Abstract: PCT No. PCT/EP93/00677 Sec. 371 Date Aug. 9, 1995 Sec. 102(e) Date Aug. 9, 1995 PCT Filed Mar. 20, 1993 PCT Pub. No. WO94/22253 PCT Pub. Date Sep. 29, 1994The present application concerns a method and an apparatus, in a communication network, for processing the various fields of a protocol header preceding a data stream to provide a unique connection identifier for processing the data stream. All relevant protocol information is extracted from the protocol header for look up in a Content-Addressable Memory (CAM) (80). Each time an entry in the CAM (80) matches protocol information applied to the CAM's input (84), the CAM address of this storage section, i.e. the address of a row of the CAM (80), is provided at the output (82) thereof. The CAM addresses obtained from the protocol header are concatenated by means of a Connection Number Builder (CNB, 95) resulting in a unique connection identifier provided at the Protocol Filter's output (96) to be used for the processing of the data stream.

Abstract: Die Erfindung bezieht sich insbesondere auf ein Verfahren für eine sichere PIN-Verwaltung einer für Benutzer vertrauenswürdigen Einheit (10), die über ein Datenverarbeitungsmittel (15) verfügt, das mit einem dauerhaften Speicher (15'), einem nicht dauerhaften Speicher (15') und Schnittstellen (17, 18, 20) für das Verbinden oder Zusammenwirken mit einem Benutzer (1), einer Speicherkarte (16) wie z. B. einer Smartcard und einer Datenstation (30) verbunden ist, wobei das Verfahren die folgenden Schritte umfasst: Bereitstellen der mit einer Speicherkarte (16) verbundenen Einheit; Empfangen in der Einheit: eine externe PIN und eine Karten-PIN, wobei letztere in der Lage ist, die Speicherkarte zu entsperren; Erzeugen und Speichern eines Schlüssels in dem dauerhaften Speicher über das Datenverarbeitungsmittel und aus den empfangenen PINs, so dass die Karten-PIN anhand einer Funktion, die in dem dauerhaften Speicher gespeichert ist, berechnet werden kann, wobei die externe PIN und der Schlüssel als Argument verwendet werden; Empfangen einer Benutzereingabe der externen PIN in der Datenstation und Übertragen der externen PIN an die Einheit; Anweisen des Datenverarbeitungsmittels, die Karten-PIN unter Verwendung der gespeicherten Funktion zu berechnen; und Verwenden der berechneten Karten-PIN, um die Speicherkarte zu entsperren.

Abstract: The invention is notably directed to a method for secure PIN management of a user trusted device (10) having computing means (15) coupled to a persistent memory (15"), a non-persistent memory (15') and interfaces (17, 18, 20) for coupling to or/interacting with a user (1), a memory card (16) and a terminal (30), the method comprising the steps of: providing the device coupled to a memory card (16); receiving at the device: an external PIN and a card PIN, the latter capable of unlocking the memory card; generating and storing a key on the persistent memory, via the computing means and from the PINs received, such that the card PIN can be computed via a function stored on the persistent memory, taking the external PIN and the key as argument; receiving, at the terminal, user input of the external PIN and communicating the external PIN to the device; instructing the computing means to compute the card PIN using the function as stored; and using the computed card PIN to unlock the memory card.

Abstract: The present application concerns a method and an apparatus, e.g. in a Token-Ring adapter of a communication network, for processing the various fields of a protocol header preceding a data stream to provide a unique connection identifier for processing said data stream. All relevant protocol information is extracted from said protocol header for looking up in a Content-Addressable Memory (80). Each time an entry in said CAM (80) matches protocol information applied to the CAM's input (84), the CAM address of this storage section, i.e. the address of a row of said CAM (80), is provided at the output (82) thereof. The CAM addresses obtained from said protocol header are concatenated by means of a Connection Number Builder (CNB, 95) resulting in a unique connection identifier provided at the Protocol Filter's output (96) to be used for the processing of said data stream.
