    • A method and apparatus of printing a document in a secure manner, includes receiving, by a printer, print data that has been encrypted using a printer public key. The printer-public-key-encrypted print data is decrypted by the printer using a printer secret key, to obtain decrypted print data as well as user identification information provided with the print data. Print pre-processing is performed by the printer on the decrypted print data, to thereby obtain pre-processed print data. The pre-processed print data is encrypted by the printer using a user secret key to obtain user-public-key-encrypted print data, and the user-public-key-encrypted print data is stored. The user-public-key-encrypted print data is decrypted and printed by the printer upon receipt of a user secret key, prior to printing the print data.
    • 一种以安全的方式打印文档的方法和装置,包括由打印机接收使用打印机公钥加密的打印数据。 打印机 - 公开密钥加密的打印数据由打印机使用打印机秘密密钥解密,以获得解密的打印数据以及与打印数据一起提供的用户标识信息。 打印机在解密的打印数据上执行打印预处理,从而获得预处理的打印数据。 预处理的打印数据由打印机使用用户密钥加密,以获得用户公开密钥加密的打印数据,并且存储用户公开密钥加密的打印数据。 在打印打印数据之前,用户公开密钥加密的打印数据在打印机接收到用户密钥时由打印机解密和打印。
