CAB340 - CRYPTOGRAPHY FINAL EXAM 2024 WITH ALL SCORED A+ SOLUTIONS!!

Distinguish between symmetric-key and asymmetric-key cryptosystems. - ANSWER - Aysmmetric key cryptography utilizes two separate keys, a public and a private key, as opposed to symmetric key cryptography, which only utilizes one key. While encryption and decryption in symmetric key cryptography is based on substitutions and permutations of symbols, encryption in asymmetric key cryptography is based off of applying mathematical functions to numbers. Distinguish between public and private keys...

What is Kerberos? - For authentication of users and services on distributed systems What are the 3 servers involved in Kerberos and what do they provide to the user? - KAS - issues a TGT to help communicate with TGS TGS - issues a ST to help log into remote server Server- C can login to S using an account on KAS What does WEP provide? - Login authentication, message confidentiality/integrity/authentication for 802.11 WEP Login Process - - AP sends 128-bit challenge in plaintext - Client ...

Symmetric cipher - A single key is used for both encryption and decryption and is only known by the sender and receiver. Asymmetric cipher - Separate but related keys are used for encryption and decryption. Each person has a public and private key. Security model - What resources the adversary has available and what they are trying to achieve. Adversarial powers - Their computational capability, access to various inputs and outputs of the system and their access to oracles. Adversarial go...
