  • Terminal identity protection method in a communication system
    Patent number: 11336437
    Abstract: A method for determining a terminal ID from a message received from a terminal in a communication system avoids sending the terminal ID in the clear. In this system each terminal ID has an associated encryption key. A transmitted message comprises at least a Message Authentication Code (MAC), a n-bit hash, and encrypted message text. At least the terminal key and a nonce is used to generate the MAC, and neither the terminal ID or the terminal key are included in the transmitted message. An authentication broker stores the set of all (terminal ID, terminal key) pairs for the plurality of terminals in the communication system. The set of all terminal keys is grouped into at least two partitions, and on receipt of a message the authentication broker identifies the partition that includes the terminal key of the terminal that transmitted the received message using the n-bit hash (the search partition).

  • System and method for malware detection
    Patent number: 11316878
    Abstract: Systems and methods for malware detection techniques, which detect malware by identifying the C&C communication between the malware and the remote host. In particular, the disclosed techniques distinguish between request-response transactions that carry C&C communication and request-response transactions of innocent traffic. Individual request-response transactions may be analyzed rather than entire flows, and fine-granularity features examined within the transactions. As such, these methods and systems are highly effective in distinguishing between malware C&C communication and innocent traffic, i.e., in detecting malware with high detection probability and few false alarms.

  • Secure packet modification
    Patent number: 11245677
    Abstract: In various implementations, a network device receives a packet from a content producer. The packet includes data and further includes a signature generated by the content producer, based on the data, using a private key of the content producer. The network device modifies the packet without affecting the signature and forwards the modified packet toward a user device. The network device also sends the user device a manifest specifying how the packet was modified. The user device receives the packet and manifest, restores the packet's original data based on the manifest, and verifies the original data using the signature and a public key corresponding to the private key of the content producer. In response to verification of the original data, an application on the user device is allowed to use the data.
