Abstract :
Cryptographic workflow is a special cryptography system working model in multi-user occasions, in which to encrypt a message according to a certain policy so that only entities fulfilling the policy can perform the decryption of the message. Based on the idea of signcryption a new scheme for KEM supporting cryptographic workflow is proposed. The proposed scheme also is proved secure on receiver security and external security in standard model.
