|Title:||On employment of LFSRs over GF(q) in certain stream ciphers||Journal:||IEEE International Symposium on Information Theory - Proceedings||First page:||210||Issue Date:||1-Jan-2002||ISSN:||2157-8095||DOI:||10.1109/ISIT.2002.1023482||Abstract:||
The possibility for malicious selection of LFSRs feedback polynomials in order to install a trap-door for the cryptanalysis was investigated. A design criteria for employment of LFSRs in nonlinear combination keystream generators for stream ciphers was proposed. The criterion required checking of the pattern distribution in a sequence of successive powers of the LFSR state transition matrix.
