However, parameters of BCH codes are unknown in general. In this paper, we investigate parameters of BCH codes of length (frac{q^m+1}{lambda }) where (lambda mid q+1) .Some new techniques are employed to study the coset leaders. For any odd prime power q and (m=4,8) , or (mge 12) and (mequiv 4~ (textrm{mod}~ 8)) , the second, the third and the fourth largest coset leaders modulo (q^m+1) are determined, and the dimensions of some BCH codes of length (q^m+1) with large designed distances are given. For (1<lambda <q+1) , the first few largest coset leaders and the coset leaders modulo (frac{q^m+1}{lambda }) in the range 1 to ( frac{ q^{lfloor (m+1)/2rfloor }}{lambda }) are studied, and the dimensions of some BCH codes of length (frac{q^m+1}{lambda }) are given as well. The BCH codes presented in this paper are LCD codes and have a sharper lower bound on the minimum distance than the well-known BCH bound.","PeriodicalId":10788,"journal":{"name":"Cryptography and Communications","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139580798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A major problem concerning NFSRs is to construct NFSRs with large periods. In this paper, a new NFSR structure whose period could be theoretically analyzed is proposed and studied, called GL-S-NFSR. A GL-S-NFSR is a selective cascade connection of a primitive Galois LFSR into a standard Galois NFSR with a linear simplified feedback function, where standard Galois NFSRs with linear simplified feedback functions are very useful in stream ciphers, e.g., Trivium. It is proved that the periods of the output sequences of a GL-S-NFSR are lower bounded by the product of all the Zsigmondy primes of ( 2^n-1 ) with a probability close to 1 under a weak assumption, and particularly, if n is a prime, then (2^n-1) divides the periods of the output sequences with a high probability, where n is the stage of the Galois LFSR. Besides, it is also proved that there are several registers satisfying that the periods are multiples of Zsigmondy primes without any assumption. Note that the main building block of Kreyvium consists of a standard Galois NFSR with a linear simplified feedback function and two pure cycling registers (PCRs). Periodic results on GL-S-NFSR are applied to Kreyvium by modifying one PCR to a primitive LFSR and the modified building block of Kreyvium is called M-Kreyvium. It is shown that the sequences involved in M-Kreyvium could have large periods with high probabilities.","PeriodicalId":10788,"journal":{"name":"Cryptography and Communications","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139497393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
