Abstract: An apparatus with an integrated circuit (IC) chip can provide protection against attacks on a read-only memory (ROM), such as a boot ROM for security circuitry. An attacker can gain control of an IC by modifying ROM contents and/or redirecting ROM reads. To combat these attacks, example implementations store encrypted ROM data in the ROM array. A ROM controller is used to cryptographically tie the address of each ROM line to the corresponding encrypted ROM datum. To access the encrypted ROM datum, cryptographic circuitry decrypts the encrypted ROM datum using a key that is generated based on the corresponding ROM address. As part of an integrity checking procedure, a digest can be computed based on the encrypted ROM data. To further thwart would-be attacks, the ROM address can be adjusted (e.g., scrambled) before the controller uses the adjusted address to read encrypted data from the ROM array.

Abstract: Techniques and devices for spatial averaging of transmission power to reduce power cutbacks are described. The techniques of spatial averaging may enable separate determinations of transmit power capacities for each antenna of a computing device if each antenna is spaced apart from a neighboring antenna by a minimum distance. The transmit power capacities may be based on transmit power limits and, in general, may be determined independently from, or with reduced dependence on, a transmit power of another antenna. These separate determinations may allow for spatial averaging of transmission power of a device to improve antenna-switching decisions and reduce a dependence upon power cutbacks. When power cutbacks are unavoidable, the separate determinations may additionally improve antenna-switching decisions at cutback powers to optimize the transmission power of the device.
