On the (im)possibility of perennial message recognition protocols without public-key cryptography
Madeline González Muñiz, Peeter Laud · 2011
A message recognition protocol (MRP) aims to exchange authenticated information in an insecure channel. During the initialization session of the protocol, the parties exchange some authenticated information which the adversary can passively observe. Then, one party wants to send authenticated messages to the other party over an insecure channel. Such security requirements are often found in wireless sensor networks.
