A mechanism is provided in which a secure chip for performing cryptographic and / or other functions is able to securely access a separate random access memory externally disposed with respect to a secure chip boundary. Addressing of the external memory is controlled so as to define certain regions therein which receive and store only encrypted information from the chip. Other regions of the external memory are set aside for the receipt and storage of unencrypted information. Access to the external memory is provided through a controlled interface which communicates with internal chip hardware which operates to control the flow of communication between various internal components such as cryptographic engines, data processors, internal memory of both the volatile and the nonvolatile variety and an external interface which provides the only other access to the chip. The internal chip hardware with which the external memory interface communicates is implemented as a combined ASIC and programmable hardware circuit, wherein the programmable hardware circuit is also securely configurable.

A system and method are provided for securely providing configuration information, that is, programming, to programmable hardware such as a Field Programmable Gate Array (FPGA) or a Programmable Logic Device (PLD).

Additionally, the configuration information is itself provided in an encrypted form which requires recognition of the certificate of authority in order to decrypt it and to place it in storage locations within the programmable hardware. In this manner, the flexibility advantages of programmable hardware are fully met without the disadvantage of the programmable hardware being compromised by other users.

An integrated circuit chip is provided which contains one or more processors and one or more cryptographic engines. A flow control circuit having a command processor accepts requests and data via a secure external interface through which only encrypted information is passed.

In particular the flow control circuit includes a programmable hardware portion which is configurable in a secure manner to create a flexible internal chip architecture. The chip also includes a volatile memory disposed on a voltage island on which is maintained either through a battery backup or from a fixed power source (mains). The chip is thus enabled to securely perform cryptographic operations with the processors controlling the cryptographic engines through the flow control circuit.

A system and method are provided in which a third party chip vendor is enabled to securely program an electronic circuit chip supplied from a chip manufacturer.

The chip includes a processor and an associated memory which receives a version of the instructions decrypted with the chip private key and the vendor's public key. The chip also preferably includes programmable hardware which is also securely programmable by the downstream chip vendor. The chip, as processed by the chip vendor is shipped with a battery in place to provide power for maintaining data held in volatile memory portions of the chip.

An integrated circuit chip is provided which contains one or more processors and one or more cryptographic engines. A flow control circuit having a command processor accepts requests and data via a secure external interface through which only encrypted information is passed. The flow control circuit mediates decryption of this information using one or more cryptographic keys passed to the command processor. The decrypted information is stored in a preferably volatile, on-chip memory in unencrypted form. The flow control circuit is then able to accept requests which invoke the stored, decrypted instructions. More specifically, the invoked instructions are usable to control the cryptographic engines present on the chip in ways knowable only to the one who provides the encrypted instructions. In this way, many different encryption algorithms are employable in a secure fashion.

Only when a wall side and the vicinity of an obstacle are cleaned, a side brush is operated and the cleaning is carried out, and when any other place than the wall side and the vicinity of the obstacle is cleaned, the side brush is maintained in a stoppage state. When a place such as the wall side or the vicinity of the obstacle in which dust is easy to accumulate is cleaned, the side brush is operated to enhance the dust collecting property. When any other place than the wall side or the vicinity of the obstacle is cleaned, the side brush is stopped to suppress power consumption and generation of a noise. A judgment processing portion detects based on a detection signal from an obstacle detecting portion that a cleaner is approaching a wall or an obstacle. In response to such detection, the judgment processing portion instructs a travel steering portion to carry out immediate rotation and change of a travel direction, or travel along a wall side. Also, the judgment processing portion instructs a side brush driving portion to drive a side brush only in the rotation and in the wall side travel, and to stop the side brush in straight advance travel.

The primary purpose of this invention is to provide a method whereby the thickness of slag can be measured with a high degree of precision without depending on the operator. This invention uses a microwave distance meter that uses an antenna to emit and receive frequency-modulated microwaves that have a central frequency between 24 and 32 GHz and a frequency-modulation amplitude between 8 and 10 GHz. A first length of time from when the microwave distance meter emits the aforementioned microwaves to when microwaves reflected off the surface of a molten metal are received is computed, as is a second length of time from when the microwaves are emitted to when microwaves reflected off the surface of slag are received. A calculated value c(t1-t2) / 2 is computed from the first length of time t1, the second length of time t2, and the speed c of microwaves in air. A correction formula is obtained in advance from calculated-value measurement results from slag of previously-known thicknesses, and during operation, values obtained by using said correction formula to correct calculated values measured successively by the microwave distance meter are used as slag thicknesses.
