Question: Let F be a secure PRP with blocklength . Consider the following encryption algorithm: Enc(k,m): r:{0,1}x:=(k,m)rreturn(r,x) Show that the scheme does not satisfy CPAS security.

Let F be a secure PRP with blocklength . Consider the following encryption algorithm: Enc(k,m): r:{0,1}x:=(k,m)rreturn(r,x) Show that the scheme does not satisfy CPAS security. 1. Clearly write the code for a distinguisher/calling program. 2. Clearly state the relevant output probabilities. For reference, here is the definition of CPA\$ security: k.KeyGenc.Creturncreturnc
