In temporal databases, valid time (VT) is the time period during which a database fact is valid in the modeled reality. As of December 2011, ISO/IEC 9075, Database Language SQL:2011 Part 2: SQL/Foundation included clauses in table definitions to define "application-time period tables" (that is, valid-time tables). Valid time was coined by Richard T. Snodgrass and his doctoral student.

InactiveUS20080098226A1Avoid it happening againUser identity/authority verificationComputer hardwareCommunications system
A plurality of encryption communication apparatuses to which terminal apparatuses are connected are connected via a network, data received from the terminal apparatus which is a transmission source is encrypted by the encryption communication apparatus and transmitted to the other encryption communication apparatus, and data received from the other encryption communication apparatus is decrypted and transmitted to the terminal apparatus which is a transmission destination. Upon initiation of first communication with the other encryption communication apparatuses, the encryption communication apparatus generates and exchange encryption keys according to an encryption key exchange protocol, records them in the encryption key control table and, and sets validity time so as to control that. The encryption key is subjected to encryption key update when validity time is close; however, even during validity time period, when the state that CPU load is low is determined, the encryption key of the encryption communication apparatus which is a counterpart having a small communication volume is searched, and the encryption key is updated.

Handoff for satellite communication
Various aspects of the disclosure relate to handoff (e.g., idle mode handoff or other types of handoff) for a user terminal. In some aspects, a user terminal (UT) may request idle mode handoff information from a ground network (GN). Idle mode handoff information may include, for example, start times for a set of satellites, whereby each particular start time indicates when the UT may handoff to the corresponding satellite. The UT may send the request for idle mode handoff information to the GN when the UT has a defined number of valid entries (e.g., one unexpired entry) remaining in an idle mode handoff table. In some aspects, the idle UT may send the request for idle mode handoff information to the GN based on a time associated with a particular entry in an idle mode handoff table or based on a time of validity of an idle mode handoff table.

System and method for a single request—single response protocol with mutual replay attack protection
Various embodiments of a system and method for a single request—single response protocol with mutual replay attack protection are described. Embodiments may include a system that receives multiple single request messages, each of which may include a respective nonce, timestamp, and digital signature. The system may create a record of previously received nonces that, at any given time, may include multiple message nonces received within a valid period of time prior to that given time. To validate a given single request message the system may verify the digital signature of the that message, determine that the timestamp of that message indicates a time within the valid period of time prior to the current time, and determine the nonce of the that message is not present within the record of previously received nonces. The system may send a single response message that includes the same nonce as the validated message.

The invention discloses a vehicular Ad hoc network routing method based on autonomously acquired road information. The method is characterized in that when a packet forwarding direction and a vehicle driving direction are different, on the basis of the valid time of links and the distance from a predicted position of a vehicle to a target intersection, forwarding priority values of nodes are calculated, and therefore the valid time of packet transmission lines is long, and the stability of the links is improved during a routing process, and moreover, a node forwarding packet near a destination node is selected by combining the directions, and therefore the transmission time of the packet and the condition that the packet is transmitted repeatedly on the same road segment are reduced, and the time delay of packet transmission is greatly reduced. According to the method disclosed by the invention, road density information can be acquired more accurately, and moreover, routing nodes which are more efficient are selected by utilizing real-time road information more effectively. As a piecewise autonomous road density estimation method and a packet forwarding scheme of integrating a direction parameter and a position parameter are adopted by the method, the goal that the vehicle autonomously acquires the real-time road density information is achieved.

Embodiments provide an enhanced approach for Higher Priority Public Land Mobile Network (HPPLMN) search. In one embodiment, information acquired during a search (for each detected cell per frequency channel) is saved in a database and persisted in the database based on a validity time. An idle mode-to-connected mode transition by the UE, rather than aborting the search, only suspends the search for it to be resumed at a later time upon a connected mode-to-idle mode transition by the UE. Saved search data that is valid at the time of the transition is maintained and the frequency channel(s) associated with it is not re-searched in the current search. In an embodiment, the search is resumed based on weights that are associated with frequency channels, where a weight indicates a priority for visiting the frequency channel.
