摘要： The signer obtains the validity check information on the electronic certificate from the certification authority when it puts the digital signature on data and delivers the signed data, electronic certificate, and validity check information to the verifier. At this time, the certification authority creates validity check information on the electronic certificate in response to a validity check request from the signer and sends it to the signer. The term of validity of the validity check information is defined as necessary. The verifier verifies the signature and, using the validity check information sent from the signer, checks the validity of the electronic certificate.
摘要翻译：签名者在将数字签名放入数据时，从认证机构获取有关电子证书的有效性检查信息，并将签名数据，电子证书和有效性检查信息提供给验证者。此时，认证机构响应于来自签名者的有效性检查请求，在电子证书上创建有效性检查信息，并将其发送给签名者。必要时定义有效性检查信息的有效期限。验证者验证签名，并且使用从签名者发送的有效性检查信息来检查电子证书的有效性。

摘要： To verify a qualification on a network without notifying verifier privacy information that can identify as a subject of a public key certificate while keeping safety of the public key infrastructure technology. An attribute certificate validation method wherein by preparing an environment in which only an attribute certificate validation device operated by a trusted third party can access a user's public key certificate, the verifier transmits attribute certificate and signed data received from a user having presented a qualification, to the attribute certificate validation device to thereby request the device to make a check to confirm authenticity of the holder of the attribute certificate, thereby preventing the public key certificate (particularly, privacy information contained in the public key certificate) of the user from being passed to the verifier.

摘要： A print managing apparatus is provided, which is able to reduce the possibility of information leakage due to the printed material, without implementing a new function in the network printer. When there is a directive to perform printing, the print managing apparatus generates a release key, incorporates the generated release key in the print data, and transfers the print data to the network printer. Then, the print managing apparatus displays on the display device, a screen prompting for a release key that corresponds to the release key, which is printed on a printed medium together with the print data.
