Protecting integrity and confidentiality for data communication
Fangyong Hou, Zhiying Wang, Yuhua Tang, Zhen Liu · 2004
This work presents a scheme to build data communication system that can effectively protect data integrity and confidentiality. Firstly, This work briefly introduces the situation of integrity and confidentiality protection. Then, This work brings forward a new cipher, which uses a keystream generator to produce infinite number of frame secret keys basing on an infinite root key space, and use a unique one-off frame secret key for each data encryption/decryption. Basing on this cipher, we construct a data communication system. This work illustrates how to build such a system and analyze its protections of data integrity and confidentiality. With the character of cipher, it offers high resistance against cryptanalysis to prevent data disclosure, and it gives little opportunities to those intractable attacks that can compromise data integrity.
