Crypto systems using asymmetric key algorithms do not evade a related problem.
These keys are used with symmetric key algorithms to apply confidentiality protection to information.
So that length requires, and the nature of the public key algorithms requires, much more computation.
And in fact what we're going to talk about today is symmetric key algorithms.
The coder then implements an incremental key algorithm or a random one.
Such systems almost always use symmetric key cryptographic algorithms.
A survey and taxonomy of the key algorithms for item set mining is presented by Han et al. (2007).
Not all asymmetric key algorithms operate in precisely this fashion.
Major weaknesses have been found for several formerly promising asymmetric key algorithms.
Thus, mere use of asymmetric key algorithms does not ensure security.
