Learn about symmetric ciphers.
- [Instructor] In addition to classifying…encryption ciphers into stream and block ciphers,…we can also categorize them as either symmetric…or asymmetric algorithms,…based on the type of key they utilize…to secure their data.…With symmetric encryption, a single key is used…to encrypt and decrypt the data.…With asymmetric encryption, a different key is used…to encrypt the data than to decrypt it.…Symmetric algorithms are often called…private key encryption,…due to the fact that both the sender and the receiver…need to know the shame shared secret…or privately held key.…
Symmetric key is a fairly easy concept to understand.…After all, your house can be locked or unlocked…using the exact same key.…And if you wanted me to be able to unlock your house also,…you'd have to give me an exact copy of your private key,…allowing us to have a shared secret key.…Due to this shared key, confidentiality can be assured,…but non repudiation cannot be.…The challenge with symmetric algorithms, though,…is one of key distribution.…If you wanted to send encrypted emails…
