  • Patent number: 11263353
    Abstract: This disclosure describes systems on a chip (SOCs) that prevent side channel attacks (SCAs). An example SoC of this disclosure includes an engine configured to encrypt transmission (Tx) channel data using an encryption operation set configured with a first polynomial, and to decrypt encrypted received (Rx) channel data using a decryption operation set configured with a second polynomial different from the first polynomial. The SoC further includes a security processor configured to multiplex the encryption operation set against the decryption operation set with a varied sequence of selection inputs on a round-by-round basis to generate a mixed sequence of encryption rounds and decryption rounds, and to control the engine to encrypt the Tx channel data and decrypt the encrypted Rx channel data in a combined datapath according to the mixed sequence of encryption rounds and decryption rounds.

  • Patent number: 11256814
    Abstract: Using a processor and a memory of a testing system, a set of vulnerability testing instructions is executed relative to an application, causing an output of a set of vulnerabilities from the testing system. By executing a probability model, a first probability of adverse impact corresponding to a first vulnerability in the set of vulnerabilities is computed. The first vulnerability and the first probability of adverse impact are added to a vulnerability repository. Using the first probability of adverse impact and a second probability of adverse impact, a first cumulative probability of adverse impact is calculated. Using the first cumulative probability and a first level of organizational impact corresponding to the application, a first risk category is assigned to the application. Responsive to the first risk category being lower than a second risk category, a system management application is caused to install the application in the computer system.

  • Patent number: 11240116
    Abstract: A spacecraft network management system includes five functional entities, namely, attendant, accessor, collector, logic, and logic watchdog in a distributed architecture configured with both in-band and out-of-band data paths. Management data is structured so that it can travel over either in-band or out-of-band and be identified as such; user data travels over in-band paths. These five entities are distributed over the units of the design and then a modified set of otherwise standard elements are assigned to each entity depending on the nature of its function. These elements include managers, management agents, device agents, device management information base, and manager management information base that enable the entities to perform their respective functions.

  • Patent number: 11240659
    Abstract: Various embodiments are generally directed to techniques for providing improved privacy protection against vehicle tracking for connected vehicles of a vehicular network. For example, at least one road side unit may: identify a set of vehicles that require pseudonym changes and send an invitation for a pseudonym change event to each of the vehicles, determine at least a total number of the acceptances, determine whether the total number meets or exceeds a predetermined threshold number, send acknowledgement messages to the accepting vehicles if the threshold number is met, and form a vehicle group to coordinate the pseudonym change event during a privacy period. During the privacy period, the RSU and the vehicles may communicate with each other in a confidential and private manner via key-session-based unicast transmission, and coordinate transmission power and vehicle trajectory adjustments to maximize the benefits for safety and obfuscation for privacy.

  • Patent number: 11218296
    Abstract: A data storage system allows data to be encrypted and de-duplicated at the same system. By way of example, a server of the data storage system may request a client device which intends to upload a data block to transmit a first fingerprint of the data block to the server. The first fingerprint may be derived from the plaintext of the data block. The server may apply a one-way function to the first fingerprint to generate an encryption key and transmit the encryption key to the client device. The client device uses the encryption key to encrypt the data block and generates a second fingerprint which is derived from the ciphertext of the data block. The server uses both the first fingerprint and the second fingerprint to verify the data block and the legitimacy of the client attempting to upload the data block.

  • Patent number: 11205013
    Abstract: Technologies are disclosed for a computing system that allows users to control the disclosure of their identities during communication sessions. Users can control the disclosure of their identities with respect to certain types of shared content. In one mode of operation, a user can share content anonymously. In another mode of operation, identity may be revealed when certain conditions are met or revealed to only certain other users. For example, the identity of a user who shared a comment anonymously may be revealed if multiple other users agree with that comment. In another mode of operation, the user's identity is revealed to all other users such as in a live video stream. The computing system can control display of users' identities based on user instructions or based on triggering conditions. A user interface (UI) can show content items that identify a user together with content items that are shared anonymously.

  • Patent number: 11165557
    Abstract: In general, this disclosure describes encryption engines that shuffle data segments during decryption. By shuffling the data and using the resulting random permutation for decryption, the engines of this disclosure obfuscate hardware performance information that attackers might access and use in a side channel attack. In one example, an apparatus includes a decryption engine configured to select, for each round of multiple rounds for decrypting the block of encrypted data, a permutation of inputs to the decryption engine from multiple permutations of the inputs. The inputs include encrypted data segments of the block of encrypted data and an inverse cipher key segment, and the selected permutation of the inputs is different for at least two of the rounds. The decryption engine is further configured to iteratively compute a decrypted data segment across the plurality of rounds based on the respective selected permutation of the inputs for each round.

  • Patent number: 11157659
    Abstract: A method for executing a polymorphic machine code, wherein: for each branching address at which a base block of a flow of generated instructions starts, the microprocessor automatically adds, in the generated flow of instructions, a renewal instruction suitable, when it is executed, for triggering the renewal of an initialization vector of a module for decryption by flow with a specific value associated with this branching address, then a flow encryption module encrypts the flow of instructions as it is generated and, during this encryption, each base block is encrypted using a specific value associated with the branching address at which it starts. Only the instruction flow encrypted in this way is recorded in the main memory. During execution of the encrypted instruction flow, the added renewal instructions are executed as they are encountered.
