The implementation of the TEA symmetric encryption algorithm given in Figure 11.8–11.10. is not
portable between all machine architectures. Explain why. How could a message encrypted using
the TEA implementation be transmitted to decrypt it correctly on all other architectures?

Byte ordering is an issue. The algorithm as presented assumes that the 4 bytes in a 32-bit word are ordered the
same at the sender (encrypter) and the receiver (decrypter). To make it work for all architectures, we would
need to transmit messages in a network-standard byte order, and to re-order the bytes to suite the local
architecture on receipt.
