WebThe development of public key cryptography was motivated by the requirement to find solutions to two fundamental problems, the first of which is key delivery. Give a concise illustration of how the distribution of keys can be carried out by using an example as a guide. WebQ. Trends in Cryptographic Algorithms for Network providers . Some popular trends in cryptographic algorithms for network providers are symmetric-key cryptography, public-key cryptography, and digital signatures. Symmetric-key encryption is used to protect data against unauthorized access by the provider's employees or other third parties.

WebFor the encryption algorithms, the symmetric cryptosystem uses AES-128, AES-192, and AES-256. The encryption process is generally faster in symmetric cryptosystems due to the smaller key lengths. The drawback of this system is that the senders and receivers need to exchange keys before decrypting the message. WebPoint-01: In symmetric key cryptography, Both sender and receiver uses the same key. Sender encrypts the message using his copy of the key. Receiver decrypts the message using his copy of the key.
