Limitations of encryption algorithms

“

- [Presenter] Every security control has limitations and weaknesses, and encryption algorithms are no exception. As a security professional, you should be aware of the different limitations that exist with different approaches to encryption. First, different encryption algorithms have different performance profiles. The speed of one algorithm may be much faster than the speed of another, depending upon the computational overhead involved. For example, asymmetric encryption algorithms are generally much slower than symmetric encryption algorithms. Algorithms get stronger as you increase the size of the encryption key that you use with the algorithm. The longer the key, the more resistant it is to brute force attacks. However, this leads to a resource for security constraint. Longer keys might be more secure, but they also require more computing power and therefore take longer to perform encryption and decryption…
