  • Publication number: 20190109869
    Abstract: The present disclosure describes systems and methods for detection and mitigation of malicious encryption. A security agent on an infected computing device may monitor data writes to disk, memory, or network transmission buffers for strings that may represent encryption keys or moduli. The security agent may apply one or more techniques to decode and parse the string to either identify or extract the keys, or rule out the string as containing an encryption key or modulus. If a key is identified, or its presence cannot be excluded, then the security agent may generate an alert and take mitigation actions.

  • Patent number: 9923718
    Abstract: In one aspect, a method comprises the steps of deriving a base point on an elliptic curve in a first processing device, generating authentication information in the first processing device utilizing the base point and a private key of the first processing device, and transmitting the authentication information from the first processing device to a second processing device. The base point on the elliptic curve may be derived, for example, by applying a one-way function to a current time value, or by computation based on a message to be signed.

  • Patent number: 9280871
    Abstract: Techniques for providing authentication functionality in a gaming system are disclosed. In one aspect, a gaming system is configured such that, at a given point during a current session of a game in progress that involves at least one user previously granted access by the system to participate in the current session, information available from an authentication token associated with the user is obtained prior to allowing the user to take a particular action in the game. A determination is made as to whether or not the user will be allowed to take the particular action in the game, based on the obtained information. The obtained information may comprise, for example, at least a portion of a one-time password generated by a hardware or software authentication token.

  • Patent number: 9137012
    Abstract: A first processing device, which may be, for example, a wireless authentication token or an RFID tag, transmits information in a wireless network in a manner that emulates standard communications of an access point of the wireless network, although the first processing device is not configured to operate as an actual access point of the wireless network. A second processing device, which may be, for example, a computer or other station of the wireless network, receives the transmitted information and is able to determine therefrom that the information originates from an emulated access point rather than an actual access point. The second processing device responds to this condition by utilizing the transmitted information in a manner distinct from its utilization of similar information received from the actual access point of the wireless network.

  • Patent number: 8607045
    Abstract: In a system comprising a transient storage device (TSD) or other type of peripheral configured for communication with a host device, a first one-time password or other type of code is generated in the peripheral and transmitted to the host device. The first code is presented by the host device to an authentication server for authentication. The host device receives a second one-time password or other type of code from the authentication server and transmits it to the peripheral for authentication.

  • Patent number: 8515070
    Abstract: Enhanced security is provided in a system comprising a medical device and a monitoring device. The medical device is configured for implantation into a living organism, and comprises processing circuitry and an interface for communicating with the monitoring device. Access to the medical device by the monitoring device is controlled based on measurement of one or more physiological values of the living organism by at least one of the two devices. In an illustrative embodiment, the medical device and the monitoring device are configured to include respective physiological value sensors for measuring respective dynamic physiological values of the living organism. The medical device is further configured to determine if the dynamic physiological values are sufficiently similar to one another and to grant or deny the monitoring device access to the medical device based on the determination.

  • Patent number: 8495372
    Abstract: In one aspect, a first processing device, which may be an authentication token, establishes a shared key through a pairing protocol carried out between the first processing device and a second processing device. The pairing protocol also involves communication between the second processing device and an authentication server. As part of the pairing protocol, the first processing device sends identifying information to the second processing device, and the second processing device utilizes the identifying information to obtain the shared key from the authentication server. The first processing device encrypts authentication information utilizing the shared key, and transmits the encrypted authentication information from the first processing device to the second processing device. The second processing device utilizes the shared key to decrypt the encrypted authentication information.

  • Patent number: 8378786
    Abstract: Enhanced security is provided in an RFID system comprising a plurality of RFID devices and at least one reader which communicates with one or more of the devices. In one aspect of the invention, a first command is transmitted from the reader to write a first data unit to a memory of given one of the RFID devices. A reply is received in the reader from the given RFID device indicating that a second data unit determined based on contents of the first data unit is available in the memory to be accessed by the reader. A second command is transmitted from the reader to the given RFID device to allow the reader to read the memory to thereby obtain the second data unit. The first and second data units comprise information exchanged as part of a cryptographic protocol carried out between the reader and the given RFID device. In an illustrative embodiment, the cryptographic protocol may comprise a challenge-response authentication protocol.

  • Patent number: 7920050
    Abstract: A proxy device is disclosed for use in an RFID system comprising a plurality of RFID devices and at least one reader which communicates with the proxy device and one or more of the RFID devices. The proxy device acquires information characterizing at least a given one of the RFID devices, controls the given RFID device so as to at least partially prevent the given RFID device from being read by the reader, and communicates with the reader in a manner which simulates the given RFID device. This advantageously allows the proxy device to implement privacy policies of arbitrary sophistication on behalf of the given RFID device. The proxy device subsequently releases control of the given RFID device so as to permit the given RFID device to again be read by the reader.
