Clock Control OUTPUT SHIFT DIRECTION

چکیده
This paper shows how a well-balanced trade-oo between a generic workstation and dumb but fast reconngurable hardware can lead to a more eecient implementation of a cryptanalysis than a full hardware or a full software implementation. A realistic cryptanalysis of the A5/1 GSM stream cipher is presented as an illustration of such trade-oo. We mention that our cryptanalysis requires only a minimal amount of cipher output and cannot be compared to the attack recently announced by Alex Biryukov, Adi Shamir and David Wagnerr2].

A Note On Sequences Generated by Clock Controlled Shift Registers
I n this paper the l inear feedback shif t registers are determined that can generate the output sequence o f two types o f clock controlled shift registers suggested by P. Nyffeler. For one type of clock control sufficient conditions are given which guarantee that maximum linear complexity is obtained. Furthermore, it i s shown that the randomness properties for sequences o f maximal linear co...
متن کاملLow-Dropout Regulator with Tri-Loop Control
Low-dropout regulators (LDOs) are widely distributed in SoC designs to supply individual voltage domains, and a digital LDO (DLDO) is favorable for its lowvoltage operation and process scalability. However, as many SoCs generate a load current (ILOAD) variation at sub-A/ns level, voltage regulators require a large areaconsuming output capacitor (COUT) to maintain the output voltage (VOUT) durin...
متن کاملCircuit model for slotline-to-coplanar waveguide asymmetrical transitions - Electronics Letters
When the control unit detects the diagnose input sequence, it sets the DCR (p, = 1 for all 0, and drives the architecture to the DTM by setting NIT = 0 and TID = 0. This switches the MUX driving To,, to the DCR output therefore driving the external output to a logic 1, to signal that the device is in DTM (see Fig. 2). The control unit then sets the DCR to the shift mode, starting a partition id...
متن کاملTracking clock-shifted homing pigeons from familiar release sites.
Clock-shifted homing pigeons were tracked from familiar sites 17.1 km and 23.5 km from the home loft in Pisa, Italy, using an on-board route recorder. At the first release site, north of home, the majority of clock-shifted birds had relatively straight tracks comparable with those of control birds. At the second release site, south of home, the clock-shifted birds deflected in the direction pre...
متن کاملHigh Speed Delay-Locked Loop for Multiple Clock Phase Generation
In this paper, a high speed delay-locked loop (DLL) architecture ispresented which can be employed in high frequency applications. In order to design the new architecture, a new mixed structure is presented for phase detector (PD) and charge pump (CP) which canbe triggered by double edges of the input signals. In addition, the blind zone is removed due to the elimination of reset signal. Theref...
