The digital signature in the digital signature file is verified and the common package is unpacked to obtain a plurality of outer packages and an encrypted symmetric key. The symmetric key is decrypted with a private key associated with the customer and each of the outer packages is decrypted with the symmetric key to obtain a plurality of identity data units.
