Figure 6.10. Use of Triple DES in CBC Mode
| 6.1 You want to build a hardware device to do block encryption in the cipher block chaining (CBC) mode using an algorithm stronger than DES. 3DES is a good candidate. Figure 6.10 shows two possibilities, both of which follow from the definition of CBC. Which of the two would you choose: a. For security? For performance? Figure 6.10.
