  • Patent number: 11144632
    Abstract: Some embodiments described herein include a method to validate supply chains for electronic devices using side-channel information in a signature analysis. The method includes sending, to a target device, a first signal associated with a set of codes to be executed by the target device, and then receiving first side-channel information associated with the target device in response to the target device executing the set of codes. The method also includes determining second side-channel information associated with a simulated device in response to the set of codes. The method further includes comparing a discriminatory feature of the first side-channel information with a discriminatory feature of the second side-channel information to determine a characteristic of the target device based on a pre-determined characteristic of the simulated device. Finally, the method includes sending, to a user interface, a second signal associated with the characteristic of the target device.

  • Patent number: 11139966
    Abstract: Techniques are provided for security code for integration with an application. A first request associated with a request by an application to an application server is received. The application includes security code that performs a set of one or more operations on one or more input parameters. The application is provided one or more parameter values, wherein the security code generates a secret cryptographic key based on the one or more parameter values. A security key is received that includes encrypted client data collected at the client device that is encrypted using the secret cryptographic key. The secret cryptographic key is generated based on the one or more parameter values and knowledge of the set of one or more operations. It is determined that the decrypted client data matches a pattern of data associated with malware. The application server is prevented from processing a second request.

  • Patent number: 11113395
    Abstract: According to some embodiments, a plurality of monitoring nodes each generate a series of current monitoring node values over time that represent a current operation of a wind turbine. An abnormality detection computer platform may receive the series of current monitoring node values and generate a set of current feature vectors. The abnormality detection computer platform may also access an abnormality detection model having a plurality of decision boundaries created using wind information (e.g., wind speed and/or acceleration) along with at least one of a set of normal feature vectors and a set of abnormal feature vectors. The abnormality detection computer platform may then select one of the decision boundaries based on current wind information associated with the wind turbine and execute the abnormality detection model and transmit an abnormality alert signal based on the set of current feature vectors and the selected decision boundary.

  • Patent number: 11102012
    Abstract: A method for digital signing of a document using a predetermined secret key. An initial internal state is determined by application to a condensate of the document of a first white box implementation of generation of a main nonce; then a modular sum of the main nonce and of a predetermined constant. The method also determines a first internal state by application to the initial internal state of a first modular arithmetic operation, then of a modular product with exponentiation of the predetermined constant. The method then determines a second internal state by application to said condensate of a second white box implementation of generation of the main nonce; and a second modular arithmetic operation function of the first internal state, of the main signature nonce and of the secret key. It then generates a digital signature of the document from the first internal state and the second internal state.

  • Patent number: 11093022
    Abstract: Systems and methods are provided for authenticating an account via a hands-free gesture, such as a tap, pattern of taps, or other physical gesture not requiring a user to hold a computing device. A user can initiate a transaction to purchase an item by interacting with a first computing device (e.g., electronic kiosk, point-of-sale terminal, automated checkout device, etc.). The first computing device can receive a request from the user to purchase the item. In response, the first computing device can broadcast an authentication request. The user can perform the hands-free gesture for detection by a second computing device (e.g., the user's mobile device). The second computing device can transmit information associated with the hands-free gesture in response to the authentication request. The first computing device can authenticate the user based on the information associated with the hands-free gesture.

  • Patent number: 11025420
    Abstract: Secure operations can be performed using security module instances offered as a web service through a resource provider environment. State data and cryptographic material can be loaded and unloaded from the instance as needed, such that the instance can be reused for operations of different customers. The material and data can be stored as a bundle encrypted using a key specific to the hardware security module and a key specific to the resource provider, such that the bundle can only be decrypted in an instance of that type of security module from the associated manufacturer and operated by that particular resource provider. The customer is then only responsible for the allocation of that instance during the respective cryptographic operation(s).

  • Patent number: 10984114
    Abstract: A document processing method and apparatus are disclosed in embodiments of the present application. The method includes: obtaining a target geographic location where the first electronic device is currently located, when a predetermined operation for a document is detected; determining whether the target geographic location matches a target password that is used to encrypt the document in advance; and if so, allowing the predetermined operation to be performed on the document; and if not, preventing the predetermined operation from being performed on the document. The apparatus includes an obtaining module, a determining module, and a decision module. In the embodiment of the present application, the document is encrypted and decrypted by using a target password generated based on a geographic location, which ensures the security of password transmission, and improves the security of the use of the document and the convenience of authorization and decryption.

  • Patent number: 10924283
    Abstract: Techniques for use in generating a dynamically-changing IoT device identity with robust blockchain validation are provided. When entering a communication network, an IoT device performs a procedure for registration. The procedure includes communicating, in a transaction, data associated with the IoT device to a network device (e.g. a fog router). The data includes, amongst other data items, an identity for addressing communications to and from the IoT device. A transaction number associated with the transaction is received based on a blockchain registration of the transaction. An updated identity of the IoT device is then derived based on the transaction number. In one example, the updated identity of the IoT device may be derived by combining a static address of the IoT device and the transaction number. The steps may be repeated by the device for each one of a plurality of network registrations.
