Abstract(in English) | In this paper, we establish the strongest security notion by taking into account the security notions of digital signatures based on public-key cryptography and some desirable requirements for signature schemes in unconditional security setting. And we arrange the relation among security notions which have appeared in unconditionally secure schemes so far. It turns out that our security notion is the strongest among that of unconditionally secure authentication and signature schemes known so far, and that our security notion includes that of signature schemes based on public-key cryptography, e.g. existential unforgeabitity under adaptive chosen-message attack. |
