Abstract: The public contracting organization must secure the reliability, fairness, and transparency of procedure when placing an order. Moreover, the public contracting organization must cut down cost and increase the efficiency of paperwork. In order to deal with these, the electronic bidding system was discussed as a national policy. In response, JACIC developed “the Electronic Bidding Core System” equipped with flexibility, functionality, reliability, safety, progressiveness, neutrality, and extendibility. Then, JACIC carried out functional improvement, adopting new Operating System, adopting new middleware, and improvement in security. Ministries and agencies, the local governments, and the public corporation use the electronic bidding core system. The numbers of users are about 700 organizations at present. In the electronic bidding core system, in order to manage a bid document safely, the code function and electronic signature function that the national government recommends are used. In the electronic bidding core system, electronic authentication is using the digital certificate. “Government Public Key Infrastructure” (GPKI), “Local Government Public Key Infrastructure” (LGPKI), and "private certificate authorities" publish digital certificates. Since the specialist pointed out reduction of the safety of the cryptographic algorithm, the national government planned to migrate the cryptographic algorithm. In the electronic bidding core system, cryptographic algorithm transition accommodated the GPKI transition schedule. My paper is about the system improvement and contracting organization support, review, and investigation in cryptographic algorithm transition.
