It also includes, in the case of a
single mix, what y will use as the first block of the item it submits
to the mix:
A1: [K<A1>( R<A1>, Ax )], [M1], ..., [M<
l-1>] -->
Ax: [R<A1>( M1 )], ..., [R<A1>( M<
l-1> )], [R<A1>( J<A1> )],
where Kx( R0, M ) = M1, M2, ..., M<
l-n>. Only x can decrypt the item
it receives since it created R<A1> and Kx.
