The invention comprises a mobile device with two circuit boards and certain shared resources, in order to provide the security of physically separate devices, yet do so in a single device using shared resources that do not affect security. Specifically, the invention has two boards connected via input/output switch, each having its own System-on-a-Chip (SoC), Memory (RAM), Storage and Radio Module (SIM(s)/Bluetooth/Wi-Fi), and may include one or more SIM cards. Touchscreen, battery, physical buttons and other peripherals are shared between boards. Each shared peripheral hardware module will be used by a single board only (the active in-use board being the “Foreground Board”); another board (the inactive “Background Board”) uses an emulated version of the same hardware module. At any moment, a user can switch between Boards and the Background Board becomes the active Foreground Board and vice versa.

Systems and methods for “machine-to-machine” (M2M) communications between modules, servers, and an application using public key infrastructure (PKI)
11606204 · 2023-03-14 · ·

Methods and systems are provided for supporting efficient and secure “Machine-to-Machine” (M2M) communications using a module, a server, and an application. A module can communicate with the server by accessing the Internet, and the module can include a sensor and/or an actuator. The module, server, and application can utilize public key infrastructure (PKI) such as public keys and private keys. The module can internally derive pairs of private/public keys using cryptographic algorithms and a first set of parameters. A server can authenticate the submission of derived public keys and an associated module identity. The server can use a first server private key and a second set of parameters to (i) send module data to the application and (ii) receive module instructions from the application. The server can use a second server private key and the first set of parameters to communicate with the module.

System and method of detecting hidden processes by analyzing packet flows

A method includes capturing first data associated with a first packet flow originating from a first host using a first capture agent deployed at the first host to yield first flow data, capturing second data associated with a second packet flow originating from the first host from a second capture agent deployed outside of the first host to yield second flow data and comparing the first flow data and the second flow data to yield a difference. When the difference is above a threshold value, the method includes determining that a hidden process exists and corrective action can be taken.

STATEFUL SERVICES ON STATELESS CLUSTERED EDGE

In order to enable dynamic scaling of network services at the edge, novel systems and methods are provided to enable addition of add new nodes or removal of existing nodes while retaining the affinity of the flows through the stateful services. The methods provide a cluster of network nodes that can be dynamically resized to handle and process network traffic that utilizes stateful network services. The existing traffic flows through the edge continue to function during and after the changes to membership of the cluster. All nodes in the cluster operate in active-active mode, i.e., they are receiving and processing traffic flows, thereby maximizing the utilization of the available processing power.

TECHNOLOGIES FOR MANAGING COMPROMISED SENSORS IN VIRTUALIZED ENVIRONMENTS

Systems, methods, and computer-readable media for managing compromised sensors in multi-tiered virtualized environments. In some embodiments, a system can receive, from a first capturing agent deployed in a virtualization layer of a first device, data reports generated based on traffic captured by the first capturing agent. The system can also receive, from a second capturing agent deployed in a hardware layer of a second device, data reports generated based on traffic captured by the second capturing agent. Based on the data reports, the system can determine characteristics of the traffic captured by the first capturing agent and the second capturing agent. The system can then compare the characteristics to determine a multi-layer difference in traffic characteristics. Based on the multi-layer difference in traffic characteristics, the system can determine that the first capturing agent or the second capturing agent is in a faulty state.

A microprocessor includes a cryptographic engine and a controller. The cryptographic engine is configured to execute a cryptographic algorithm. The controller is connected to the cryptographic engine. The controller is configured to receive an access request from a first execution environment. The access request accesses the cryptographic engine to execute the cryptographic algorithm. The access request includes at least identification information. The identification information indicates that the access request is from the first execution environment. The first execution environment is an execution environment of a number N execution environments. N is an integer greater than or equal to 1. The controller is further configured to, based on the identification information, instruct the cryptographic engine to execute the cryptographic algorithm that needs to be executed required by the access request.
