1. A method for remote direct memory access, comprising:

  • generating a remote direct memory access packet comprising an opaque data comprising an encrypted stream identifier and a digest, a virtual address, and a payload at a local machine;

    receiving the remote direct memory access packet at a virtual network interface card on the local machine;

    reconstructing a stream identifier by separating the opaque data into the encrypted stream identifier and the digest;

    decrypting the encrypted stream identifier;

    verifying the decrypted stream identifier using the first digest;

    providing the verified stream identifier to a system memory management unit; and

    mapping the virtual address and the provided stream identifier by the system memory management unit to a physical address, into which to write the payload.
