Abstract:
A security method and a security apparatus are disclosed which use a self-generated encryption key. The security method includes the steps of: generating an encryption key; decrypting pre-encrypted data using a pre-stored manufacturer key; and re-encrypting the decrypted data using the encryption key. The security method and apparatus minimize external leakage of data by self-generating the unique encryption key. Since the encryption keys are unique in each set, set binding is possible.
