Spotted an interesting report recently stating that 768-bit RSA encryption has been broken. Specifically, what researchers have done is factorised a 768=bit 232-digit number using a number field sieve ...
Like the PDP-8, this machine uses a bit-serial ALU, which allows the circuit to be much smaller than the more usual ALU structure, at the expense of needing a clock cycle per bit per operation, i.e. a ...
