Abstract: A persistent connection is used for real-time or near real-time data transfer from a push platform on a network to a mobile station. To establish and maintain the persistent connection between the mobile station and push platform on the network, various protocols are defined over a packet connection between the mobile station and push platform. The real-time or near real-time data is pushed or sent by the push platform to the mobile station, as the data becomes available from a data source. In particular, heartbeat messages are used to determine whether or not the persistent connection is alive and available for real-time or near real-time data transfer. When the persistent connection is lost, the mobile station uses a retry connection scheme based on the number of connection attempts made by the mobile station for establishing a new persistent connection to the push platform.

Abstract: As provided herein, when using an untrusted network connection, a secure online environment can be created for a remote machine by connecting to a trusted computer with a trusted network connection. A proxy server is installed on a first computing device and shared encryption keys are generated for the first device and a portable storage device. A connection is initiated between a second computing device (e.g., remote device), connected to an untrusted network, and the first computing device, comprising initiating a proxy server protocol from the portable storage device (e.g., attached to the second device), using the second computing device. A secure connection between the first and second devices is created using the encryption keys.

Abstract: Methods for tracking attacking nodes are described and include extracting, from a database, an instance of each unique packet header associated with IP-to-IP packets transmitted over a time period. The method includes determining from extracted headers, which nodes have attempted to establish a connection with an excessive number of other nodes over a period, identifying these as potential attacking nodes, determining from the headers, which other nodes responded with a TCP SYN/ACK packet indicating a willingness to establish connections, and a potential for compromise. Nodes scanned by potential attacking nodes are disqualified from the identified nodes based on at least one of: data in the headers relating to at least one of an amount of data transferred, and scanning activities conducted by the nodes that responded to a potential attacking node with a TCP SYN/ACK packet. Any remaining potential attacking nodes and scanned nodes are presented to a user.

Abstract: Systems and methods are disclosed for preventing tampering of a programmable integrated circuit device. Generally, programmable devices, such as FPGAs, have two stages of operation; a configuration stage and a user mode stage. To prevent tampering and/or reverse engineering of a programmable device, various anti-tampering techniques may be employed during either stage of operation to disable the device and/or erase sensitive information stored on the device once tampering is suspected. One type of tampering involves bombarding the device with a number of false configuration attempts in order to decipher encrypted data. By utilizing a dirty bit and a sticky error counter, the device can keep track of the number of failed configuration attempts that have occurred and initiate anti-tampering operations when tampering is suspected while the device is still in the configuration stage of operation.

The processors direct the firewall to block or allow the transmission of data if it is ascertained that the remote system condition is not satisfied or satisfied, respectively.

Abstract: A switch sends an authentication request message to a client at intervals of a preset duration. A response message sent by the client is received. The response message carries authentication information of a user carried on the client. An authentication message is sent to a server according to the response message. An authentication reply message sent by the server is received. The authentication reply message carries information about an authentication domain authorized by the server to the user. It is determined, according to the authentication reply message, whether the authentication domain of the user is changed. If the authentication domain of the user is changed, an authentication domain change message is sent to the client according to the authentication reply message, so that the client obtains an IP address again.

Abstract: A voice-over-Internet-Protocol (VoIP) client codes audio data as printable ASCII characters, then embeds the ASCII audio data inside a cookie that is sent over the Internet within an HTTP GET message. The GET message is sent to a server acting as a call proxy or external manager that forwards the audio data to a remote client. Return audio data is sent back to the client in the normal data field of an HTTP response message from the server. When the client receives the HTTP response, it sends another GET message without audio data, allowing the server to send another response. This empty GET allows VoIP to pass through strict firewalls that pair each HTTP response with a GET. For secure-sockets layer (SSL), client and server exchange pseudo-keys in hello and finished messages that establish the SSL session. Audio data is streamed in SSL messages instead of encrypted data.

Abstract: A cookie attribute for use during secure HTTP transport sessions. This attribute points to a server-supplied certificate and, in particular, a digital certificate. The cookie attribute includes a value, and that value is designed to correspond to one or more content fields in the digital certificate. During a first https session, a first web application executing on a first server provides a web browser with the cookie having the server certificate identifier attribute set to a value corresponding to a content field in a server certificate. Later, when the browser is accessing a second server during a second https session, the browser verifies that the value in the cookie matches a corresponding value in the server certificate received from the second server before sending the cookie to the second server. This approach ensures that the cookie is presented only over specified https connections and to trusted organizations.

Abstract: A security gateway receives messages, such as URL requests, rejected by a message filter based on a set of rules. The security gateway maintains frequencies with which the messages were rejected by the rules. The security gateway finds rejected messages having a high frequency of occurrence. Since messages having a high frequency of occurrences are more likely to represent legitimate requests rather than malicious attacks, the security gateway generates exception rules, which would allow similar messages to pass through the gateway.

Responsive to an AAA access-response message, the network element determines that additional AAA access-request messages should be, at least temporarily, suppressed with regards to the subscriber end station. Responsive to determining, the network element suppresses any additional AAA access-request messages from being transmitted to the AAA server.
