To verify each packet signature, the receiver proceeds with signature verification when the packet for the block is first received and stores the result in CACHE. For packet signatures sent afterwards, signature verification works based on the details stored in CACHE.

Referring to the operation of the present invention configured as described above are as follows.

First, a service provider who wants to manage a customer by using the CTP system 1 accesses a Web-Site provided with a customer management window 15 through an ISP network 2. By accessing the site, the operator can use the business of the operator among the CRM windows (eg, the CRM window (16), the bank window (17), the video window (18), the CRM window (18), and the customer database linked CRM window (19)). Down-load related program to own PC by selecting CRM window suitable for area or work type.

If the nature of the provided CRM window does not match the contents of the business, or if you want to create your own CRM Tool Kit, in the Configure Customer DB window (30), select window (31), item window (32), history input window (33). Through the selection of integrated bars 34 integrated with each other, it is possible to create a unique CRM Tool Kit (see FIG. 6, customer CRM Tool example).

Using the CRM Tool Kit configured as described above, an SMS text message can be sent through the SMS transmission server 5 to the customers managed by the operator. Vulnerable to security and forgery when SMS text messages are sent over the ISP network (2). Problems such as theft and disclaimer required the transmission of encrypted SMS messages. However, when the encryption technology is inserted into the text message, there is a problem about the processing speed. Two ways of improving the SMS processing will be described.

First, there are three major environmental variables that should be considered before suggesting ways to optimize SMS processing.

1. Network speed according to various network environments

2. Carrier Constraints for Concurrent Message Processing

3. Increased transmission data according to processing time and additional information due to message encryption

Considering these environment variables, the first improvement is to calculate the most effective message segmentation method for message processing called "Critical Point", and to shorten the overall message processing time by transmitting the message with the calculated segmentation method.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

8 is a diagram for calculating the critical point of the present invention.

The X axis 39 represents a message dividing method and the Y axis 38 represents the overall processing time. Each graph here represents a distinct surrounding environment. In the same network bandwidth, the graphs represent non-cryptographic processing time and encryption processing time, and the encryption processing time is created by dividing the overhead time caused by two environment variables, encryption, and the number of simultaneous message handling.

The circled part is the Critical Point (37), which shows its position differently according to each environment variable. By calculating the critical point using an efficient algorithm, deriving the corresponding message segmentation method, and sending the entire message, the overall message processing time is minimized, and the overhead of encryption processing time caused by the partition is improved.

Secondly, encrypting the entire message only once, and splitting and encrypting it, generally takes time multiplied by the number divided by the first time spent. The time required for encryption time is divided into two times. The time is divided into the signature time and the verification time for the message. The time is improved through the improvement, and the improved method provides four functions as follows.

1. Simplify signing for each packet.

2. Simplify signature verification for each packet.

3. Packets can be verified individually.

4. Minimize packet signatures.

The improvements will explain how these features are implemented in the signature and verification phases. The signature and verification of the packet will be a description of how to "make the packet signature data" and how to verify the signature data?

9 is a procedure of creating a packet signature, which is described below.

First, obtain the packet size to be divided for the block through the critical point, and divide the block into packets P ₁ , P ₂ , P ₃ , P ₅ , P ₆ , ..., P _N.

Block = (P ₁ , P ₂ , P ₃ ,, P ₅ , P ₆ , ..., P _N )

Then, for each packet, use h () to get the packet digests D ₁ , D ₂ , ..., D _N (D ₁ = h (P ₁ ), D ₂ = h (P ₂ ), D _N = h (P _N )) Calculate the block digest value using the calculated packet digest (D ₁ - _N = h (D ₁ , D ₂ , ..., D _N ))

Once the block digest is calculated, the block signature is obtained by signing with the sender's private key. Finally, these values are combined to obtain a packet signature as shown in FIG.

The usual way is N times different signature values are required, because the signature with the private key of the sender for the packet digest (D _i) per packet (P _i), respectively.

The packet signature consists of the packet digest and block signature except for the current packet (P _i ) and D _i , which corresponds to P _i . That is, the packet signature is the first packet digest (D _i ), packet (P _i ), The block digests are combined to send N packet signatures to each. This approach supports security requirements such as user authentication and data integrity for each packet and does not require the individual signatures required per packet. This simplification will save significant process time.

Next, the verification of the packet signature data is as follows.

When the receiver receives the packet signature for the block for the first time to verify each packet signature, the receiver proceeds with signature verification as shown in FIG. 10 and stores the result in the CACHE. For packet signatures sent afterwards, signature verification works based on the details stored in CACHE.

When the I-th packet signature (PS _i ) data is received in the block, signature verification is performed in the following order.

1 extracts the packet P _i at the PS _i.

2. Obtain the packet digest D _i for P _i .

The block digest D _1-N is obtained by combining D _i obtained in 2. and the packet digest obtained from the remaining PS _i .

4. Check that D _1-N is in the CACHE. If present in CACHE, signature verification is complete.

5. Obtain D ' ₁ - _N from the block signature S (D ₁ - _N ) using the sender's public key.

6. If D ₁ - _N and D ' _1-N are equal, signature verification is completed and vice versa. Completed D ₁ - _N are stored in CACHE and used as check data for packet signature to be received later.

A typical signature verification operation repeats five or six operations per packet. The proposed packet signature saves a considerable amount of time since the 6.5.1 operation is omitted after the first verification compared to the general method of signature per packet.

For example, when a block is divided into 16 packets and RSA 512-bit is used for signing, the packet signature scheme is 15 and 10 times faster in signing and verifying.

The present invention CTP (Client to Phone) provides a CRM Tool Kit for companies or individuals who want to use SMS text messages as a CRM Tool, through the SMS transmission program, down the CRM program for their business on-line It can provide optimized service by loading and provide security function by encrypting message to prevent leakage of SMS text message on-line and reduce the time required accordingly.
