Description
Q1: Survey on Differential Cryptanalsys (DC) and Linear Cryptanalsys.
DC and LC are the two most essential cryptanalysis methods for block ciphers. Your task is to review articles about DC and LC available on the Internet and write a survey report about DC and LC. The length of your report should be 1500‐1600 words, excluding references and tables. Your report should cover DC and LC almost equally, say, 800 words for both DC and LC if your report contains 1600 words.
Q2: Building ElGamal Hybrid Encryption Scheme Using Java
Your task is to write a Java program for the ElGamal hybrid encryption scheme. A hybrid
encryption scheme combines public key encryption and symmetric encryption so that it can
encrypt a long message. The original ElGamal encryption scheme (we learnt in the lecture)
can only encrypt a “small” number, an element of the subgroup of ܼ
∗. To encrypt a long
message, we should use a hybrid encryption version of it, which combines the ElGamal
encryption (public key scheme) with AES encryption scheme as follows:
