On network security of data being transmitted is a major concern given that the data is carried on public communication channels. This suggests that if the data can be intercepted by the wrong people, there can be untold damage. In public-key cryptography today, the most popular method to achieve this is the use of different keys for encryption and decryption. In the past symmetric keys were used for cryptography which suggested the sender and recipient both required a copy of the key. During transmission, this shared key could also be intercepted, thus providing a poor form of security. It was due to this that asymmetric encryption methods were developed.

However, since the key is not to be transmitted along with the data, both the sender and recipient need to agree on which key to use beforehand. To achieve this, one method could be to use an algorithm to calculate a unique key for decrypting the data. In addition to this, there is the issue of authenticity, especially since, through the internet, there is no way of confirming that the sender of the data and the key are authentic. The solution to this has been the use of public authorities who keep records of the users and their keys.
