based on the result of the matching, retrieve the secret.

8. The system of claim 7 , wherein the HSM is further operable to:

generate a Secure Sockets Layer (SSL) message including the secret encrypted using the public key; and

send the SSL message to the security gateway.

9. The system of claim 8 , wherein the security gateway is further operable to:

send the SSL message to the server, wherein the SSL message causes the server to decrypt the SSL message and retrieve the secret from the SSL message;

wherein the establishing of the secure session between the security gateway and the server enables the security gateway to exchange encrypted data packets with the server encrypted, wherein the encrypted data packets can be decrypted by the server by decrypting the secret using the public key.

10. A method for providing secure data communication through a security network system, the security network system including a security gateway and at least one Hardware Security Module (HSM), the HSM being a stand-alone hardware device in communication with the security gateway, the method comprising:

establishing, by the security gateway, a client session between the security gateway and a client device, wherein the client session is an unencrypted session;

receiving, by the security gateway, client session information from the client session, wherein the client session information includes an identification of a server with which the client device needs to exchange data;

storing, by the HSM, a public key received by the security gateway from the server based on the identification of the server;

upon the storing of the public key, creating, by the HSM, a secret for encryption and decryption;

encrypting, by the HSM, the secret using the public key of the server;

providing, by the HSM, the secret encrypted by the HSM to the security gateway; and

establishing, by the security gateway, a secure session between the security gateway and the server based on client session data, the secure session being encrypted by the security gateway using the secret, wherein the client device communicates with the server via the client session between the security gateway and the client device and the secure session between the security gateway and the server, wherein the server decrypts the secure session using the public key of the server.

11. The method of claim 10 , wherein the establishing of the secure session comprises:

sending by the security gateway a first request to the server, wherein the first request includes at least a part of the client session information; and

in response to the first request, receiving by the security gateway a security certificate and the public key from the server.

12. The method of claim 11 , further comprising determining by the security gateway that the security certificate obtained from the server is a valid security certificate.
