---------------
【 Knowledge point 】1
Q：What are the differences between symmetric and asymmetric cryptosystems?
ask ： What is the difference between symmetric and asymmetric cryptosystems ？

A：Symmetric key cryptosystems (or secret key cryptosystems) rely on the use of a shared secret key. They are much faster than asymmetric algorithms, but they lack support for scalability, easy key distribution, and nonrepudiation. Asymmetric cryptosystems use public-private key pairs for communication between parties but operate much more slowly than symmetric algorithms.
answer ： Symmetric key cryptosystem （ Or key cryptosystem ） Depends on the use of shared keys . They are much faster than asymmetric algorithms , But they lack the right to scalability 、 Easy key distribution and non repudiation support . Asymmetric cryptosystems use public-private key pairs for communication between parties , But its running speed is much slower than the symmetric algorithm .
