Security issues play an important role in almost all modern communication
and computer networks. As Internet applications continue to grow
dramatically, security requirements have to be strengthened. Hyperelliptic
curve cryptosystems (HECC) allow for shorter operands at the same level of
security than other public-key cryptosystems, such as RSA or
Diffie-Hellman. These shorter operands appear promising for many
applications.

Hyperelliptic curves are a generalization of elliptic curves and they can
also be used for building discrete logarithm public-key schemes. This
thesis approaches to a hardware implementation of a crypto engine based on
hyperelliptic curves. A major part of this work is the development of
computer architectures for the different algorithms needed for HECC. The
architectures are developed for a reconfigurable platform based on Field
Programmable Gate Arrays (FPGAs). FPGAs combine the flexibility of
software solutions with the security of traditional hardware
implementations. In particular, it is possible to easily change all
algorithm parameters such as curve coefficients and underlying finite
field.

In this work we first summarized the theoretical background of
hyperelliptic curve cryptosystems. In order to realize the operation
addition and doubling on the Jacobian, we implemented composition and
reduction algorithms in hardware. These in turn are based on
arithmetic for arithmetic in the underlying field and for arithmetic
in the polynomial ring. The architectures are described in VHDL (VHSIC
Hardware Description Language) and mapped to Xilinx FPGA devices. An
Architecture of a HECC over GF(2^41) was implemented.
