Provided are techniques for providing a home or business security system that relies upon data encryption for both communication and the storage of content. The disclosed technology incorporates all the devices necessary for a comprehensive security system, including, but not limited to, controllers, monitors, alarms and communication media. The system may include an unlimited number of devices and, further, individual devices may be added and removed as needed. Users may define and change the boundaries of a security system or, in other words, decide what devices to include or not include in such a system. A defined boundary does not need to be confined to a single location. In one embodiment, the claimed subject matter incorporates xCP based broadcast encryption technology.

Provided is a method for defining and organizing computer breakpoints for use during a debugging operation of a software application. The claimed subject matter provides flexible breakpoints that are called depending upon the condition of the corresponding call-stack or, in other words, depending upon a specific calling sequence through which the module containing the breakpoint was reached. A novel type of breakpoint is provided that, rather than causing a halt in execution of a module, changes the state of one or more other breakpoints. In an alternative embodiment, a breakpoint is provided that determines whether or not to execute based upon an examination of the call-stack.

Creating software debug breakpoints activated by specific call patterns

Provided is a method for enabling a device without a secure clock to make a determination on the expiration of encrypted content. When the device receives content, the device also receives the content provider's policy on access. This information provides an ATI in UTI units which is to be associated with the content for the purpose of managing the content's expiration. The ATI is converted to the device's DTI units and the DTI is then used to control the availability of the content for decryption and use. The claimed subject matter permits the existence of tolerance, determined by content policy, in the conversion between UTI and the DTI, as well as in the depletion of the ATI. To move or copy content which has an associated remaining ATI, the device converts the ATI into UTI units and provides converted ATI to the target device in conjunction with the associated content.
