1. A computer-implemented method comprising:

  • receiving, by a host computing system configured to host one or more virtual computing nodes of a virtual network and from a mapping server for the virtual network that maintains mapping information associating virtual network addresses of the virtual network with physical network addresses, a cryptographic key;

    receiving, by the configured host computing system, a communication from a first of the virtual computing nodes that is intended for a destination virtual computing node in the virtual network other than the first virtual computing node;

    generating, by the configured host computing system based at least in part on the communication and on the cryptographic key received from the mapping server, a hash value for the communication; and

    forwarding, by the configured host computing system and based at least in part on the mapping information maintained by the mapping server, the communication and the generated hash value to the destination virtual computing node.
