Elliptic Curve Cryptography has gained momentum in application recently because
Elliptic Curve Cryptography has gained momentum in application recently because of the relatively smaller key size to achieve the same level of security using another asymmetrical algorithm like RSA. For example, a key size of 3072 in RSA has the same strength as an ECC key size of 256. In this paper, you are going…

TASK 1 (15 points): Superencrypt “Abstractionism” by using keywords “Painter” for the ADFGVX substitution and “Kandinsky” for the transposition matrix. TASK 2 (3 points): Please encrypt Claude Shannon’s quote by using the given key: “Information is the resolution of uncertainty” Given key: n+2, n-1, n+1, n-2 Example: You will encrypt the word “Hello” by using…

Hashing is a one-way function that maps a message to a fixed-size sequence of bits (hashed value) with the assumption it is extremely difficult to reverse the process. Given the hashed-value, it is practically impossible to compute the original message given the hashed-value. It is extremely rare that two messages hash to the same value.…

The hash value of a message is a one-way “unique value” that can be extracted from the message using algorithms like MD5 and SHA-x. In this paper, you are going to use a hash calculator (the best way to find one is to google hash calculator). Cut and paste the message below into a hash…
