<p>In an embodiment, a method of transmitting data from a user terminal to a decryption component over a communication network in a limited connectivity environment includes at the user terminal, receiving data from a user at the user terminal. If it is determined that the data is sensitive data, the sensitive data is encrypted using a secure encryption key. A packet is generated based on tunnelling protocol, the packet including command data and the encrypted sensitive data. The command data includes an address of a network component, a command and a command identifier. The command identifies that the secure encryption key has been used to encrypt the sensitive data. At the network component identified in the address, the packet is received at a first port; the command is read; the packet is forwarded via a second port to the decryption component for decryption; and a response packet is forwarded, including a response and the command identifier, to the user terminal.</p> |
