Abstract: Aiming at the 4-way handshaking protocol defections of the new-generation wireless network security standards 802.11i and the remaining attacks probably exist, this paper studies improved scheme of TPTK technology and re-Nonce. By analyzing the security vulnerabilities of two improved schemes, a new improved design based on digital envelope technology is provided, and it is analyzed and verified.
