Abstract
The randomness and amount of secret key is important to the security of key management. A combined secret key method is presented and statistical tests are performed. Generate a set of combined secret keys according to the combined secret key generation algorithm using a smart card which performs compression mapping to compose a binary sequence of a given length for statistical test. The Frequency Test, Runs Test, and Serial Test are presented in detailed. The statistical conclusion is that the combined secret key sequence is accepted as random. Consequently, combined secret key is proved secure enough for secret key generation.
