定义了正则密群S上的同余成分(ζ,ηα)和二元关系p(ζ,ηα),证明了(ζ,ηα)是同余成分当且仅当p(ζ,ηα)是S上的同余,最后刻划了正则密群上的最小纯正同余.
A congruence aggregate (ζ,ηα) and a relation p(ζ,ηα) for a regular cryptogroup S were defined It was proved that if (ζ,ηα) is a congruence aggregate, then p(ζ,ηα) is a congruence on S and converse The least orthodox congruence on regular cryptogroups was described finally.
