WebIn 1985 Siegenthaler introduced the concept of correlation attacks on LFSR based stream ciphers. A few years later Meier and Staffelbach demonstrated a special technique, … WebIn this paper, we describe an additive stream ciphering algorithm, called “TWOPRIME≓. It is designed for 32-bit computers, and the key has 128 bits. It is fast in software and analytical in the sense that some security aspects of the algorithm can be controlled. A faster version of TWOPRIME is also presented. We also describe a variant of TWOPRIME, called …

WebAs shown in Fig. 4, the adjacency pixels correlation in the cipher image is sparse D. SENSITIVITY TO SECURITY KEYS and in the input color image is almost linear. As a result, Both encryption and decryption keys thwart incursions by the suggested technique is impenetrable to various attacks. WebIn this paper we propose a new attack on a general model for irregular clocked keystream generators. The model consists of two feedback shift registers of lengths l 1 and l 2, where the first shift register produces a clock control sequence for the second. This model can be used to describe among others the shrinking generator, the step-1/step-2 generator and … didn\u0027t have offer accepted home options
