Is Java Card ready for hash-based signatures?

Abstract: The current Java Card platform does not seem to allow for fast implementations of hash-based signature schemes. While the underlying implementation of the cryptographic primitives provided by the API can be fast, thanks to implementations in native code or in hardware, the cumulative overhead of the many separate API calls results in prohibitive performance for many common applications. In this work, we present an implementation of \XMSSMT on the current Java Card platform, and make suggestions how to improve this platform in future versions.
