A brief history of RSA encryption algorithms RSA was presented in 1977 by Ronald Leevist (Ron rivest), Adi Samor (Adi Shamir) and Lennard Adman (Leonard Adleman). All three of them were working at MIT. RSA is the beginning of their three-person

2 positive Powers-2, 4, 8, 16, 32, 64, 128, 256, ...-at the end of the numbers follow an obvious rule: 2, 4, 8, 6, 2, 4, 8, 6, .... These 4 numbers are always going to loop. In addition to the last number there is a loop-actually the final m bit-a

The previous section said 16-bit Timer 1, this section is about 8-bit timer 3 and timer 4!1. OverviewTimer 3 and Timer 4 are two 8-bit timers (8-bit timers). Each timer has a dual independent capture/compare channels (separate capture/compare
