Explore the strength, performance, feasibility, and interoperability of cryptographic techniques.
- [Instructor] When you're choosing…a form of cryptography to utilize,…and deciding how to implement it,…you should consider four main factors:…The strength of the algorithm,…the performance of the algorithm,…the feasibility to implement it,…and its interoperability.…The strength of the algorithm refers…to how secure the resulting encrypted data is going to be.…This is usually a function of how long…the key is that's being utilized.…As discussed earlier, a 128-bit key…will be less secure than a 512-bit key…with the same algorithm.…
But, if that's the case, why wouldn't…we just use really long keys for everything we do?…Well, that brings up the second factor, performance.…The speed and efficiency of encryption is affected…by the specific mathematical algorithms…that are being used by that encryption suite,…and the length of the key.…If you have a more complex mathematical…function being utilized, it may be more secure,…but it's also going to be much slower to perform.…The same holds true for the use of longer keys,…
