    Great post though didn’t share much on how shared secret is generated, distributed and used for authentication.
    I am investigating a case where a single user is required to register from multiple end points at the same time. How would user profile here look like? and what n SIM cards should have?
    I assume multiple PUID’s but what about PRID’s? multiple or single?
    And n shared secrets, each is on a SIM card?

    Hi Sam.

    Probably, nitty gritty details of how the HSS Authentication Vector is generated can be covered in another post ! Thanks for the feedback.

    Great Article. Any idea of any commercial/free simulations available which one can use for testing?

    There are many commercial solutions offered by vendors such as NSN, ALU, Huawei etc.
