Tabella Crittografica

In base alla conoscenze
acquisite sui cifrari
monoalfabetici si dovrà
crittoanalizzare la seguente
tavola cifrata.
Il candidato dovrà usare la
tecnica dell’analisi della
frequenza delle lettere, oltre
ad una analisi sul singolo
carattere alfabetico si
prendano in considerazione
le ripetizioni consecutive, i
bigrammi, infatti le doppie
formano casi particolari.
Un occhio attento e ben
esercitato può contare
anche sull’uso dei
trigrammi.
In ultima analisi il
candidato può fare uso
della Brute Force (forza
bruta)

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.
