1. A method of establishing security within an untrusted network, comprising:

  • providing a digital certificate associated with a first security apparatus associated with a first computerized host device;

    sending said digital certificate via a message to a second security apparatus associated with a second computerized host device;

    receiving at said first security apparatus and from said second security apparatus an initialization vector and a cryptographic element which is encrypted, said cryptographic element having been generated by said second apparatus after receiving said digital certificate;

    decrypting said encrypted cryptographic element to obtain access to said encrypted cryptographic element;

    verifying an integrity of a second message used to transmit said cryptographic element using a digital signature, at least a portion of said second message wrapped along with said digital signature;

    initializing an encryption algorithm using the initialization vector; and

    encrypting one or more datagrams exchanged between the computerized host devices using the decrypted cryptographic element.
