RSA is a public-key cryptosystem developed by MIT professors Ronald L. Rivest, Adi Shamir, and Leonard M. Adleman in 1977 in an effort to help ensure Internet security. RSA uses modular arithmetic and elementary number theory to do computations using two very large prime numbers. Identify the statement which is true for RC6 algorithm:. a) Is a variable key-size stream cipher with byte-oriented operations and is based on the use of a random permutation
b) Includes integer multiplication and the use of four 4-bit working registers
c) Is a parameterized algorithm with a variable block size, key size, and a variable number of rounds
d) Is a 64 bit block cipher that uses a key length that can vary between 32 and 448 bits

Problems: 1. using textbooks, reference books, and internet as your source of research, draw the following microprocessor microarchitectures i. intel 8086 ii. motorola 68000 i atmel atmega32 iv. mips single cycle v. arm cortex-m3 write an hdl module for a hexadecimal seven-segment display decoder. the input is 4-bit binary representing a hex number (0-f), and the output is 8-bit seven segment display bits (a-h). thus, the decoder must handle the digits 10 - 15 to display a-f respectively, in addition to 0-9 numbers. 2. design a 4-bit left and right rotator (both outputs). first sketch schematic diagrams of your design. then implement your design using hdl coding. 3. 4. design a modified priority encoder that receives an 8-bit input, a7: 0 and produces a 3-bit output, y2o. y indicates the most significant bit of the input that is true. y should be 0 if none of the inputs are true. give a simplified boolean equation, sketch a schematic, and write an hdl code. 5.write an 8: 1 multiplexer module called mux8 with selection inputs s, data input d, and data output y. data input (d) and data output (v) are 32-bit wide
