Query: Decoding Orders for Securing Untrusted NOMA   This letter focuses on exploring a new decoding order to resolve the secrecy
issue among untrusted nonorthogonal multiple access users. In this context,
firstly, we identify the total number of possible decoding orders analytically.
Then, we propose a decoding order strategy ensuring positive secrecy rate for
all users, and obtain the number of feasible secure decoding orders based on
this proposed strategy numerically. Thereafter, we present a suboptimal policy
to avoid the computational complexity involved in finding the best secure
decoding order. Numerical results illustrate that the suboptimal solution
provides a performance gain of about 137% over therelevant benchmark.
