In this course we will be studying Algebra and algebraic number theory, with a concentration on the aspects that relate to modern cryptography.
Until recently, most methods of encrypting messages were essentially
a simple matrix multiplication whose security lay in the fact that
the elements of the matrix were unknown.
In the late 1970s, Rivest, Shamir, and Adelman described a technique
that took advantage of the fact that factoring integers is a hard problem.
Their scheme uses the cyclic group generated using modular arithmetic.
More recently, others have invented schemes using Elliptic curves to
make use of groups that have more complicated structure.
