Problems solved by technology

[0004] However, the traditional security method is quite inconvenient. When the user temporarily leaves the mobile communication device, he may not remember to encrypt the interface of the mobile communication device, causing the content of the short message to leak out.
Or, when the mobile communication device is encrypted, when it is necessary to inquire about other data in the mobile communication device, a password must be input, which is an inefficient and low-security approach
[0005] Furthermore, when the mobile communication device is temporarily lent to others for use, it is easy for others to secretly read confidential or private text messages, which is very inconvenient for the security of text messages

Embodiment Construction

[0027] see figure 1 , the mobile communication device 1 has a display screen 11, a buffer 12, an editing module 13, an encryption module 14, a communication module 15 and a memory module 16; the communication module 15 and the editing module 13 are all connected to the buffer 12; The buffer 12 is connected to the memory module 16 through the encryption module 14 .

[0028] The mobile communication device 1 can be a commonly known mobile phone, and must be able to receive and send at least one short message M.

[0029] see figure 2 , the register 12 is set in the mobile communication device 1, and can use volatile memory, such as DRAM, SRAM, etc., or can use non-volatile memory, such as flash memory, which is used to temporarily store the short message M. The short message M can be received by a communication module 15 in the mobile communication device 1 from an external short message M, or the short message M that the mobile communication device 1 utilizes an editing modul...

Abstract

The invention relates to a short message encrypting method and a mobile communication device encrypting short messages by using the same. The short message encrypting method comprises the following steps of: (1) selecting at least one short message to be encrypted; (2) inputting a code; (3) combining the selected short message with the input code to generate encrypted data, and also eliminating the input code. The invention only encrypts the short messages without influencing on reading other data, thus when the mobile communication device is not used, the code does not need to be set every time; when the data inside the mobile communication device need to be temporarily inquired, the mobile communication device an be used at once; or when the mobile communication device is not carried or is lent, the leakage of short message data needs not to be worried.

Description

technical field [0001] The invention relates to a short message encryption method and a mobile communication device using the short message encryption method. Background technique [0002] At present, general mobile communication devices all have a short message function, which provides users with the ability to transmit data information to a remote location in different ways when it is inconvenient to talk on the phone. [0003] Regardless of whether it is commercial or private, it is often necessary to transmit some highly private content. However, the current mobile communication devices on the market do not have the function of keeping secrets for short messages. The most common security method is to set a password for the entire mobile communication device, so that the mobile communication device enters a preset screen, and the mobile communication device must be operated only after entering the password. [0004] However, the traditional security method is quite incon...
