Protocol translation

摘要

A system and method for securing data by receiving encrypted data at a security appliance transmitted from a client, wherein at least a portion of the encrypted data is encrypted according to a first encryption protocol, and wherein the encrypted data is transmitted to the security appliance according to a first data transfer protocol. The encrypted data is then decrypted at the security appliance, wherein at least a portion of the decrypted data is re-encrypted according to a second encryption protocol at the security appliance. The re-encrypted data is transmitted from the security appliance to a storage device, wherein the re-encrypted data is transmitted according to a second data transfer protocol that is different than the first data transfer protocol.

1. A method for protocol translation executed on a security appliance, comprising:
receiving a first access request having a first command and a data payload, wherein the first command is formatted according to a first data transfer protocol, wherein the data payload is encrypted according to a first encryption protocol, wherein the first encryption protocol operates at a first layer of a multi-layered protocol stack; decrypting the encrypted data payload; translating the first command into a second command formatted according to a second data transfer protocol different than the first data transfer protocol; re-encrypting the decrypted data payload according to a second encryption protocol different than the first encryption protocol, wherein the second command is not encrypted, wherein the second encryption protocol operates at a second layer of the multi-layered protocol stack different from the first layer; and transmitting a second access request having the second command and the re-encrypted data payload to a server, wherein the second access request is transmitted according to the second data transfer protocol, wherein the re-encryption is transparent to the server.
