摘要： A method for validating an electronic device 2 comprises receiving attestation information provided by the electronic device 2 attesting that the electronic device 2 has received a plurality of event attestations, each event attestation providing a cryptographically authenticated attestation to the occurrence of a respective event during a lifecycle of the electronic device, and determining a validation result indicating whether the attestation information is valid. By providing separate cryptographically authenticated attestations for respective events in the lifecycle of the device, this can simplify manufacturing of the devices in a multistage manufacture process compared to an approach using a single device-specific attestation attesting that the entire process is trusted.

摘要： A machine characterization device (13) for determining one or more machine characterization parameters of a computing device (11) depending on a machine signature determined from sets of timing measurements associated with at least one machine characterization instruction executed by one or more processors (111) comprised in the computing device (11) using at least two machine configurations. A machine configuration comprises a sequence of two or more machine configuration instructions defining an order of execution of one or more instructions by the one or more processors (111).

摘要： Systems and methods for creating fingerprints for encryption devices are described herein. In various embodiments, the system includes an encryption device operatively connected to a device management system. According to a particular embodiments, the device management system: 1) receives a first payload from the encryption device, the first payload including data in a particular format; 2) creates a fingerprint for the encryption device, the fingerprint including a section format for each of one or more distinct sections of the particular format; 3) storing a record of the fingerprint for the encryption device and the unique identifier at the at least one database; and 4) comparing a format of each subsequent payload received from the encryption device to the fingerprint for the device to determine whether the device has been compromised.

摘要： An integrated circuit and a method of configuring a plurality of integrated circuits are disclosed. Each integrated circuit comprises a cryptographic key specific to it. Each integrated circuit comprises a cryptographic key specific to it. Each cryptographic key can be generated on the respective integrated circuit using a physical unclonable function and data associated with the cryptographic key, e.g. a configuration message comprising instructions for generating the cryptographic key using the physical unclonable function. The cryptographic key specific to the integrated circuit is not stored on the integrated circuit. Each of the plurality of integrated circuits are configured using a data file that is encrypted with the respective cryptographic key specific to the integrated circuit, circuit.

摘要： Disclosed are systems and methods of identifying a new device during a user's interaction with online services, such as banking services. In one example, a method is provided comprising collecting fingerprint for a device associated with a user, isolating, from the fingerprint, one or more key characteristics of the device which affect device security, performing clustering of previously known devices used by the user based on the one or more key characteristics, computing a difference between the one or more key characteristics of the device and one or more key characteristics of one or more devices which the user previously used to access an online service, wherein the one or more devices are from among the clustering of previously known devices and determining that the device is a new device used by the user when the difference exceeds a threshold value.
