Abstract
A portable media system for a host computer system, and method of operation thereof, that includes: a controller in the portable media system for communicating clear information between the portable media system and the host computer system; and an encryption system in the portable media system for providing an encryption algorithm for the controller to decrypt cipher information for the host computer system.
Claims19
A method comprising:
- generating, by a portable media system, an internal encryption key inside of the portable media system for encrypting clear information and decrypting cipher information, the portable media system being configured to store the cipher information, the portable media system configured to store the cipher information, the portable media system configured to receive and send the clear information, the portable media system configured to receive and send the cipher information;
- storing the internal encryption key inside the portable media system, wherein the internal encryption key is not visible outside the portable media system;
- receiving, by the portable media system from a host computer system, a command indicating a selection of the clear information or the cipher information to be transmitted;
- retrieving the cipher information from a memory of the portable media system based on the command;
- decrypting the cipher information when the command indicates the selection of clear information;
- and
- transmitting the cipher information or the clear information from the portable media system to the host computer system based on the command, wherein the encryption and decryption is performed by the portable media system away from the host computer system using the internal encryption key.

A portable media system comprising:
- a memory for storing cipher information;
- a controller configured for:
- generating an internal encryption key inside the portable media system for encrypting information in the portable media system;
- storing the internal encryption key in the controller, wherein the internal encryption key is not visible outside the portable media system;
- and
- receiving, by the portable media system after generating the internal encryption key, a command indicating a selection of clear information or cipher information to be transmitted to a host computer system;
- and
- an encryption system for:
- retrieving the cipher information from the memory based on the command;
- decrypting the cipher information when the command indicates the selection of clear information;
- and
- transmitting the clear information or the cipher information from the portable media system to the host computer system based on the command, wherein the encryption and decryption is performed by the portable media system away from the host computer system.

A method comprising:
- generating, by a portable media system, an internal encryption key inside of the portable media system for encrypting information in clear form and decrypting information in cipher form, the portable media system being configured to store the information in cipher form, the portable media system configured to receive and send the information in cipher form, the portable media system being to generate the information in cipher form with the internal encryption key when a host computer system transmits the information in clear form;
- storing the internal encryption key inside the portable media system, wherein the internal encryption key is not visible outside the portable media system;
- encrypting, by the portable media system, information received by the portable media system utilizing the internal encryption key stored in the portable media system;
- storing the encrypted information in the portable media system;
- receiving a command including a selection of the information in clear form or in cipher form to be transmitted to a repository;
- and
- transmitting the information in clear form or in cipher form from the portable media system to the host computer system connected to the portable media system, the host computer system configured for transmitting the information in clear form or in cipher form to the repository for storage in the repository, wherein the encryption and decryption of the information is performed by the portable media system away from the host computer system and away from the repository.
