Apparatus and Method for Improving Security Level In Card Authentication System |
摘要 |
A memory card controller includes a random number generator and an encoder. The random number generator creates random numbers from one of a plurality of unique numbers and the encoder generates a cipher text from the random numbers and embedded keys. A memory card authentication system includes storage media and a memory card controller. The memory card controller receives the unique numbers from the storage medium. Every storage medium has a unique number that is used as a seeds to generate random numbers. This increases the randomness of the random numbers and hence enhances a security level in the memory card authentication system.
