System for and method of updating cryptographic key data server system method of providing cryptographic key updates and computer-readable recording medium

摘要

system for updating the encryption key data 120, 100 is a key input for receiving (114) a sequence of key update (106); And the sequence of key update (114) in response to receiving the key update of the includes a key data updater 108, to change the portion 116 of the encryption key data, the portion not including all of the encryption key data rather, different respective portions of the encryption key data are selected for each of the key update of the sequence of the key update. The system includes an input for receiving the content, the content data 112 to be processed (104); And the content data further comprises a password and a password processing unit 110 to acquire the processing content data 118, in accordance with the key data. Content input is adapted to receive the content data stream, a continuous stream of the content data are encrypted on the basis of the successive keys corresponding to the serial key update. ; encryption key data, keystrokes, key data updater, content, type, content, data
