Expand the idea of a bit-based stream cipher as discussed in Definition 2.1.1. in the text book to an alphabet of 29 letters as in the German language. Here, the additional letters are ä, ö and ü. Now, develop a stream cipher that uses those 29 letters, instead of bits. What does the key stream look like? Remember that in bit-based stream ciphers, the elements in the stream are members of Ring Z2What do the encryption and decryption functions look like?Encrypt the message: "an alphabet with twenty nine letters is weird". Use the very same text as the key for encryption.

The instruction ishl (shift left integer) exists in jvm but not in ijvm. it uses the top two values on the stack, replacing the two with a single value, the result. the sec- ond-from-top word of the stack is the operand to be shifted. its content is shifted left by a value between 0 and 31, inclusive, depending on the value of the 5 least signifi- cant bits of the top word on the stack (the other 27 bits of the top word are ignored). zeros are shifted in from the right for as many bits as the shift count. the opcode for ishl is 120 (0x78).a. what is the arithmetic operation equivalent to shifting left with a count of 2? b. extend the microcode to include this instruction as a part of ijv.

Idon’t understand the double8 coding problem. it is java

Amitha writes up a one-page summary of a novel during her summer internship at a publishing company. when she reads over the page, she realizes she used the word “foreshadow” seven times, and she would like to reduce the repetition. which tool would best amitha solve this problem?
