1. allow user to communicate with each other and exchange message, swap file.But information interchange is not direct, needs the server being positioned at center and coordinate.Because the number of server only has one (even if having multiple also very limited), easily there is single failpoint in system.
2. single server is in the face of numerous clients, and due to the restriction of CPU ability, memory size, the network bandwidth, the client that can simultaneously serve is very limited, poor expandability.
3. the data on server are easily subject to network attack, or the problem of server own brings security threat.
4., on namely burning after readding, the outer originating party of file cannot confirm whether read rear file is really destroyed, is not replicated.
The explanation of nouns that the present invention relates to:
P2P: the abbreviation being peer-to-peer, the meanings such as peer has in English " (status, ability etc.) coordinate ", " colleague " and " partner ".P2P can be understood as the meaning of " partner is to partner ", or is called Peer-To-Peer.Briefly, P2P is exactly computer, the swap file that people can be directly connected to other users, instead of is connected to server as before and goes to browse and download.
Namely burn after readding (Burnafterreading): just can know from literal meaning: file viewed from reader after oneself destroy (self-destructing), be a kind of technology of administering digital file survival mechanism.
Network address translation NAT (NetworkAddressTranslators): network address translation produces when IP address lacks day by day, its main purpose is exactly in order to can address reuse.NAT is divided into two large classes from historical development, basic NAT and NAPT (NetworkAddress/PortTranslator).NAPT not only can change the IP address of the IP datagram through this NAT device, also can change the TCP/UDP port of IP datagram.
IP address of internal network: refer to the private address used in A/B/C class, the IP address of distribution is not feared in the whole world uniqueness, also therefore directly cannot be accessed by other outer net main frame.
Public network IP address: refer to have globally unique IP address, can directly by other host access.
TCP (TransmissionControlProtocol): belong to transport layer protocol is the reliable data transmission under IP world, and the service that it provides comprises data stream, reliability, effectively Flow Control, full-duplex operation and multiplexed.By SCCP connection-oriented, end-to-end and reliable Packet Generation.
UDP (UserDatagramProtocol): belong to transport layer protocol is the agreement corresponding with TCP.It is that it does not connect with the other side towards disconnected agreement, but directly just Packet Generation is gone over.
Advanced Encryption Standard (AdvancedEncryptionStandard, AES): the specification being encrypted electronic data used for American National Standard and technical research is a new cryptographic algorithm that may be used for protecting electronic data.Specifically, AES is the password of an iteration, symmetric key grouping, and it can use 128,192 and 256 keys, and with 128 (16 byte) block encryptions and data decryption.Symmetric key cipher uses identical secret key encryption and data decryption.The figure place of the enciphered data returned by block cipher is identical with input data.Iterative cryptographic uses a loop structure, repeats displacement in the cycle and replaces input data.AES256 uses 256 secret key encryptions and data decryption exactly.
