<p>A method for the secure storage and retrieval of data including the steps of placing a removable user access unit into a security access port operatively associated with a computer, generating a first string of symbols, generating a second string of symbols in the user access unit based on the first string of symbols, encrypting the data based on the second string of symbols to form an encrypted data block and storing the encrypted data block in a non-volatile memory. The method also includes, during data retrieval the steps of retrieving the stored encrypted data from the non-volatile memory, regenerating the first string of symbols, regenerating the second string of symbols in the user access unit and decrypting the encrypted data based the second string of symbols to form decrypted data. <IMAGE></p> |
