| Abstract: | Aiming at the problem that encrypted data is beyond retrieve when user's secret key is lost and the insufficiency of traditional database's protecting mode,a safe and resumable secret key management mechanism is developed based on smart card and modern encryp- tion technology.This scheme can ensure the secret key's safety and availability without the third party's participation.It can also ensure no institution or individual can obtain secret key except the user.It can resume the secret key safely when the user loses the secret key.We enhance the database's safety by using a special encryption technology.The mechanism is proved safe and worthy of being popularized through security analysis. |
