摘要:
A file transfer system including a relay apparatus is provided in which the relay apparatus includes: an incoming file sending part 15 which receives a file identifier I and a downloaded data amount O_R from a receive apparatus 50; and a file storing part 13 which stores the file identifier and file data and passes file data according to the file identifier and the downloaded data amount to the incoming file sending part. The file data F(O_R) is sent to the receive apparatus.

When an alias mail having an alias address X as a destination is received from an originator terminal, an alias mail relay server restores a recipient address R and an alias address generation argument C, generates a reply destination address Y including the generation argument C restores and an originator address S, and replaces the destination and a transmission source with the recipient address R and Y to transfer the alias mail to a recipient terminal. On the other hand, when a reply mail is received from the recipient terminal, a remailer restored the originator address S and the generation argument C from Y, regenerates X from the generation argument C restored and the recipient address R, and replaces a destination and a transmission source with the originator address S and X to transfer the reply mail to the originator terminal.
摘要:
A recipient identifier and communication condition information stored in a recipient-identifier storing unit are encrypted by an identifier-for-disclosure creating unit of a recipient terminal to create an identifier-for-disclosure. An identifier-for-disclosure notifying unit notifies a sender terminal of the identifier-for-disclosure. When a communication request using the identifier-for-disclosure is sent from the recipient terminal, a restoring unit of a relay system extracts the communication condition information from the identifier-for-disclosure. Only when communication conditions included in the communication condition information are satisfied, communication between the recipient terminal and the sender terminal is established.
摘要:
A terminal device 4 transmits a certificate issue request including a communication ID thereof and a sub ID to a certificate issuing device 7 via a NW1. The certificate issuing device 7 inquires of a communication ID checking device 5 whether or not the communication ID included in the certificate issue request is in use or not and inquires of a communication ID/sub ID checking device 6 whether or not the communication ID and the sub ID are associated with each other. If both the check results are OK, the certificate issuing device 7 generates a certificate including the ID of the certificate issuing device 7, the communication ID, the sub ID and a validity period and transmits the certificate to the terminal device 4. In this way, a certificate with a short validity period can be issued only based on the access to the NW1 using the communication ID and the sub ID.

摘要:
A terminal device 4 transmits a certificate issue request including a communication ID thereof and a sub ID to a certificate issuing device 7 via a NW1 (a first network). The certificate issuing device 7 inquires of a communication ID (identifier) checking device 5 whether or not the communication ID included in the certificate issue request is in use or not and inquires of a communication ID/sub ID checking device 6 whether or not the communication ID and the sub ID are associated with each other. If both the check results are OK, the certificate issuing device 7 generates a certificate including the ID of the certificate issuing device 7, the communication ID, the sub ID and a validity period and transmits the certificate to the terminal device 4. In this way, a certificate with a short validity period can be issued only based on the access to the NW1 using the communication ID and the sub ID.
