Knowing b1, we find b2 such that b2 = b1 \oplus s; Knowing b2, we find b1 such that b1 = b1 \oplus s. Do you mean, b1 = b2 \oplus s in the second bullet?

Knowing b1, we find b2 such that b2 = b1 \oplus s;
Knowing b2, we find b1 such that b1 = b1 \oplus s.
Do you mean, b1 = b2 \oplus s in the second bullet? I also cannot follow the example right below it: XOR s5 and s6 gives b3, not b4.
Can someone help me with this?
- spriteware 8y agoYou're right for b1 = b2 xor s in the second bullet, I corrected it. You cannot solve b3 before you solve s2. b4 is solved with s6 right after that you realize that s1 = b1, and thus s6 = b1 xor b4
