Abstract :
The role of communication in wireless technology is very important. This communication needs to be secured. System Administration has a number of aspects of which network security is considered as very essential. We live in a world where various types of information such as voice, multimedia or data analytics can be easily accessed anywhere and at any time. So we need to make sure that information is highly secured, authentic and accessible only to the authorized user. The user must receive this information with the highest level of security. We can secure communication by various techniques such as RSS. However it has its own demerits. To overcome its issues we can use key generation techniques based on CSI information in M2M communications. For that we will use OFDM channels. The process of generating a key using CSI information can be more efficient in terms of providing security as compared to RSS based technique, as they can generate a longer key. This technique generates the key randomly thereby preventing the attacker from decoding the key within the time span during which it would be vulnerable to the communication. The CSI information of the OFDM channel has a property by which it prevents an attacker from using the same algorithm and trying to sabotage the communication, by generating a different key.
