    [24] The accelerated development of the Internet has changed many things throughout life. Many changes and new attempts continued, and Internet users wanted to use the Internet more easily, free from the space limitations of the wired Internet, which was connected to the Internet using existing telephone lines or leased lines. Regardless of space constraints, active wireless Internet has been developed to meet the needs of these Internet users.
    [25] However, unlike general PCs, wireless terminals (communication devices) for accessing the wireless Internet do not have complicated calculation tasks or sufficient storage space, and wireless data communication shows lower data rates than wired data communication. This follows. In order to cope with these limitations of wireless data communication, new wireless Internet access technology is being developed.Wireless Application Protocol developed by Ericsson, Motorola, etc. ) And Microsoft's Mobile Explorer (ME).
    [26] 1 is a simple block diagram of a wireless Internet using a WAP (Wireless Application Protocol).
    [27] Wireless Application Protocol (WAP) is a wireless Internet standard protocol developed by the WAP Forum, which consists of wireless carriers to provide wireless data services to wireless communication devices. The WAP Forum was formed in 1997 under the leadership of Ericsson, Nokia, Motorola, Phone.com, and more than 300 companies worldwide.
    [28] Wireless Application Protocol (WAP) uses an Internet standard protocol that supports Wireless Markup Language (WML) to solve the speed issues that arise when applying HyperText Markup Language (HTML) to the wireless. Wireless MarkupLanguage (WML) is a small markup language similar to HTML, suitable for portable devices. Built on XML (eXtensible Markup Language), it is designed to be used in one hand without a keyboard on small displays.
    [29] Wireless Application Protocol (WAP) provides a WAP Proxy type gateway between a wireless communication device and a web server to provide a function of displaying and retrieving Internet information to a wireless communication device at high speed. Gateway) supports the wireless Internet environment by acting as a translation between the WAP protocol and the TCP / IP protocol.
    [30] The Wireless Application Protocol (WAP) architecture includes the Wireless Application Environment (WAE), the Wireless Session Protocol (WSP), the Wireless Transaction Protocol (WTP), the Wireless Transport Layer Security (WTLS), and the transport. WDP (Wireless Datagram Protocol), bearers (Bearers) and the like.
    [31] WAE (Wireless Application Environment) is a development environment that can support wireless Internet service and mobile phone service. It is designed to operate on any wireless internet platform and provides general purpose application development environment based on mobile phone technology. .
    [32] Wireless Session Protocol (WSP) handles connection-oriented and connectionless session services and encodes headers and functions to optimize content delivery over the radio.
    [33] WTP (Wireless Transaction Protocol) is a simple transaction protocol that is suitable to be implemented in a mobile environment. It is executed for datagram services. It is divided into Classes 1-3 and provides differentiated services. Services provide reliability and reduce link overhead.
    [34] Wireless Transport Layer Security (WTLS) is a security protocol based on the industry-standard Transport Layer Security (TLS) known as Secured Socket Layer (SSL). Integrity, Privacy, Authentication, and Denial of Service of Service protection) function.
    [35] Wireless Datagram Protocol (WDP) provides addressing for end-to-end transmission and has multiplexing capabilities such as the Internet's User Datagram Protocol (UDP).
    [36] Bearers have designed WAP to include various transport services, and specify what kind of action WAP will perform according to each transport service.
    [37] 2 is a simple block diagram of the wireless Internet using MME (Microsoft Mobile Explorer).
    [38] Mobile Explorer (ME) is Microsoft's Small Device browser, and was developed to support a variety of data devices, unlike the Wireless Application Protocol (WAP), which focuses on mobile phones. ME is a HyperText Markup Language (HTML) browser that supports mobile phones developed to implement wireless Internet using existing Internet standards.
    [39] However, as the contents on the Internet are diversified and paid, the wireless Internet service using the above methods is gradually increasing, and the wireless communication devices (mobile communication terminals, PDAs with a wireless communication function, smart phones, etc.) are connected to the wireless Internet by the above methods. In the current situation in which billing or payment using a wireless communication device including a phone, an IMT-2000, etc. is becoming more common, a large amount of security or personal authentication procedures are required for a large amount of payment or contract act using the wireless communication device. Convenience and popularity have become necessary.

