A sequence of new pseudorandom number generators are developed: IA, IBAA, and ISAAC. No efficient method is known for deducing their internal states. ISAAC requires an amortized 18.75 instructions to produce a 32-bit value. There are no cycles in ISAAC shorter than 240 values. The expected cycle length is 28295 values. Tests show that scaled-down versions of IBAA are unbiased for their entire cycle length. No proofs of security are given.
