Data security in an information processing device |
摘要 |
A device and method for data protection of inputted and stored publicly encrypted data. Publicly encrypted data can be received by a data receiver module and stored in a storage module and be decrypted by a decryption module using a first encryption key. A deciding device can determine whether or not the data needs protection. If necessary, the data can be re-encrypted by an encryption module based on a second and different internal private encryption key generated from the encryption module and stored in the storage module. |
