摘要: A client terminal is provided with a column encryption unit that, from an key, table identifier, and generates private public comparison value, which the concealed value ciphertext, encrypting particular column; encrypted natural joining request that issues text requests regards to columns identifier. The contains as key generated by group of generating elements identifier first second a-th b-th column. An database server executes using returns results.
