摘要： A key memory medium stores a medium identifier, a medium inherent key based on the medium identifier, an encrypted user key of a user key based on the medium inherent key, and an encrypted contents key of a contents key based on the user key. A contents memory medium stores an encrypted contents software of the contents software based on the contents key. A start-up software of the contents software is executed. The medium inherent key is generated using the medium identifier. The user key is derived from the encrypted user key using the medium inherent key. The contents key is derived from the encrypted contents key using the user key. The contents software is derived from the encrypted contents using the contents key.

摘要： To reduce a load on a user terminal imposed when verifying signature data and at the same time reduce a load on a server, a signature key matrix KM includes a plurality of signature keys Ki-j arranged in a matrix structure of m rows and n columns, and is stored in a signature key matrix database 21. A correspondence relationship between a signature key set CK which is an aggregate of any signature keys selected from the n columns respectively and a user terminal 30 is stored in a correspondence relationship information database 22. A signature data generating unit 24 generates signature data having a matrix structure by encrypting a content digest D generated based on content data C by n number of signature keys included in the signature key matrix KM.

摘要： One aspect of the present invention is to provide a login system and method which can be easily applied to corporate members, and which can prevent unauthorized use even if authentication information is copied. Because of a configuration in which login is carried out by using service right data (p11) for each medium identifier (SD-ID01) of a secure storage medium (SD), unless a dishonest person uses the secure storage medium (SD), it is impossible to log in even if the dishonest person copies authentication information. Further, provided that the secure storage medium is distributed to every signal person belonging to a corporate body, it can be applied to corporate users in the same way as individual users.
摘要翻译：本发明的一个方面是提供一种登录系统和方法，其可以容易地应用于公司成员，即使复制了认证信息，也可以防止未经授权的使用。由于通过对安全存储介质（SD）的每个介质标识符（SD-ID01）使用服务权限数据（p11）执行登录的配置，除非不诚实的人使用安全存储介质（SD），否则即使不诚实的人复制身份验证信息也是不可能登录的。此外，只要安全存储介质分配给属于企业机构的每个信号人员，其可以以与各个用户相同的方式应用于公司用户。
