Table 1 Performance comparison of coding design strategies and topology design strategies
| Â | Encoding and decoding cost | Security | Success rate | |
|---|---|---|---|---|
Coding design strategies | o(h2) - o(h3) | Shannon or weakly | ≈1 | |
Topology design strategies (ISNS) | o(h) | Weakly | Wiretappers' rate less than 0.1 | Wiretappers' rate less than 0.2, more than 0.1 |
|  |  |  | ≈1 | >0.9 |
