Briefly explain how modern, hybrid cryptosystems use a combination of symmetric and asymmetric encryption for secure communication.
Homework Answers
Hybrid cryptosystems use a combination of symmetric and
asymmetric encryption for a faster encryption of messages.
It starts with an asymmetric key exchange, here a random session
key is generated by one party which is the initiator. A public is
obtained through a digital certificate and is encrypted with a one
time session key. The encrypted session key is transmitted and the
receiver decrypts the session key using their private key. Then an
encrypted verification message is sent for confirmation. Symmetric
encryption is used to exchange data in a faster way using shared
secret session key and is discarded when the session is over.

Exercise 3.2 (Symmetric and Asymmetric Encryption) t In this exercise, you will send an encrypted message from a socket client to a socket server. The message will be encrypted using AES symmetric encryption algorithm in the client. The server receives this ciphertext and decrypt it using the same symmetric key. Before communication over symmetric encryption, you need to first securely distribute the symmetric key between sender and receiver. You can use asymmetric encryption to help distribute the symmetric key. The...

Symmetric key encryption. Suppose (KeyGen,Enc,Dec) is an IND-CPA secure symmetric key en- cryption. We define following new encryption algorithms, are the new schemes still IND-CPA secure? If yes, briefly explain why. If you think it insecure, give an explicit attack violating the IND-CPA definition. Recall that the intuition of IND-CPA security means the ciphertext does not leak any non-trivial information about the plaintext. Enc1(k,m) is defined as follows: It runs Enc(k,m) and obtains c0; then it adds a fixed padding...

Hybrid encryption combines the convenience of a public-key cryptosystem with the efficiency of a symmetric-key cryptosystem and it is used in both TLS and SSL. Say we have the secured RSA and AES available, show how to use hybrid encryption to encrypt a message m= m1m2m3m4m5 with 640 bits without a pre-shared secret between Jane and Karl. Show explanation with a diagram.
