Systems and methods for performing transport I/O

A method comprising:

• receiving, by a removable security device not operating in ISO-7816 mode, network encrypted content;
• decrypting the network encrypted content using at least one network control word to generate clear content, wherein the at least one network control word is not made accessible by the removable security device;
• encrypting, by the removable security device, the clear content using at least one local control word to generate locally encrypted content, wherein the locally encrypted content is specific to a video processing device physically coupled to the removable security device;
• and
• providing the locally encrypted content to the video processing device.

A system comprising:

• a video processing device;
• and
• a removable security device electrically coupled to the video processing device and comprising at least one processor, wherein the at least one processor performs a method comprising:
• receiving, by the removable security device when not operating in ISO-7816 mode, network encrypted content;
• decrypting the network encrypted content using at least one network control word to generate clear content, wherein the at least one network control word is not transmitted from the removable security device;
• encrypting, by the removable security device, the clear content using at least one local control word to generate locally encrypted content, wherein the locally encrypted content is specific to a video processing device physically coupled to the removable security device;
• and
• providing the locally encrypted content-to the video processing device.
