Analysis Of A Sieving Heuristic For The Number Field Sieve And Design Of Low-Correlation CDMA Sequences
(2011-01-25)
In this thesis, we investigate in detail, certain important problems in cryptography and coding theory.
In the first part of this thesis, we discuss the number field sieve and compare the two ways in which the sieving ...
Low-PAPR, Low-delay, High-Rate Space-Time Block Codes From Orthogonal Designs
(2011-02-03)
It is well known that communication systems employing multiple transmit and multiple receive antennas provide high data rates along with increased reliability. Some of the design criteria of the space-time block codes ...

Guessing And Compression : A Large Deviations Approach
(2011-04-01)
The problem of guessing a random string is studied. It arises in the analysis of the strength of secret-key cryptosystems against guessing attacks. Expected number of guesses, or more generally moments of the number of ...
