20110016320 | METHOD FOR AUTHENTICATION AND SIGNATURE OF A USER IN AN APPLICATION SERVICE, USING A MOBILE TELEPHONE AS A SECOND FACTOR IN ADDITION TO AND INDEPENDENTLY OF A FIRST FACTOR - The invention relates to a method for the two-factor authentication of a user in an application service running on an application server. The first authentication factor is a PIN authentication code known only by the user and the application service, and the second authentication factor is the mobile communication terminal of the user on which is installed a reliability application obtained from a reliable third party or certified by the same. The reliability application is capable of generating, using the PIN authentication code and a secret key shared only with the reliable third party, a single use authentication code for each authentication of the user in the application service. | 01-20-2011 |
20110264917 | METHOD FOR TWO STEP DIGITAL SIGNATURE - The invention relates to a method for the digital signature of a message by a signer having an identity and holding a signature device, in which a public key cryptographic scheme is used. The signer has a public key and two private keys, the second private key being deposited at a reliable third party. For each signing operation, two additional steps are respectively carried out with a separate private key, i.e.: the calculation by the signer of a pre-signature of the message using the first private key, and transmitting the message and the pre-signature to the reliable third party; and the verification by the reliable third party of the pre-signature followed by the calculation by the reliable third party of a signature of the message using the second private key deposited at the reliable third party as well as the pre-signature previously calculated by the signer. | 10-27-2011 |

20120046438 | POLYAMIDE MANUFACTURING PROCESS - A method for making polyamide is described. More particularly, a method for making a polyamide from at least one diacid and one diamine, that includes a step of concentrating an aqueous solution of diacid and diamine salt up to a salt weight concentration higher than 85%, and a polymerization step up to a desired polymerization degree is described. | 02-23-2012 |
20140349046 | PROCESS FOR PREPARING POLYAMIDE GRANULES AND USES - The subject matter of the present invention is a process for preparing polyamide granules having heat-resistance properties, and also the use of these granules, in particular in the aid of the manufacture of yarns for airbags or for tyre cords. More specifically, the invention relates to a process for preparing polyamide granules having heat-resistance properties by wet impregnation of the granules with an aqueous solution comprising at least one heat stabilizer. | 11-27-2014 |
