| Abstract(in English) | In Sept. 1990, the present authors firstly discussed DLP over composite number and presented an ID-based Key Sharing Scheme referred to as MK1. In 1991, Maurer and Yacobi presented the similar scheme, referred to as MY, which is similar to our scheme, MK1. Unfortunately the schemes MK1 and MY are not secure, In Dec. 1990, the present authors presented a secure ID-based key sharing scheme referred to as MK2. With a rapid progress of computer power for a last 15 years, our proposed scheme would have more chance to be applied practically. Regrettably, it is not widely known the fact that (i) the schemes MY and MK1 are not secure, (ii) there exists a secure scheme, MK2. At this time, present authors review MK2 and clarify the difference between MK2 and other schemes from the standpoint of security. |
