摘要：Service procedures and/ or message formats such as encryption and

attachment of a digital signature are properly used according to an available amount ofmoney defined in a certificate of service, network environments such as intensity ofsecurity, transmission band and locations of communication paths and operation policy,whereby the system enables to shorten service providing time, to adjust the intensity ofsecurity and to reduce the amount of information transmitted through the informationnetwork. It is preferable to encrypt a part of the information or to attach a digitalsignature to the part of the information, instead of encrypting all information orattaching the digital signature to all information. Consequently, encryption of only theimportant portion of the information can be available. It is further preferable to store apart of the information into a storage device, instead of containing a part of theinformation into the body of the message to be sent, and to contain information of thelocation in the storage device into the body of the message to be sent. As a result, theamount of information transmitted through the information network can be reduced.This technique is particularly effective for an attachment of low usage information.
