To realize world wide programming environment in which not only data but services and programmes also are shared on the networks is the aim of OZ. And in such environment, it is important to keep security. Enciphered communication described here is a OZ's securitymechanism against the eavesdropping. In OZ, encryptors and decryptors are implemented in the application level, so sofware package could be linked easily. The owner of cells, which are objects accessible over networks, can assign a set of ciphers to each cell according to the importance of data in it, so security setup could be fine-grained and flexible. By introducing combined packet which contains data for negotiation and encypted data according to the cached information about cipher, a remote method invocation could be completed with two turn-around communication between caller and callee including negotiation of cipher in the worst case.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"24","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告システムソフトウェアとオペレーティング・システム（OS）"}],"bibliographicPageStart":"19","bibliographicIssueDates":{"bibliographicIssueDate":"1997-08-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"77(1997-OS-076)","bibliographicVolumeNumber":"1997"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
