主模式和主动模式（野蛮）区别
他们都是就×××得第一阶段IKE的协商而言。主模式中双方三层交换信息，总共六个包。简单说下1、2个包协商加密和认证算法。3、4个包DH交换。5、6个包提供身份和密钥的验证。主动模式（即你说的野蛮模式）双方进行两次交换，总共三个包。1个包发起方建议SA，发起DH交换。2包接收方接受SA。3个包发起方认证接受方。这是IKE协商方面的一些差别，另外，在主动模式中数据包是在明文中进行交换的，不提供身份保护，而主模式则不然。
 
Main Modes
In main mode, the initiator and recipient send three two-way exchanges (six messages total) to accomplish the following services:
  • First exchange (messages 1 and 2—Propose and accept the encryption and authentication algorithms.
  • Second exchange (messages 3 and 4—Execute a Diffie-Hellman exchange, and the initiator and recipient each provide a pseudo-random number.
  • Third exchange (messages 5 and 6)—Send and verify their identities.
The information transmitted in the third exchange of messages is protected by the encryption algorithm established in the first two exchanges. Thus, the participants' identities are not transmitted in the clear.
Aggressive Mode
In aggressive mode, the initiator and recipient accomplish the same objectives, but in only two exchanges, with a total of three messages:
  • First message—The initiator proposes the SA, initiates a Diffie-Hellman exchange, and sends a pseudo-random number and its IKE identity.
  • Second message—The recipient accepts the SA; authenticates the initiator; and sends a pseudo-random number, its IKE identity, and, if using certificates, the recipient's certificate.
  • Third message—The initiator authenticates the recipient, confirms the exchange, and, if using certificates, sends the initiator's certificate.
