Imagine about a lock on postbag, which opens with two keys.
Private key, which is personal key and only person, to whom is allotted, have access to it.
Public key, to which public has access / is being notified.
Sender is allotted with two keys:
Key 1 private
Kay 2 public
Receiver is allotted with two keys:
Key 12 private
Key 22 public
Sender will lock postbag Key 1 (his private key) and Key 22 (public key of receiver).
Receiver will open lock with Key 12 (his private key) and key 2 (public key of sender).
Since sender is locking with his private key, he can not deny that message belongs to him.
Since receiver is opening lock with his private key, he can not deny that message is received by somebody else.
