[Technical field to which the invention belongs] The present invention relates to a profitable system, in particular-a kind of electronic connection that directly activates a computer's security files to encrypt or decrypt data using a security key that is used for encryption and decryption. For IC smart card;; = For those who do not need to borrow f card reader. Full text magic mechanism with electronic stamp function [Previous technology] = In the computer industry, security has become a major issue among industries. The population of follower computers has grown rapidly, no matter whether it is storage or files in the office Processing is highly dependent on the use of computers. This trend has also led to the widespread use of personal information equipment, such as portable computers; therefore, in the workplace, if such information equipment has not been properly protected, it may even be subject to unsafe protection. The invasion of the authorized person, resulting in the storage of important information used and copied by others, will cause irreparable losses to the user. Commonly known computer system protection methods include password setting program protection, basic input / output system (B 10 S) password, and later emerging I ^ smart card protection. These methods are implemented to prevent unauthorized use. The user initiates access to the computer or copies confidential files on the computer. However, although the implementation methods of the various methods are different, the summary has a common feature, that is, the unlocking key has only one corresponding unlocking IC smart card or only one set of corresponding unlocking password, etc .; the 1C smart card itself has the authentication The functions of authentication, encryption and security protection, so that the data can be transmitted and received securely according to actual needs, and the data can be safely stored as required. However, although 1C smart card (SMART CARD) is quite safe

However, it is necessary to use a card reader to read the information stored in the IC smart card = direct benefit "quote two plugs: system, the same as"] the same security machine with smart cards for the purpose of providing power " Electronic key confidential information: 糸 Using the stored file to encrypt or unlock the electronic key, directly activate the security system in the computer system, save the Tianshi "uniform card reader, similar to the security of 1 c smart card Mechanism and electronic seal function. In order to let the panel reviewer have a better understanding of the present invention, here is a detailed description of the present invention with the illustrations: [Summary] Please refer to the first figure for the electronic key of the present invention丨 Appearance diagram, = one end of the Hai Key 1 has a "^ 皋 丨 丨", which ⑽ ^ 皋 丨 丨 is connected to the circuit board 12 inside the electronic key 1, see Figure 2 and Figure 3, Circuit Board 1 2 The main parts are equipped with main I c 1 3, oscillator 1 4, touch switch 1 5, LED 16 and encrypted 1C 17 ... and other electronic parts; electronic key! There are a button 18 and an indicator light 19 at the top, wherein the button 18 can press the touch switch 5 and the indicator light 9 can provide the flashing light of LED 16. The USB port 11 is a universal serial bus (Universa) [Serial Bus] port, which is connected to the input port of the computer system ι〇. The USB port 丨 丨 can also use the RS 232 port or other peripheral interfaces. The encryption IC 1 7 series includes an electronic erasable programmable read memory (EEPR0M, electrically erasable programmable read

onU = em〇ry) 171, 172, 173 can be used to store a random parameter, and then store the A Ik machine parameter in the storage device of the computer system, and store the random parameter in the electronic key 1. Please refer to the fourth figure, which is a basic encryption and decryption block diagram of the present invention. 'The main IC 13 in the electronic key i is connected to the computer system jPC via the USB port 丨 10] and is added by the computer system 丨 〇 The decryption function is directly stored in Gade and IC 1 7. The password is generated by the computer system (PC) 1 0. This type of encryption and decryption function has the lowest cost, but is secure. It is cracked by a program. As shown in the fifth figure, it is an enhanced encryption and decryption block diagram of the present invention, in which the encryption key 1 in the electronic key 1 (: (〇PTIC) 17 includes a connection with a computer system (PC) 10, and the computer System 10 access or; Kaohsiung, one time, the password is generated by the encryption IC 丨 7; this kind of plus uses the new ID 17 to store a single ID as the encryption key, and generates a strong second-system scrambled) mechanism, its cost Slightly higher, it can be used for phase control, and y controls the encryption and decryption method and provides the encryption IC 17 one code (ID) for control and tracking purposes.
