Asymmetric public key.

The private key P is encrypted (by user A) with the public key Bp using an asymmetric algorithm obtaining PBp. A calculates the hash H1 to M and encrypts the H1 with its secret key As using an asymmetric algorithm obtaining H1As. Then A sends Mp, PBp and H1As to B. B decrypts PBp with his private key Bs, using an asymmetric algorithm obtaining P.
