Mono alphabetic cipher causes difficulty to crack the message as there are random substitutions and a large number of permutation and combination are available. C can be replaced by A, B, and D to z, etc. That is, A can be replaced by any other alphabet from B to Z. In monoalphabetic, each alphabet in plain text can be replaced by any other alphabet except the original alphabet.
Replace each alphabet with a specified number down.Īs Caesar cipher and a modified version of Caesar cipher is easy to break, monoalphabetic cipher comes into the picture. So here, the plain text is EDUCBA, and ciphertext Is FEVDCB.Ī modified version of the Caesar cipher algorithm is as follows. For example, EDUCBA and number for the replacement are 1, so E will replace by F, D will replace by E, U will replace by V, C will replace by D, B will replace by C, and A will replace by B. Repeat the process for all alphabet in plain text.Ī Modified Version of Caesar Cipher: This cipher works the same as Caesar cipher the only difference is – in Caesar cipher, each alphabet is replaced by three-place down wherein a modified version of Caesar cipher, a user decides the number to replace the alphabet, and this number will be constant. Replace each alphabet with 3 places down. So here the plain text is EDUCBA and ciphertext Is HGXFED. As a Caesar cipher, each alphabet is replaced by three-place down so that E will replace by H, D will replace by G, U will replace by X, C will replace by F, B will replace by E, and A will replace by D. In Caesar’s cipher, each alphabet in the message is replaced by three places down. It is a very weak technique of hiding text. In Caesar cipher, the set of plain text characters is replaced by any other character, symbols or numbers. #Ab cipher translator software

If the current value of y or z have no next uses or not live on exit from the block or in register then alter the register descriptor to indicate that after execution of x : = y op z those register will no longer contain y or z.Start Your Free Software Development Course.

If x is in L then update its descriptor and remove x from all other descriptor. Update the address descriptor of x to indicate that x is in location L. if z is in both then prefer a register to a memory location.
Generate the instruction OP z', L where z' is used to show the current location of z. If the value of y is not already in L then generate the instruction MOV y', L to place a copy of y in L. If the value of y currently in memory and register both then prefer the register y'. Consult the address description for y to determine y'. Invoke a function getreg to find out the location L where the result of computation b op c should be stored. 
For each three address statement of the form a:= b op c perform the various actions. The algorithm takes a sequence of three-address statements as input. An address descriptor is used to store the location where current value of the name can be found at run time.The register descriptors show that all the registers are initially empty. A register descriptor contains the track of what is currently in each register.
