Abstract: A method for managing communications within a network comprising utility meters, each associated and connected to at least one utility management center through at least one intermediate data concentrator. A message is sent by a utility meter to the destination data concentrator. This message includes metering data measurement reported by said utility meter, its utility meter identifier, the destination data concentrator identifier and the management center identifier. Then, on the basis of several metering data measurements, a metering counter differential consumption value is calculated by difference of two metering counter consumption indexes measured by the utility meter within a time period interval. Then, a report containing at least the metering counter differential consumption value is sent from the destination data concentrator towards the utility management center to which said utility meter is associated.

Abstract: A method for authenticating a user to a provider, among a plurality of providers. The method uses an authentication device comprising, for each of provider, a record comprising a pairing key and first data, both as shared data. Provider authentication data comprises a first cryptogram obtained by encrypting said first data with said pairing key. Authenticating provider authentication data is performed at the authentication device by the steps of decrypting said first cryptogram by means of the pairing key stored in one of said records, then comparing the result of this decryption with first data resulting from pairing data stored in said record, if the comparison does not indicate a match, then processing again the previous decryption and comparison steps by using the pairing key of another record until each of said records stored in the authentication device has been processed.

Abstract translation: 一种用于在多个提供者之间向用户提供认证的方法。 该方法使用认证设备，对于每个提供商，包括作为共享数据的包括配对密钥和第一数据的记录。 提供商认证数据包括通过用所述配对密钥加密所述第一数据而获得的第一密码。 通过以下步骤在验证设备处执行认证提供商认证数据：通过存储在所述记录之一中的配对密钥对所述第一密码进行解密，然后将该解密的结果与存储在所述记录中的配对数据产生的第一数据进行比较， 如果比较不指示匹配，则通过使用另一记录的配对密钥再次处理先前的解密和比较步骤，直到存储在认证设备中的每个记录已经被处理。

Abstract: A secure detachable utility monitoring device is disclosed, to be appended to a utility metering apparatus for controlling at least one utility usage consumption. A detachable metering monitoring device of at least one embodiment includes: a usage reading interface to acquire a utility consumption value metered by the utility meter; a first memory to store at least a unique identifier ID and a personal key, both pertaining to the device; a crypto processor to generate a cryptogram from information data comprising at least the utility consumption value, the cryptogram being encrypted with the personal key; a message generator to generate an information message including at least the cryptogram and the unique identifier ID; and a communication network interface including a sending unit to send the information message to a remote management center.
