After receiving the information, the computing device may analyze the information to determine that the electronic signature is valid.

Abstract: Methods and systems are provided that use smartcards, such as subscriber identity module (SIM) cards to provide secure functions for a mobile client. One embodiment of the invention provides a mobile communication network system that includes a mobile network, a mobile terminal, a server coupled to the mobile terminal via the mobile network, and a subscriber identity module (SIM) card coupled to the mobile terminal. The SIM card includes a first key and a second key. The first key is used to authenticate an intended user of the mobile terminal to the mobile network. Upon successful authentication of the intended user to the mobile network, the mobile terminal downloads a function offered from the server through the mobile network. The second key is then used by the mobile terminal to authenticate the intended user to the downloaded function so that the intended user can utilize the function.

Abstract: A server protected by a firewall uses an obfuscation algorithm to periodically generate a source port number and a destination port number. The server periodically sends an outbound packet from the source port to the destination port of an arbitrary destination network address. The outbound packet passes through the firewall and configures the state table of the firewall to temporarily pass inbound packets from the destination port of the arbitrary network address to the source port of the server. A client uses the obfuscation algorithm to send a packet from the destination port of the client to the source port of the server. The packet from the client indicates that it was sent from the arbitrary destination network address and includes the real port and network address of the client within it. The server communicates with the client at the real port and network address.

Providing the service may further involve receiving a service request including the session security token, determining whether the session security token is valid, and, if the session security token is valid, generating a second service response.

Abstract: An interface device for a protected workstation or host has a network interface for connection to a multi-level secure network, a first address corresponding to a guard control port, and a second address corresponding to a guard data port. A transport guard in the device has a control component coupled to the guard control port for processing configuration data sent to the first address and producing a desired security configuration, a guard component coupled to the output of the control component and to the guard data port of the network interface, and a host interface coupled to the guard component for exchanging data with the protected host. Only when permitted by the desired security configuration, the guard component passes network data addressed to the second address of the network interface to the host interface, and passes outbound data from the host interface to the network through the guard data port.

Abstract: An enterprise system may separate the executable functionality existing in backend applications, and the separation may be at differing levels of granularity. The separated functions of the application may be registered in a catalog in the form of metadata objects. Once the executable functionality has been registered, the authorization information for each granular functional object may be associated with authorization information. In this manner, the authorization of a service of an application may be made on a feature by feature (or object by object) basis in a unified manner.

Abstract: A basic idea of this system is to separate ordered delivery data and unordered delivery data in a security protocol running on top of a reliable transport protocol, and perform a first type of security processing for ordered delivery data and a second different type of security processing for unordered delivery data in the security protocol. Preferably, data messages using ordered delivery and data messages using unordered delivery within a secure data stream are separated into two message sequence spaces on the security protocol layer, and data security processing is then performed differently in these two spaces. This system is particularly suitable for a reliable transport protocol such as SCTP (Stream Control Transmission Protocol). The security protocol running on top of the transport protocol is preferably based on the TLS (Transport Layer Security) or a TLS-like protocol with a security processing extension for unordered delivery.

Abstract: The invention relates to a method for controlling access to a private network. To a firewall node are updated logical names for mobile nodes allowed to communicate with nodes in the private network. A packet is received to the firewall node from an external network, the packet being addressed to a first node within the private network. The source address is obtained from the packet. Addresses associated with the logical names are obtained from a database node. It is checked whether the source address belongs to the addresses obtained. The packet is admitted to the private network, if the source address belongs to the addresses obtained.

Abstract: The disclosed technology provides a system and method of securely communicating data. An encryptor located at a transmitter can provide encrypted data to the transmitter. The transmitter can maintain a packet number indicating a particular packet for carrying the encrypted data and a sub-packet number indicating a position within the packet where the encrypted data is to be stored. The encryptor can produce the encrypted data using an encryptor seed generated based on the packet number and sub-packet number. A receiver can maintain a receiver packet number indicating a number of previously received packets and can compute a receiver sub-packet number. The receiver can receive a packet containing encrypted data and can decrypt the encrypted data using a decryptor seed generated based on the receiver packet number and sub-packet number.

Abstract: An apparatus and method for spatial encoding of intra-predictions for a current block of a video sequence without the need to average across a number of best template matches. The encoder identifies and sorts the best template matches for the current block within previously coded and reconstructed blocks which neighbor the current block of video. In response to determining actual predictive error for the sorted list of matches, a selector is generated identifying which of the sorted templates is optimal. The selector is then communicated for receipt by the decoder, which is adapted for performing the same template matching and sorting, which is followed by selection of the optimum candidate in response to using the selector. In response to the selector information the decoder can provide optimum template matching without the compromise or overhead of taking averages across the best template candidates.
