As NSSAI 122 retrieves the executable instructions, NSSAI 122 may confirm that the identity of the first network slice 114A provided by first network slice artifact 106A corresponds with one of the first set of executable instructions stored on the network, confirming that the contents of the second segment of first multi-segment filename 108A have not been compromised during or following the delivery of the first network slice artifact 106A to the user. Additionally, NSSAI 122 may, along with the identity of the first network slice 114A, receive one or more authentication challenge keys from the first network slice artifact 106A also embedded in the second segment of first multi-segment filename 108A. NSSAI 122 may use the authentication challenge keys provided by the network slice artifact 106A to confirm artifact 106A is authorized to instantiate first network slice 114A.
