But, the real problem of IPsec is that it expected some PKI could have provided the end to end security. However, the real myth is that PKI depends on security of a breakable chain of CAs, which is not the end to end security. For the end to end security, only the end systems requiring the security are required to deploy mechanisms for the security, which means it is not necessary to mandate all the end systems deploy some security protocol.
