Abstract

Techniques for facilitating automatic Subscriber Identity Module (SIM) provisioning are described. In operation, an Auto-Provisioning (AP) configuration request for the at least one secondary SIM corresponding to a primary SIM is received. The AP configuration request comprises a first pseudo-identifier associated with the primary SIM. The primary SIM is then authenticated. Upon authentication of the primary SIM, a first secure hash corresponding to the first pseudo-identifier is derived. Thereafter, at least one second pseudo-identifier associated with the at least one secondary SIM is received. Subsequently, at least one second secure hash for the secondary SIM is derived based on the second pseudo-identifier and the first secure hash. The first secure hash and the second secure hash are then stored in a first node and at least one second node of a distributed ledger, with the first node linked to the at least one second node.
