the security of user's privacy, its traceability can also reveal the malicious user's identity together with the trusted center. 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.
