Provable security signcryption scheme and its hybrid construction
Yuqing Zhang · Journal of Xidian University · 2009
By using the Tag-KEM/DEM hybrid encryption technique and based on a provable security signcryption hybrid construction SCTK/DEM proposed by Bj￠rstad in 2006,a new signcryption scheme is given.By analyzing its hybrid construction,it is obtained that the proposed signcryption scheme is up to the SCTK/DEM construction.So,it has provable security.Moreover,compared with the famous signcryption scheme SCS,the high efficiency of our proposed scheme is shown at the same time.
