11.1 The high-speed transport protocol XTP (Xpress Transfer Protocol) uses a 32-bit
checksum function defined as the concatenation of two 16-bit functions: XOR and
RXOR, defined in Section 11.4 as “two simple hash functions” and illustrated in
Figure 11.4.
a. Will this checksum detect all errors caused by an odd number of error bits?
Explain.
b. Will this checksum detect all errors caused by an even number of error bits? If
not, characterize the error patterns that will cause the checksum to fail.
c. Comment on the effectiveness of this function for use as a hash function for
authentication.
