(1 point) Note: The notation from this problem is from Understanding Cryptography by Paar and Pelzl. Suppose you have an LFSR with 6 state bits. The first 12 bits of output produced by this LFSA are 001101100111=s0s1s2s3s4s5s6s7s8s9s10s11. The first bit produced is the leftmost bit and the bit most recently produced is the rightmost bit. a) What is the initial state of the LFSR? Please enter your answer as unspaced binary digits (e.g. 010101 to represent s5=0,s4=1,s3=0,s2=1,s1=0,s0=1). b) What are the tap bits of the LFSR? Please enter your answer as unspaced binary digits (e.g. 010101 to ropresent ps=0,p4=1,p3=0,p2=1,p1=0,p0=1). (1 point) Suppose you have an LFSR with state bits (also known as the seed) (s5,s4,s3,s2,s1,s0)=(1,1,1,0,1,0) and tap bits (also known as feedback coetficients (p5,p4,p3,p2,p1,p0)=(1,1,0,1,0,1). What are the first 12 bits output by this LFSR? Please enter your answer in the form of unspaced binary digits (e.9.010101010101). These come in order s0s1s2s11. (1 point) Note: The notation from this problem is from Understanding Cryptography by Paar and Pelzl. We conduct a known-plaintext attack against an LFSR. Through trial and error we have determined that the number of states is m=4. The plaintext given by 01000111=x0x1x2x3x4x5x6x7 When encrypted by the LFSR produced the ciphertext 10000000=y0y1y2y3y3y5y6y7. What are the tap bits of the LFSR? Please enter your answer as unspaced binary digits (e.g.0101 to represent p3=0,p2=1,p1=0,p0=1 )
