Abstract: An apparatus includes an interface for an electronic device and a baseboard management controller (BMC). The BMC includes circuitry configured to, through the interface, monitor current usage by the electronic device, determine a security status of the electronic device based upon the current usage, and take a corrective action based upon the security status.

Abstract: The method for securely processing digital information, has the following steps, performed by a secure element (100) having a secure processor (102): - loading (S10) the digital information (Si'') from an external memory (200) into the secure element (100); - segmenting (S13) the digital information (Si) into words of digital information (Wij,k), generating error-detection codes (EDCj,k) or error- correction codes (ECCi,k) from said words of digital information and associating said error-detection codes with the corresponding words; - transferring (S15) the words of digital information (Wij,k) and the associated error-detection codes (EDCj,k) or error-correction codes (ECCi,k) to the secure processor (102); - in the secure processor (102), verifying (S16) the words of digital information (Wij,k) based on the associated error-detection codes (EDCj,k) or error-correction codes (ECCi,k) before processing the digital information contained in said words (Wij,k).

Abstract: The present invention provides a Method (100) for intrusion detection to detect malicious insider threat activities within a network (201) of multiple interconnected computerized user profiles (203), comprising the following method steps: - Training (101) a Neural Network on multiple sets of user profile data for multiple user profiles (203) and on multiple sets of activity data (211) of the multiple user profiles (203) of the network (201), such that the Neural Network is capable of predicting for future dates activities for multiple user profiles (203), - Applying (103) the trained Neural Network on the set of further user profile data of the further user profile, - Predicting (105) an activity of the further user profile (204) based on the multiple sets of activity data (211) by the trained Neural Network, - Observing (107) activity of the further user profile (204), - Applying (109) the trained Neural Network on the observed activity, and - Detecting (111) malicious activity for the further user profile (204) by the trained Neural Network, if the observed activity deviates from the predicted activity. The current invention further provides a system (200) configured to execute the method (100)

Abstract: A computing system provides clock readings from an untrusted code to trusted code, where the trusted code is executed in a secure enclave and the untrusted code is executed outside the secure enclave. The computing system allocates a pointer to shared memory that is shared between the untrusted code and the trusted code. Under control of the untrusted code, the computing system periodically writes a clock reading to the shared memory. Under control of the trusted code, the computing system reads the clock reading stored in shared memory. The untrusted code cannot determine when the trusted code reads a clock reading.

Abstract: Masking a data rate of transmitted data is disclosed. As data is transmitted from a production site to a secondary site, the data rate is masked. Masking the data rate can include transmitting at a fixed rate, a random rate, or an adaptive rate. Each mode of data transmission masks or obscures the actual data rate and thus prevents others from gaining information about the data or the data owner from the data transfer rate.