    [96] 11 is a general conceptual diagram of a hash function typically used in a digital signature.
    [97] The digital signature uses an algorithm that uses the characteristic that the encryption key and the decryption key of the public key cryptographic algorithm are different, and the client 310 who uses the digital signature uses his / her private key. The client 310 that signs the document to be transmitted and receives the document may verify the client 310 that transmits the document using the public key of the client 310 that has signed the electronic signature.
    [98] Hash function is a function that reduces long length data to fixed length data. The hash function (HF) mentioned in the cipher outputs a hash value for a specific input value X as Y = H (X). In this case, the value of Y cannot be obtained through the value of Y satisfying H (X).
    [99] In this drawing, the client (sender) 1100 that transmits the document 1110 obtains a hash value (encrypted document) 1115 using a hash function (HF) for the document, and obtains the hash value 1115. And the original document 1110 together with the receiving client 1105, the receiving client 1105 takes the hash value 1115 of the original document 1110 using the hash function HF. The value is compared with the hash value 1115 sent by the sending client 1100 to recognize that the document sent by the sending client 1100 is certain.
    [100] 12 is a simple conceptual diagram in which a secret key of a transmitting client 1100 is combined with a document encrypted through a hash function and transmitted to a receiving client 1105.
    [101] After encrypting the document to be transmitted through the hash function (HF) through the process of FIG. 11, the security and personal authentication effects can be enhanced by inserting the private key (secret key) of the transmitting client into the encrypted document 1115. . The transmitting client 1100 transmits the encrypted document 1200 in which its private key is inserted, together with the document 1110 to be transmitted, to the receiving client 1105.
    [102] FIG. 13 is a simple conceptual diagram in which the receiving client 1105 receives an encrypted document 1200 having a private key combined from the transmitting client 1100.
    [103] The receiving client 1105 obtains the public key of the transmitting client 1100 from the certification authority 300 or the like to decrypt an encrypted document combined with the secret key of the transmitting client 1100. The encrypted document 1200 into which the secret key is inserted is decrypted through the obtained public key of the transmitting client 1100. The encrypted document with the secret key released can be authenticated by the transmitting client 1100 through comparison as shown in FIG.
    [104] FIG. 14 is a simple internal block diagram of a wireless communication device equipped with an integrated chip (IC) card or application program in which an algorithm capable of processing a wireless certificate and generating a key is embedded.

    [108] The wireless communication device (all wireless communication devices including a mobile communication terminal, a PDA, a smart phone, an IMT-2000, etc. with a built-in wireless communication function) is an algorithm capable of processing a wireless certificate and generating a key. The built-in integrated chip (IC) card or application program (Application Program) is mounted, the client 310 can download and store a certificate (Certificate) responsible for the authentication of their own from the certification authority (CA) (300) have. The certificate stored in the wireless communication device may be used for the purchase of goods or other insurance of the client 310.
    [109] Fig. 16 is a simple exemplary diagram in which the client 310 selects a shopping mall after accessing the wireless Internet using a wireless communication device.
    [110] FIG. 3 is a diagram in which the client 310 receives a wireless Internet service using his or her wireless communication device. The number of wireless Internet services is gradually increasing, and according to the present invention, the client ( 310 may engage in other payment or contracts through a certificate stored in the wireless communication device.
    [111] 17 is a simple exemplary diagram in which a client 310 accessing an internet shopping mall 305 transmits order information about a selected product by using a wireless communication device.
    [112] The order information may include a certificate of the client 310 as necessary. The certificate refers to electronic data that confirms and verifies that the electronic signature public key matches the electronic signature generation key owned by the client 310.
    [113] 18 is a simple exemplary diagram in which a unique IP (Internet Protocol) address is stored in the wireless communication device of the client 310.
    [114] The IP (Internet Protocol) address may be obtained from an authorized IP granting institution 1000, and may be purchased in the form of an integrated chip (IC) card in the wireless communication device when the wireless communication device is purchased.
