  • Patent number: 10680892
    Abstract: Aspects of an embodiment of the invention disclose a method, computer program product, and system for managing the energy efficiency of servers providing multi-class computing services with Quality of Service (QoS) assurance. Computing resources are clustered into at least three groups, where each group has a separate power management policy (PMP). A plurality of requests are received from a plurality of devices, and are sorted into at least three service classes based on the requests' QoS criteria. Each request is assigned to one of at least three service queues based on the request's service class, and each service group is processed by a group of computing resources. The power management policies are configured such that each group of computing resources may service requests at an energy efficient point while meeting the QoS criteria of the service class.

  • Publication number: 20190342327
    Abstract: A method and technique for protecting against denial of service attacks includes maintaining a session count indicating a quantity of active client sessions a server is maintaining and a session threshold specifying a maximum quantity of concurrent client sessions the server can maintain. Responsive to receiving a request from a client, a request count maintained by the server is verified to be less than the session threshold and, if so, a challenge message is sent to the client and the request count is incremented. Responsive to receiving a response message to the challenge message from the client, the response message is verified, a session with the client is established, and the session count is incremented. Responsive to terminating the session with the client, the session count and the request count are decremented.

  • Patent number: 10333970
    Abstract: A method and technique for protecting against denial of service attacks includes maintaining a window over a sequence number space that includes sequence numbers that are sequentially assigned to challenge messages where the window has a leading edge and a trailing edge. Responsive to receiving a request from a client, the leading edge of the window is advanced and a leading edge sequence number is selected as a challenge sequence number. A challenge message including the challenge sequence number is sent to a client. Responsive to receiving a response message from the client, it is verified that a challenge sequence number included with the response message is within the window and does not correspond to a marked sequence number within the window.

  • Patent number: 10129292
    Abstract: The present invention provides for protecting against denial of service attacks. A request is sent by a client, the request comprises client indicia. The request is received at a server. A request count is incremented by the server. A sequence number is assigned as a function of the client indicia. A problem is selected by the server. The problem is sent by the server to the client. A solution to the problem is sent to the server. It is determined if the solution by client is correct. If the solution is correct, a session is performed. If the solution is not correct, the request is discarded. This can substantially decrease the amount of attacks performed by a rogue client, as the session set-up time can be substantial.

  • Patent number: 8677136
    Abstract: The present invention provides for authenticating a message. A security function is performed upon the message. The message is sent to a target. The output of the security function is sent to the target. At least one publicly known constant is sent to the target. The received message is authenticated as a function of at least a shared key, the received publicly known constants, the security function, the received message, and the output of the security function. If the output of the security function received by the target is the same as the output generated as a function of at least the received message, the received publicly known constants, the security function, and the shared key, neither the message nor the constants have been altered.
