  - IPSec VPN Protocol (GM/T 0022-2014)

 The GM/T 0024-2014 SSL VPN protocol is different from IETF TLS from the follows aspects:
 
  - Current version of TLS is 1.2 (0x0303) while GM/T SSL version is 1.1 (0x0101)
  - The handshake protocol of GM/T SSL is diffenet from TLS handshake.
  - There is an optional different record protocol in GM/T SSL designed for VPN applications.
  - GM/T SSL has 12 ciphersuites, some of these ciphers do not provide forward secrecy.
