Abstract
Systems and methods are for content security may comprise transmitting a request for authorization to access secured content. A content key for the secured content may be received and stored to a restricted region of a memory. A device security module may have access to the restricted region and may decrypt, based on satisfaction of a use condition and using the content key, the secured content. An encryption key associated with a secure media system authorized to access the secured content may be received. The device security module may encrypt, using the encryption key, the secured content and route the secured content to the secure media system.
Claims27
A method comprising:
- receiving, by a computing device and based on a request for authorization for a first secure media system to access secured content, a key container associated with the secured content, wherein the key container comprises an indication of a permission for the computing device to access the secured content;
- decrypting, by a device security module of the computing device and based on the indication of the permission, the secured content using a content key, wherein the content key is stored at the device security module;
- encrypting, by the device security module and using an encryption key associated with a second secure media system, the secured content;
- and
- routing, by the device security module and to the second secure media system, the secured content.
A system comprising:
- an authorization device;
- and
- a computing device configured to:
- receive, from the authorization device and based on a request for authorization for a first secure media system associated with the computing device to access secured content, a key container associated with the secured content, wherein the key container comprises an indication of a permission to access the secured content;
- decrypt, by a device security module of the computing device and based on the indication of the permission, the secured content using a content key, wherein the content key is stored at the device security module;
- encrypt, by the device security module and using an encryption key associated with a second secure media system, the secured content;
- and
- route, by the device security module and to the second secure media system, the secured content.
A non-transitory computer-readable medium storing instructions that, when executed, cause:
- receiving, by a computing device and based on a request for authorization for a first secure media system to access secured content, a key container associated with the secured content, wherein the key container comprises an indication of a permission for the computing device to access the secured content;
- decrypting, by a device security module of the computing device and based on the indication of the permission, the secured content using a content key, wherein the content key is stored at the device security module;
- encrypting, by the device security module and using an encryption key associated with a second secure media system, the secured content;
- and
- routing, by the device security module and to the second secure media system, the secured content.
A device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the device to:
- receive, based on a request for authorization for a first secure media system associated with the device to access secured content, a key container associated with the secured content, wherein the key container comprises an indication of a permission to access the secured content;
- decrypt, by a device security module of the device and based on the indication of the permission, the secured content using a content key, wherein the content key is stored at the device security module;
- encrypt, by the device security module and using an encryption key associated with a second secure media system, the secured content;
- and
- route, by the device security module and to the second secure media system, the secured content.
