06 In cryptography, the encryption algorithm E and the decryption algorithm D must meet the following conditions to ensure that plaintext P can be securely encrypted and correctly restored! Network Technology Section 1) Reversibility Condition The encryption and decryption must be inverse operations of each other, that is: D(E(P))=PExplanation: Applying the encryption algorithm E to … Read more
Encryption and Asymmetric Encryption Symmetric encryption: The same key is used for both encryption and decryption, such as the AES algorithm.Asymmetric encryption: Uses a pair of keys (public key + private key), where the public key is used for encryption and the private key is used for decryption. RSA is a typical representative. RSA Algorithm … Read more
Head-of-Line Blocking in HTTP/2 Although HTTP/2 uses “frames”, “streams”, and “multiplexing” to eliminate “head-of-line blocking”, these techniques are applied at the application layer. However, at the lower layer, specifically in the TCP protocol, “head-of-line blocking” can still occur. TCP has a special “packet retransmission” mechanism to ensure reliable transmission. Lost packets must wait for retransmission … Read more
