Abstract:

Digital signatures are one of the main application scenarios for modern
cryptography, e.g., for digital certificates on the Internet or banking
cards. The most widely used algorithms for digital signatures, RSA and
Elliptic Curve Digital Signature Algorithm (ECDSA), are computationally
expensive, making them very challenging for many embedded applications
such as smart cards or RFID tags. Hence the need for better methods is
highly visible.
One alternative to RSA and ECDSA is the Merkle signature scheme which
provides digital signatures using hash functions only. Hash functions
are orders of magnitude more efficient than the the number-theoretical
based RSA and elliptic curve schemes. After a general introduction to
hash-based signatures,  the strengths and weaknesses of the Merkle
signature scheme are highlighted.  It will be shown that hash-based
signatures are a promising alternative to the well-established signature
schemes, especially for embedded systems.­
