This problem provides a numerical example of encryption using a one-round versionof DES. We start with the same bit pattern for the key and plain text, namely, In hexadecimal notation 0 1 2 3 4 5 6 7 8 9 A B C D E FInbinary notation: 0000 0001 0010 0011 0100 0101 010 1001 1010 1011 1100 1101 1110 1111(a) Derive K1, the first – round subkey.(b) Derive L0,R0(c) Expand R0 to get ER0(d) Calculate A=ER0 K1.(e) Group the 48-bit result of (d) into sets of 6 bits and evaluate the correspondingS-box substitutions.(f) Cancatenate the results of (e) to get a 32-bit result,B.(g) Apply the permutation to get P(B).(h) Calculate R1=P(B) L0(i) write down the cipher text.2.
(a) List the characteristics of advanced block ciphers.(b) What are the differences between RC5 and RC2?3. (a) What are two different uses of public – key cryptography related to key Distribution?(b) Explain RSA Algorithm?4. (a) Explain in detail about Euclid’s Algorithm.(b) Determine gcd(1970,1066).5. (a) What is a difference between little-endian and big-endian format?(b) What basic arithmetical and logical functions are used in MD5?6. (a) List limitations of SMTP/822 scheme?(b) What are the MIME specifications?7. (a) What are the basic approaches to building SAs?(b) What are the roles of the Oakley key determination protocol and ISAKMP in IPSec?8.
(a) what information used by a typical packet-filtering router?(b) What are some weaknesses of a packet-filtering router?(c) What is the difference between a packet-filtering router and a stateful inspection firewall?

In this new first edition, well-known author Behrouz Forouzan uses his accessible writing style and visual approach to simplify the difficult concepts of cryptography and network security.
This edition also provides a website that includes Powerpoint files as well as instructor and students solutions manuals. Forouzan presents difficult security topics from the ground up.
A gentle introduction to the fundamentals of number theory is provided in the opening chapters, paving the way for the student to move on to more complex security and cryptography topics. Difficult math concepts are organized in appendices at the end of each chapter so that students can first learn the principles, then apply the technical background. Hundreds of examples, as well as fully coded programs, round out a practical, hands-on approach which encourages students to test the material they are learning.
