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.

[ We claim:] [1.] A method of generating an electronic identifier for a single-chip network interface unit (NIU) connected to a data network for use in detecting unauthorized decryption by the NIU of encrypted data transmitted over the data network, said method comprising the steps of:generating a random number by using a random generator comprising a component of the NIU on the NIU chip;storing said generated random number in a memory of the network interface unit, said stored random number comprising a private key for use by the NIU in decrypting received encrypted data so that said stored random number is inaccessible outside of the NIU;calculating a public key from the private decryption key using a non-invertible mathematical formula;determining if said calculated public key is unique; andstoring, as an electronic identifier of the NIU, at least a portion of the unique public key in a database accessible by the data network.
