Portable device using a smart card to receive and decrypt digital data

   
   

A system and method for securely downloading digital music data includes a portable handheld device having a detachable smart card for decrypting encrypted music as it is played thereby allowing the portable device to receive and play encrypted music files. The smart card includes both a digital decryption key and hardware that decrypt the encrypted music using the key. The portable handheld device is configured to connect to a remote server, using the decryption key to establish a secure data communications channel, in order to receive the encrypted music files from the remote server. In an alternative system, a personal computer (PC) that is configured to connect to the smart card allows the PC to download and play the encrypted music. In another aspect of the system and method, the smart card provides the remote server with information that is used to pay for the downloaded digital music data. In one embodiment, the smart card has a stored monetary value that is read and modified by the remote server. Alternatively, data stored on the smart card, such as personal identification information, can be used to bill the end user for the digital data. In another embodiment of the invention, the method includes accessing digital data stored at one or more servers using an access key stored on the smart card. In this embodiment, the method includes reading access keys contained on the smart card and accessing the designated server using the access keys.
