Abstract:
In the migration method of the invention, for each migration request (MR) recorded in a migration control server (MCS), the following steps are performed in succession: a second mailbox (BOX2) is created in an electronic messaging service system (S2), the first access address (AD1) of the first mailbox (BOX1) that is to migrate from a first messaging service system (S1) is formed as the access electronic address giving access to the users from the outside for the second mailbox (BOX2), and the physical electronic address (ADP1) recorded for the mailbox (BOX1) is changed, in a directory database (DIR), into the physical electronic address (ADP2) of the mailbox (BOX2).
Abstract:
A method of modifying acoustic characteristics of an original audio signal as a function of modification instructions relating at least to the fundamental frequency and the spectral envelope of the original signal. The method comprises a first modification operation applied to the original signal to deliver an intermediate audio signal, the first modification operation being intended to deform the spectral envelope of the original signal in application of said spectral envelope modification instruction; and a second modification operation applied to the intermediate signal to deliver a final audio signal, the second modification operation being intended to modify at least the fundamental frequency of the intermediate signal, in application of a modification factor that is determined so as to take account of the effects of the first modification operation on the fundamental frequency of the original audio signal, so that the fundamental frequency obtained for the final signal conforms to said instruction relating to fundamental frequency.
Abstract:
A communication device for implementing a system for remotely managing at least one item of equipment by a management application able to communicate via a telecommunication network with an application embedded in the item of equipment. The device includes a first communication interface allowing implementation of a local communication link with the embedded application, a second communication interface allowing access to the telecommunication network, and a communication management device configured to communicate with the embedded application via the first interface and with the management application via the second interface, serving as communication relay between the embedded application and the management application, and configured to transmit to one of the two applications a message received from the other application, according to predefined transfer rules and as a function of at least one parameter received with the message.
Abstract:
A method for enabling a personal computer to be authenticated by a server is provided. The method comprises the step, which includes for the user in launching the execution of a log-on procedure software, introducing personal identifiers providing access to a signature private key for long-term use relative to the duration of the session. The log-on procedure software produces: identification data of the session Id, a public ephemeral module, a public exponent and at least a pair of ephemeral pubic numbers and ephemeral private numbers related by a generic equation of the type: Gi≡Qiv (mod n) or Gi·Qiv≡1 (mod n), an ephemeral certificate linking, by means of said signature private key, Id and public ephemeral module. The public ephemeral module is of reduced size relative to the signature private key.

Abstract:
A public key cryptographic method based on groups of braids. The method employs a secret key defined by a representative s of a given braid S in a braid group G, a public key defined by a representative v of the braid T(S) converted from the braid S by an operator T, and an operation of verifying the equality of two braids, i.e. the equivalence of representatives of the two braids.
Abstract:
The invention provides a method of decoding a decided signal received from a decision circuit to supply a decoded signal, said method comprising: a step of detecting a word of N bits in said received decided signal to supply a detected word; a step of selecting an admissible word of N bits in a dictionary of the error correction code used for encoding in accordance with a criterion of the shortest distance between said detected word and said selected admissible word; and a step of decoding a word of L bits constituting said decoded signal from said selected admissible word. According to the invention, the distance used in the selection step takes account of the relative reliabilities of 2K sequences of K bits, 0
Abstract:
The invention relates to a public key cryptographic method and system, a certification server and memories adapted for said system. In said public key cryptographic system, there is insufficient information contained in an electronic public key certificate alone to retrieve the public key. The inventive system comprises at least a second memory (52, 72) in which complementary information is stored, which can be used to retrieve the public key when used together with the information contained in the certificate. According to the invention, access to said complementary information is reserved to a limited number of authorised terminals among the group of terminals that can verify the certificate signature.
Abstract:
A method and an associated system for obtaining a consent from a customer (U) by means of an interactive voice server (3) following a telephone conversation between the customer (U) and a telesales advisor (A) of a call center to confirm a purchase by the customer. To this end, an interactive voice server (3) cooperates with a CTI server (7), a storage device (51), and a context memory (12).
Abstract:
A transceiver station (10) forming a node of a telecommunications network, e.g. an ad hoc sensor network, comprises means (11) for receiving a request originating from another node of the network, means (19) for determining a delay as a function of a routing metric associated with the station, and means (16, 18) for rebroadcasting the request on the network with the determined delay on condition that the same request has not already been received beforehand.
Abstract:
Disclosed is a system and method for customizing the display of text messages received by a communications terminal, such as a cell phone. The method includes downloading and installing at least one display module that controls animated rendering of a received text message with a predefined animation; recording at least one display module selection criterion, which corresponds to the installed module; analyzing characteristics of a received text message to be displayed; selecting a display module when a selection criterion associated with the display module is fulfilled by the analyzed characteristics; and submitting the received text message to the selected display module.
