Patent CA-2386502-A1 (CA)
Title: A method for non-repudiation using a trusted third party
Inventor: ZHANG CHUNRU
IPC: H04L29/06
Filed: 2000-10-02
Abstract: A protocol for prohibiting non-repudiation by transacting parties involved i n an executed electronic transaction, whereby a trusted third party is responsible for ensuring non-repudiation. In this protocol, a sender uses a secret sharing technology to divide the original session key into a first su b- session key and a second sub-session key. The first and second sub-session keys must be combined into the original session key in order for a recipient  to decrypt a product that is encrypted with the original session key. The sender includes the first sub-session key that is encrypted with a recipient 's public key and an encrypted product in a first message. Then the sender transmits the first message to the recipient. The recipient uses the first message as evidence of non-repudiation of origin, i.e., evidence of non- repudiation that the sender sent the transaction. The recipient transmits, t o the sender, a second message requesting the second sub-session key. The send er may use the second message as evidence of non-repudiation of receipt, i.e., evidence of non-repudiation that the recipient received the transaction. Thereafter, the sender includes the second sub-session key which is encrypte d with the trusted third party's public key in a third message that is forward ed to the trusted third party.

Abstract: L'invention concerne un procédé de concentration d'un peroxyde d'hydrogène aqueux par cristallisation discontinue. Selon cette invention, une surface de refroidissement, agencée dans une cuve de cristallisation et d'abord humidifiée au peroxyde d'hydrogène, est refroidie à une vitesse de refroidissement élevée, de sorte que des cristaux germes se forment. Cette vitesse de refroidissement est d'au moins 1 K/s, de préférence de 10 à 30 K/s. Une fois que la cuve est remplie du produit de départ, à savoir de H¿2?O¿2?, ce dernier cristallise d'abord sous la forme desdits cristaux germes pour ensuite former une couche de cristal. Lorsque la solution-mère de concentration en H¿2?O¿2? inférieure est déchargée, un processus de ressuage avec une faible augmentation de température entraîne une nouvelle augmentation de la concentration en H¿2?O¿2? dans la couche de cristal.
