A tamper-proof or vandal-proof torx bit has a hole in the middle of the bit. Easy to find. Harbor Freight has a cheap security bit set of 50 bits or something for like $10. Although the particular set I'm thinking of may not have a large enough bit for this job.

For the tamper-proof proprietary Nissan bolt, I have seen people drill out the star points on the inside of the bit and add a bite point to the rounded outside edges and then use a large tamper-proof torx bit to remove it. A small router bit on a Dremel does quick work from what I've seen on Youtube.
