The coded message that follows is an encrypted message from Brutus to the Roman Senate. It was produced using the Caesar cipher method, in which each letter is shifted by a fixed number of places (determined by the key value).OHWV GR MXOLXV RQ PRQGDB PDUFK 48GUHVV: WRJD FDVXDO (EBRG)Required Determine the key used to produce the coded message and decode it.
A digital signaturea. is the encrypted mathematical value of the message sender’s name.b. is derived from the digest of a document that has been encrypted with the sender’s private key.c. is derived from the digest of a document that has been encrypted with the sender’s public key.d. is the computed digest of the sender’s digital certificate.e. allows digital messages to be sent over an analog telephone line.
The systems programmer uses a hashing algorithm to determine storage addresses. The hashing structure is 9,997/key. The resulting number is then used to locate the record. The first two digits after the decimal point represent the cylinder number, while the second two digits represent the surface number. The fifth, sixth, and seventh digits after the decimal point represent therecord number. This algorithm results in a unique address 99 percent of the time. What happens the remainder of the time when the results of the algorithm are not unique? Explain in detail the storage process when key value 3 is processed first, key value 2307 at a later date, and shortly thereafter key value 39.
