摘要： A method of facilitating the lawful interception of an IP session between two or more terminals 12,13, wherein said session uses encryption to secure traffic. The method comprises storing a key allocated to at least one of said terminals 12,13 or to at least one of the subscribers using one of the terminals 12,13, at the terminal 12,13 and at a node 5,8 within a network 1,6 through which said session is conducted, or a node coupled to that network. Prior to the creation of said session, a seed value is exchanged between the terminal 12,13 at which the key is stored and said node 5,8. The key and the seed value are used at both the terminal 12,13 and the node 5,8 to generate a pre-master key. The pre-master key becomes known to each of the terminals 12,13 involved in the IP session and to the network node 5,8. The pre-master key is used, directly or indirectly, to encrypt and decrypt traffic associated with said IP session.

摘要： An air impingement arrangement and method for compensating for the curling tendency of a paper or board web which is being treated. Air impingement is disposed in connection with a paper or board process or with its finishing process and extends across the width of the web (10) running in the vicinity thereof, forming a contact-free web treatment zone, in which process the web is dried in at least one dryer unit (3, 5, 7) that applies single-wire draw. In accordance with the invention, air impingement directed at the web (10) is produced by the air impingement arrangement (20) in the web treatment zone, said air impingement including, one following after the other, at least one hot blowing with air and at least one cold blowing with air. The invention also relates to a paper or board machine provided with this kind of air impingement arrangement.

摘要： A method and arrangement for drying a paper to be surface-treated, in particular fine paper, in an after-dryer in a paper machine. The paper web is first dried in a forward dryer section of the paper machine by one or more groups with single-wire draw that are open downward on support of a drying wire, the paper web is then finished in a finishing section, e.g., surface-sized or coated, and thereafter, the paper web is dried by an upwardly open inverted group with single-wire draw. In the inverted group with single-wire draw, the tendency of curling formed in the paper web in the forward dryer section can be substantially eliminated and/or compensated for. In the alternative, to eliminate or compensate for the tendency of curling formed in the paper web in the forward dryer section, hot moist air may be fed into certain locations into connection with the dryer groups in an after-dryer in order to restrain the evaporation, or hot dry air may be fed in order to promote the evaporation from the side of the web that is desirable in view of the control of curling.

摘要： A method of authenticating candidate members 1 wishing to participate in an IP multicast via a communication network, where data sent as part of the multicast is to be encrypted using a Logical Key Hierarchy based scheme requiring that each candidate member submit a public key to a group controller. The method comprises, at the group controller 1, verifying that the public key received from each candidate member 1 is owned by that member and that it is associated with the IP address of that candidate member 1 by inspecting an interface ID part of the IP address.

摘要： A method of facilitating the legal interception of IP connections, where two or more terminals can communicate with each other over the Internet using IPSec to provide security. The method comprises allocating to each terminal T1,T2 a public/private key pair for use in negotiating IKE and IPSec Security Associations (SAs) with other terminals. Where a terminal T1,T2 is coupled to the Internet via an access network 1,2, the private key of that terminal is stored within the access network at an interception server S1,S2. When an IP connection is initiated to or from a terminal T1,T2 on which a legal interception order has been placed, the private key stored for that terminal T1,T2 within the access network 1,2 is used to intercept the connection.

摘要： A paper web (W) is dried in a forward dryer section (D) of a paper machine in downward open drying groups (G1 . . . G6) that apply single-wire draw. Then, in a finishing section the web (W) is surface-sized in a surface-sizing unit (20) and dried mainly by contact-free drying: partly by airbone web-dryers (31, 32, 34, 36) or by impingement drying. The power of the airbone web-drying/impingement drying is regulated on both sides of the web (W) such that the tendency of curling created in the web (W) in the forward dryer section (D) can be controlled.

摘要： A method for manufacturing a paper or board web in which stock is fed from a headbox (100) to a wire section (200), in which water is removed from the web (W) and from which the web (W) is passed to a press section (300), in which water is pressed out of the web (W) and after which the web (W) is dried in a dryer section (400) and reeled by means of a reel-up (800). According to the invention, additives, fillers and/or fines are fed into the stock of the surface layers of the web (W) in order to reduce the pore size distribution of the web in the surface layers so as to substantially correspond to a precoated web. The invention also relates to a paper or board machine which is characterized in that it is structured for enabling the feeding of additives, fillers and/or fines into a fiber stock such that an uncoated web substantially corresponds in its properties to a precoated web.
