Portable electronic device with enciphering function and its realizing method

Abstract

The portable electronic equipment (PEE) includes a main body of PEE and a connection module. Through the connection module, PEE is connected to a computer. The main body includes a transmission interface (TI), a process unit, and a memory unit. Through the connection module, TI is connected to digital interface of the computer. Through the TI, PEE carries out communication with the computer. The process unit connects and processes the communication procedure between PEE and the computer. The memory unit stores a cipher key. When PEE is connected to the computer, the computer can call the cipher key to encrypt the file to be transmitted, and transmit the encrypted file. PEE increases security of encrypted file and expedience.

Description

【Technical field】 [0001] The invention relates to a portable electronic device with encryption function and its realization method. 【Background technique】 [0002] With the rapid development of computer network technology, people's dependence on the network is also increasing, and a large amount of information needs to be transmitted through the network. The Internet is an open system for the public, and the confidentiality of information and the security of the system are not fully considered. How to protect the content of computer information, that is, the confidentiality of information content is becoming more and more important. Through data encryption technology, the security of data transmission can be improved to a certain extent, and the integrity of transmitted data can be guaranteed. A data encryption system includes an encryption algorithm, plaintext, ciphertext, and a key. The key controls the encryption and decryption process. The entire security of an encrypt...

Problems solved by technology

[0003] We generally store the key in the computer, or use a special key card to store the key, and read the key in the key card through a special card reader, but sometimes the computer system crashes , damage and other phenomena, resulting in the destruction or loss of the key. Although the key card and card reader are relatively safe, they are expensive and inconvenient to use
