Turing is a stream cipher developed by Gregory G. Rose and Philip Hawkes at Qualcomm for CDMA.
[1] Turing generates 160 bits of output in each round by applying a non-linear filter to the internal state of an LFSR.
[2] This is evident in its major component, the Linear Feedback Shift Register (LFSR), which is the same technology found in the family of SOBER machines.
[3] Turing, however, is distinguished from its predecessors by the way it produces five words (five times more) of output for every internal update.
There are experts who found that the Turing stream cipher has a number of weaknesses when faced with chosen IV attacks.
