In described examples, a processor system includes a mailbox, a hardware security functional block (HSFB, also called a trusted agent herein), a processor, and a processor firewall. The HSFB includes a database configured to store at least one software context access rule. The processor executes multiple software contexts. The HSFB approves or denies an access request received from a debugging tool, via the mailbox, in response to the database and a software context identification (ID) included in the access request. The HSFB sends a message to the processor firewall indicating whether the access request is approved. The processor firewall determines whether to pass instructions to the processor for execution with respect to the identified software context in response to the message.

A method, system and device are disclosed. A premises device comprising a first operating system and a second operating system is described. The premises device comprises processing circuitry configured to establish a chain of trust at least between the first operating system and at least one software application associated with the second operating system. The processing circuitry is further configured to perform at least one action based at least in part on the established chain of trust.

A method for integrating a further bus subscriber into a bus system, and a bus system, having a master module and subscribers disposed in series, includes the temporally consecutive method steps: in a first method step, the further bus subscriber transmits a data packet to the master module in order to log in to the master module, in a second method step, a bus subscriber disposed between the further bus subscriber and the master module stops the data packet and checks whether the bus system has already received a release, in a third method step, the first bus subscriber forwards the data packet to the master module if the bus system has not yet received a release, or in a third, in particular an alternative, method step, if the bus system has already received a release, the bus subscriber stores the data packet and waits until the release of the bus system is revoked and after the release has been revoked, forwards the stored data packet to the master module.

The present invention provides various aspects for processing multiple types of substrates within cleanspace fabricators or for processing multiple or single types of substrates in multiple types of cleanspace environments particularly to form hardware based encryption devices and hardware based encryption equipped communication devices and multi-chip modules such as chiplets. In some embodiments, a collocated composite cleanspace fabricator may be capable of processing semiconductor devices into integrated circuits and then performing assembly operations to result in product in packaged form. Customized smart devices, smart phones and touchscreen devices may be fabricated in examples of a cleanspace fabricator. The assembly processing may include steps to form hardware based encryption.

An example operation includes one or more of encrypting, by a transport, received data based on a first biometric associated with an occupant, unencrypting, by the transport, the encrypted data, based on a verification of a second biometric, wherein the second biometric is a continuum of the first biometric, and providing, by the transport, the unencrypted data to the occupant.

A monitoring method and system for secure conveying are provided. In a process of conveying a confidential document or item by a secure conveying device, a conveying path of the secure conveying device can be monitored in real time, and a distance between the secure conveying device and an accompanying person can also be monitored in real time. In a case where the secure conveying device neither deviates from a predetermined path nor is separated from the accompanying person, safe opening of the secure conveying device is ensured through a combination of open time, an open position, and open authorization information, thereby ensuring security of the confidential document or item conveyed by the secure conveying device.

A communications device for managing an authentication event is provided, which is configured to generate location data indicative of a geolocation associated with the communications device, retrieve, from a key that is obfuscated and stored in the communications device, the key, sign the location data with the retrieved key, and transmit request data to a communications server apparatus for requesting the authentication event, the request data comprising the signed location data. A method and a communications system for managing an authentication event are also provided.

An electronic device is disclosed that comprises a substrate and an electronic circuit with a layer between them. The layer comprises an electrically insulating medium containing a spatial distribution of conductive elements. The electronic circuit comprises memory contacts arranged for electrical connection to a corresponding contact on the substrate when at least one of the conductive element forms a connection between a memory contact and the corresponding contact but for electrical insulation from the corresponding contact when no conductive elements forms such a connection. A selection of the memory contacts, that is at least partially random, is thus electrically connected to the corresponding contact on the substrate. Memory circuitry is configured to store a representation of a respective electrical connection status of the memory contacts.

A data providing apparatus obtains first privacy data and second privacy data, encrypts the first privacy data by using an encryption algorithm to obtain a ciphertext of the first privacy data, and sends the ciphertext of the first privacy data and the second privacy data to a data processing apparatus. The data processing apparatus inputs the ciphertext of the first privacy data and the second privacy data into a ciphertext computation function to obtain a ciphertext of a data processing result. In this way, the first privacy data is used in computation in a ciphertext form, thereby ensuring security. In addition, the second privacy data is used in computation in a plaintext form, thereby reducing ciphertext input for the ciphertext computation function.

A semiconductor device includes a first control unit, a second control unit, a random number generator, a first memory in which random numbers generated by the random number generator are stored, an encryption engine configured to perform encryption and decryption processes by using the random numbers stored in the first memory, and a second memory in which information related to random number generation is stored. The second control unit is configured to generate the random numbers by the random number generator based on the information related to random number generation.
