IPC: H04L9/08
Filed: 1998-12-09
Granted: 2009-02-17
Abstract: La génération de clés de chiffrement asymétriques par l'utilisateur nécessite des clés de signature et de codage. Quant à la personnalisation et à la certification, elles nécessitent des liaisons fiables avec un site central. Lorsque les utilisateurs veulent générer leurs propres clés, notamment la clé de chiffrement, cela pose des problèmes de sécurité. Un procédé permet d'atténuer ces problèmes. Selon ce procédé, l'utilisateur reçoit une paire de clés générée, personnalisée et certifiée par le site central ainsi que des composants permettant de produire des paires de codage. L'utilisateur produit lui-même à un moment quelconque une paire de clés de codage, signe la partie publique de cette paire avec la clé de signature secrète qui lui a été confiée et transmet le résultat au site central, où le résultat est affecté à l'utilisateur au moyen de la partie publique certifiée de la paire de clés de signature. L'invention a comme domaines d'application toutes les formes de procédé de chiffrement asymmétrique, notamment les domaines suivants: cartes de paiement/transactions bancaires, contrôles d'accès aux réseaux/banques de données, contrôles d'accès aux immeubles/pièces, signatures numériques, identités numériques/cartes de patients.

Abstract: An implanted sensing device (1) for monitoring an analyte (e.g. blood-glucose) includes a non-toxic macromolecular material (2) encapsulated within an envelope (3) of bio-compatible semi-permeable membrane. A sensor (4) responds to change of a physical property (e.g. viscosity) of the material (2) when the analyte contacts the material (2), to signal the change to a measurement circuit (50) that together with the sensor (4) and a transponder (6) are included within the envelope (3). The transponder (6) is interrogated externally of the implanted sensor (1) by an interrogation unit (7) to transmit measurement data for processing and storage. The interrogation signal is utilised within the device (1) to power the circuit (5) and transponder (6) and conveys data to the device for re-calibration or re-setting of signal- datum values to compensate for ageing or drift.

Title: Secure mutual network authentication and key exchange protocol
Inventor: MACKENZIE PHILIP DOUGLAS
IPC: G06F21/31
Filed: 2001-02-09
Granted: 2005-04-12
Abstract: Secure communication protocols are disclosed in which two parties generate a shared secret which may be used as a secure session key for communication between the parties. The protocols are based on Diffie-Hellman type key exchange in which a Diffie-Hellman value is combined with a function of at least a password using the group operation such that the Diffie-Hellman value may be extracted by the other party using the inverse group operation and knowledge of the password. In one embodiment, each of the parties explicitly authenticates the other party, while in another embodiment, the parties utilize implicit authentication relying on the generation of an appropriate secret session key to provide the implicit authentication. Typically, the parties will be a client computer and a server computer. In accordance with other embodiments of the invention, in order to protect against a security compromise at the server, the server is not in possession of the password, but instead is provided with, and stores, a so-called password verifier which is a function of the password and where the password itself cannot be determined from the value of the password verifier.

Title: Process for producing optically active tropinonemonocarboxylic acid ester derivative
Inventor: NAKAMURA DAISAKU
IPC: C12P41/00
Filed: 1999-07-12
Granted: 2008-10-14
Abstract: An optically active tropinone monocarboxylic acid ester derivative, which is useful as an intermediate in synthesizing an optically active tropane derivative, is reacted with succinedialdehyde, an organic amine and acetone dicarboxylic acid ester to thereby give a tropinone dicarboxylic acid ester derivative. Then, the obtained product is subjected to enzymatic asymmetric dealkoxycarbonylation followed by reduction and dehydration to thereby give anhydroecgonine methyl ester. The thus obtained anhydroecgonine methyl ester shows the same optical rotation as anhydroecgonine methyl ester obtained from natural cocaine, which indicates that the former product has the same absolute configuration as the latter. In the asymmetric dealkoxycarbonylation, the optically active tropinone monocarboxylic acid ester derivative is obtained at a yield of 30 to 50 mol% and shows an optical purity of 70 to 97 %ee. By further reducing and dehydrating the optically active tropinone monocarboxylic acid ester derivative, a crystalline optically active anhydroecgonine carboxylic acid derivative can be obtained. Thus, it is found out that the optical purity can be easily elevated by recrystallization.
