Signatures for network coding
DOI: 10.1504/IJICOT.2009.024044 | Denis Charles, Kamal Jain, Kristin Lauter | This paper presents a practical digital signature scheme to be used in conjunction with network coding. Furthermore, the authors| idea simultaneously provides authentication and detects malicious nodes that intentionally corrupt content on ... | 3 - 14 |
On non-existence of perfect and nearly perfect sequences
DOI: 10.1504/IJICOT.2009.024044 | Siu Lun Ma, Wei Shean Ng | We study the complex p-ary perfect and nearly perfect sequences where p is an odd prime and show that the existence of such sequences is equivalent to the existence of certain kinds of difference sets. Using results from difference sets, th... | 15 - 38 |
Bias reduction via linear combination of nearest neighbour entropy estimators
DOI: 10.1504/IJICOT.2009.024044 | Alexei Kaltchenko, Nina Timofeeva | The problem of entropy estimation of stationary ergodic processes is considered. A new family of entropy estimators is constructed as a linear combination of the nearest neighbour estimators with a new metric. The consistency of the new est... | 39 - 56 |
Codes from zero-divisors and units in group rings
DOI: 10.1504/IJICOT.2009.024044 | Paul Hurley, Ted Hurley | A new construction method for codes using encodings from group rings is described and presented. They consist primarily of two types: zero-divisor and unit derived codes. Previous codes from group rings focused on ideals; for example, cycli... | 57 - 87 |
The use of genetic programming for adaptive text compression
DOI: 10.1504/IJICOT.2009.024044 | M. Zaki, M. Sayed | This paper exploits a modified genetic programming (GP) approach for solving the data compression problem. In fact, the typical GP algorithm in which a candidate solution is expressed as a tree rather than a bit string, fails to solve that ... | 88 - 108 |
On the classification of the codes obtained by subtracting from some ternary extremal self-dual codes
DOI: 10.1504/IJICOT.2009.024044 | Naoyuki Horiguchi | The codes obtained from a ternary extremal self-dual [12m,6m,3m+3] code by subtracting T4 on any four distinct coordinates are ternary extremal self-dual [12m - 4,6m - 2,3m] codes for a positive in... | 109 - 118 |
A new class of pseudo-random sequences from Mersenne numbers
DOI: 10.1504/IJICOT.2009.024044 | Abhijit Mitra | A new class of pseudo random sequences is proposed that can be constructed from modulo-2 (mod 2) operations of two different maximal length sequences (m-sequences) where the period of the input sequences are Mersenne numbers. It is shown th... | 119 - 127 |
