An upstart in the field of cryptography has proposed a new definition for perfect security of private$-$key encryption schemes. According to this new definition, a private$-$key encryption scheme $($Gen$,$ Enc, Dec$)$ is perfectly secure if$,$ for all apriori distribution M over the message space, and any two cipher$-$ texts c and c$,$ we have the following identity. P $[$C $=$ c$]=$ P $[$C $=$ c$]$ Show that the definition in the class does not imply this new definition. Remark. You need to construct a private$-$key encryption scheme that is secure according to the definition we learned in class. However, this scheme does not satisfy the new definition.
