Abstract
A device may not trust another device with which it is in communication. To establish trust, a first device may send a second device an indication of signed code that is stored in a protected memory of the first device. Based on determining that the first device is a trusted device, the second device may send the first device an encrypted content asset, a decryption key associated with the content asset, and/or an encryption key associated with the content asset.
