    摘要： 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.

    摘要： A method and cryptographic system for descrambling content packets, included within a digital transport stream, having conditional access messages and header data. The method and system require a deciphering algorithm, processed by a descrambler of a multimedia unit, using an initialization vector as a first input and a control word as a second input. The multimedia unit is connectable to a security module for processing the conditional access messages and extracting control words therefrom. The initialization vector, or intermediate data to determine the initialization vector, is the result of a cryptographic function based on at least one variable extracted from the digital transport stream and processed by the security module.
