I have a question

Assume that we have two end-host A and B connected by two routers R1 and R2. A wants to send a large file to B.

  1. A decides to establish ssh connection with host B using public key authentication. Can router R1 or R2 inject content in TCP flow without loosing any original packet sent from A to B?

    A decides to establish SSH connection with host B using public key authentication. Can router R1 or R2 inject content in TCP flow without losing any original packet sent from A to B?

  2. Host A decides to use SSL. Assume A, B R1 and R2 are assigned public/private key with corresponding certificates signed by a certification authority(CA). All nodes know public key of CA. Can router R1 or R2 inject content in TCP flow without loosing any original packet sent from A to B?

    Host A decides to use SSL. Assume A, B R1 and R2 are assigned public/private key with corresponding certificates signed by a certification authority(CA). All nodes know public key of CA. Can router R1 or R2 inject content in TCP flow without losing any original packet sent from A to B?

Thanks in advance.
