問題文
During the migration, two peers negotiate per session and may land on a quantum-vulnerable algorithm one time and a quantum-resistant one the next. Does NIST IR 8547 count that as a hybrid arrangement, if at all, and on what ground?
選択肢
- No, since each session ends up using a single algorithm for key establishment or for signing, and a combined scheme is recognized only where the two algorithms belong to the same family, in that side-by-side reading.
- Yes, since both kinds are present and in use across the estate, and the negotiation itself is the combining step that the term names, in that side-by-side reading.
- Yes, since both kinds are present and in use across the estate, and a combined scheme is recognized only where the two algorithms belong to the same family, in that side-by-side reading.
- No, since each session ends up using a single algorithm for key establishment or for signing, and running the two kinds alongside each other is described as what makes the estate work together rather than as a combined scheme, in that side-by-side reading.
