This paper proposes a kind of Identity-Based Cryptograph (IBC) technique which based on password identification, we give a corresponding brief introduction on the characteristics, composition, and basic function of IBC , also expatiates the implement principle of IBC. We designed a network security communication system which is based on data encryption and digital signature technology. The system is practical not only because it can realize secure communication between users, but also it is much more easier to implement than others, it consists of a private key generator (PKG) and two clients. The Clients can generate users' private key by combine their own identifying information with the private key generator, the key generators send the private key to the corresponding client through secret channels and open the corresponding system parameters. Then through the private key and the corresponding identifying information, clients can encrypt, transport, decrypt information and it also can do digital signature or verify signatures and so on, so that secure communications between users can be achieved.
