System and method for improving data input by using word frequency to text predict input. Other systems and methods include analyzing words already contained in a document (e.g. spell checking and OCR) and using word frequency to create a proxy system to reduce the space required to store data, allowing for more efficient usage of storage and enhancing the embedded content of matrix codes. The system displays the most common words in a language based upon the previously entered or displayed word(s), or the previously entered or displayed character or characters. Words with the most common frequency of use with the prior word(s) are displayed in a table to enable the user to quickly select one of the displayed words for rapid data entry. The input device can be a touch-sensitive display or non-touch sensitive type device.

A service consumer that utilizes a cloud-based access service provided by a service provider has associated therewith a network that is not capable of being controlled by the service provider. An enterprise connector is supported in this uncontrolled network, preferably as an appliance-based solution. According to this disclosure, the enterprise configures an appliance and then deploys it in the uncontrolled network. To this end, an appliance is required to proceed through a multi-stage approval protocol before it is accepted as a “connector” and is thus enabled for secure communication with the service provider. The multiple stages include a “first contact” (back to the service) stage, an undergoing approval stage, a re-generating identity material stage, and a final approved and configured stage. Unless the appliance passes through these stages, the appliance is not permitted to interact with the service as a connector. As an additional aspect, the service provides various protections for addressing scenarios wherein entities masquerade as approved appliances.

A system for facilitating secure network communications includes a security computer system and corresponding software. The security system is utilized in conjunction with a voice browser residing on a server system. A user accesses the network by placing a call to the voice browser system. The voice browser includes a software module that creates a secure connection to the security system. The user provides an identification to the voice browser system that is transferred to and verified by the security system. Once the identification is verified, the user is prompted by the voice browser system to speak a phrase for voice verification. The verification speech signals are transferred from the voice browser system to the security system to verify those speech signals against speech signals of a particular authorized user associated with the identification and stored in a database. When the user is verified, the security system retrieves a user private key and certificate from the database. In response to the user subsequently accessing a web site residing on a secure server, the secure server and voice browser system initiate a secure key exchange. During the key exchange, data packets containing security information are transferred from the voice browser system to the security system for processing, while security information from the security system is transferred to the secure server via the voice browser system. The resulting session key is securely transferred to the voice browser system to facilitate secure communications between the voice browser system and secure server.

Communications between a host information handling system and its management controller sent through a shared LOM are re-directed at the LOM from communication through a network to instead communicate directly between the host information handling system and management controller. A management module compares destination addresses of packets sent from the host information handling system and the management controller with host information handling system and management controller network addresses stored on the LOM. Packets having destination address that match a host information handling system or management controller network address are redirected from communication across the network to communicate directly between the host information handling system and management controller.

In a network system (100) for wireless communication an enrollee (110) accesses the network via a configurator (130). The enrollee acquires a data pattern (140) that represents a network public key via an out-of-band channel by a sensor (113). The enrollee derives a first shared key based on the network public key and the first enrollee private key, and encodes a second enrollee public key using the first shared key, and generates a network access request. The configurator also derives the first shared key, and verifies whether the encoded second enrollee public key was encoded by the first shared key, and, if so, generates security data and cryptographically protects data using a second shared key, and generates a network access message. The enrollee processor also derives the second shared key and verifies whether the data was cryptographically protected and, if so, engages the secure communication based on the second enrollee private key and the security data.

The invention discloses an energy consumption module, an offshore wind power flexible DC transmission system, and a fault ride-through strategy applied to the offshore wind power flexible DC transmission system. A DC chopper module is integrated into the MMC of an onshore converter station. The DC chopper module uses a modular arrangement and is connected in series with the SM sub-modules of the MMC. The DC chopper module does not contain capacitor components. When an onshore AC fault occurs in the offshore wind power flexible DC transmission system, the DC voltage rises sharply. A certain number of DC chopper modules (DMs) are introduced to consume surplus power through the energy-consuming resistors to maintain the system's short-term stability. After the fault is removed, the corresponding DMs are removed in order to complete the system fault ride-through. Through the modular arrangement of DMs in a bypass state during normal operation, not only can the precise matching of the surplus power be achieved, the electrical quantity fluctuations of the switching process of the chopper device can be greatly reduced, and fault ride-through and isolation are realized, but also the DM issimple in structure and good in economical efficiency.
