随着网络用户的增加和信息化的不断发展,信息化的经济效益直接体现在日常的交流和电子商务中,保证信息及时性、准确性和安全性显得尤为重要,对发送的数据进行安全加密能防止中间人对信息的窃取和攥改,保证信息的准确性.
\x05密码技术是信息安全中的关键技术.密码技术主要包括加密/解密技术、认证技术等.通过密码技术的应用,在实际的网络通信中,可以使通信的数据保证数据安全性和数据完整性,掌握前沿的密码技术可以是网络通信的安全大大提高,而密码系统的安全都是依赖于密钥的安全.因此,如何保证会话密钥的安全性,如何通信双方能安全有效的协商出一个共同的会话密钥是一个非常重要的问题.本论文的重点就是研究群组密钥协商协议中的会话密钥,以及主流的加密算法等.
\x05由于密钥协商的重要性,密钥协商的研究成为了密码学中一个研究的热点.本论文前半部分主要介绍密钥协商的一些基本概念和协议算法,同时对人们在这方面的研究成果,后半部分主要是个人对密钥协商协议算法的理解和应用,通过简单的程序实现对数据的加密/解密的使用,实现简单网络通信的安全.

As the network users increases and the continuous development of information,information,the economic benefit directly reflected in daily communication and e-commerce,ensuring information timeliness,accuracy and safety is particularly important to send data,can prevent intermediaries to secure encrypted information to steal and crafting change,guarantee the accuracy of the information.
Password technology is the key technology of information security.The password techniques mainly includes the encryption/decryption technology,the authentication technology,etc.Through the application of the password techniques in the actual network communication,can make communication data to ensure that the data security and data integrity,grasps the frontier password technology can is network communication security greatly improved,and the password system security are dependent on key safety.Therefore,how to guarantee the safety of session key,the communication is safe,effective,how can the negotiation of a joint session keys is a very important problem.This thesis is to focus on research group of the key agreement protocol session keys,as well as the mainstream encryption algorithm,etc.
Because of the importance of key agreement,key agreement research became cryptography a research hotspot.This paper mainly introduces key agreement half some basic concepts and agreement on people in the algorithm,and the research achievements,empress half part mainly individuals for key agreement protocol algorithm,understanding and application of through simple program realization of the data encryption/decryption,realize the use of simple network communication safety.
