Abstract
The generation of electronic identifiers for network interface units connected to a data network for use in detecting unauthorized decryption of encrypted data transmitted over the data network. A random number is generated for use as a private key decryption code and is stored in memory in each network interface unit. A public key is calculated from the stored private key using a non-invertible mathematical formula. If the calculated public key is unique, then a portion of the public key (e.g. a subset of its bits) is stored in a data provider database as an electronic identifier for use in detecting unauthorized decryption of data by the interface unit.
