Both approaches have their advantages and disadvantages. Obvious advantages of symmetric encryption are fast speed and simplicity. There is a much simpler algorithm for the process and the program is less complex also. This means that it takes less of CPU time to execute and proves to be the more viable option when very frequent transfers of data are being done with relatively lesser need for security. (Clercg, 2006)
However, Symmetric encryption is less secure and less reliable compared to the Asymmetric encryption. Because the entire encoding and decoding are done through one key, it is prone to be easily cracked by “brute force” attack, in which all possible keys are tested until the one that works is determined (Clercg, 2006). Besides that, more managing is required to ensure safety in the transfer of the file and key e.g. a secret channel is set up to transfer the secret key (Clercg, 2006).
Asymmetric encryption has many advantages over Symmetric encryption. Firstly, no secret channel is required to send the public key so less management is needed. Secondly, it offers a much higher level of security and privacy and it is much more difficult to crack.
