Abstract: Multi-user communication is the major model of present information exchange and to improve communication security and to solve the problem of communication efficiency is the key of present research. Attributed-based signcryption ensures the confidentiality and integrity of the information during communication and realizes the sending of information through one-step operation, thus improving the efficiency of signcryption. By using secret sharing model and bilinear pairs, an efficient fuzzy attribute-based signcryption scheme was presented, and based on DMBDH and CDH problem, the confidentiality and unforgeability of the scheme were proved. Meanwhile, it meets public verifiability and short ciphertext. Compared with other analysis, the amount of computation of signcryption and designcryption is only (n+3)e and ne+(n+4)p, far less than those of other similar schemes and this realizes the efficiency of computation.
