![]() The internet security techniques consist of various provisions and policies, which are adopted by the network administrator so as to prevent and monitor the unauthorized access, modification, misuse or denial of. In the present day to day life, due to the inconvenience of travelling from place to place, information/messages are sent through the internet. ![]() This paper also presents an appropriate future scope related to these open fields. The proposed algorithms proved to be highly efficient in their respective grounds but there are certain areas that remained open, related to these algorithms, and have not yet been thoroughly discussed. We have also compared the importance of both these cryptographic techniques. In this paper, we have surveyed the traditional algorithms, along with the proposed algorithms based on their pros and cons, related to Symmetric and Asymmetric Key Cryptography. Based on the key distribution, cryptography is further classified into two major types-Symmetric Key Cryptography and Asymmetric Key Cryptography. ![]() Cryptography is one such technique, which allows secure data transmission without losing its confidentiality and integrity. The basic factor is, how much security, the channel provides while transmitting data. The amount of data, transferred, is not a factor. For this, many technological implementations and security policies have been developed. Attempts have been made to remove various insecurities over internet. Network security is an important aspect of information sharing.
