ABSTRACT:
A mobile phone has an encryption module, a decryption module, an antenna, a microphone, a speaker, a main memory, and a memory connector for connecting to an expansion memory. When the expansion memory connects to the memory connector to store a document received from the mobile phone, the encryption module first generates a crypto-key and then encrypts the document into a ciphered document by utilizing the crypto-key. The ciphered document is stored in the expansion memory, and crypto-key is restricted from being stored in the main memory.
