Difference between symmetric and asymmetric encryption in network security
Answers
Answer:
Difference Between Symmetric and Asymmetric Encryption
Symmetric encryption uses a single key that needs to be shared among the people who need to receive the message while asymmetrical encryption uses a pair of public key and a private key to encrypt and decrypt messages when communicating.
Symmetric encryption is an old technique while asymmetric encryption is relatively new.
Asymmetric encryption was introduced to complement the inherent problem of the need to share the key in symmetrical encryption model, eliminating the need to share the key by using a pair of public-private keys.
Asymmetric encryption takes relatively more time than the symmetric encryption.
Conclusion
When it comes to encryption, the latest schemes may necessarily the best fit. You should always use the encryption algorithm that is right for the task at hand. In fact, as cryptography takes a new shift, new algorithms are being developed in a bid to catch up with the eavesdroppers and secure information to enhance confidentiality. Hackers are bound to make it tough for experts in the coming years, thus expect more from the cryptographic community!
