Blockchain and IoT are being deployed at a large scale in various fields including
healthcare for applications such as secure storage, transactions, and process automation …

The Internet of Things (IoT) provides transparent and seamless incorporation of
heterogeneous and different end systems. It has been widely used in many applications …

Myasnikov (City College of New York) et al. apply the complexity of non-commutative groups
to public key cryptography, assess the generic-case performance of various algorithms, and …

We revisit the ordinary isogeny-graph based cryptosystems of Couveignes and Rostovtsev–
Stolbunov, long dismissed as impractical. We give algorithmic improvements that accelerate …

This book is about relations between three di? erent areas of mathematics and
theoreticalcomputer science: combinatorialgroup theory, cryptography, and c-plexity theory …

A natural, but slowly emerging program. In his PhD thesis prepared under the supervision of
Graham Higman and defended in 1965 [123], and in the article that followed [124], FA …

Publisher Summary Crossings are suggested as they are in a picture of a highway overpass
on a map. The identity braid has a canonical representation in which two strands never …

Cryptographic group actions are a relaxation of standard cryptographic groups that have
less structure. This lack of structure allows them to be plausibly quantum resistant despite …

A generalization of the original Diffie-Hellman key exchange in $(\Z/p\Z)^* $ found a new
depth when Miller and Koblitz suggested that such a protocol could be used with the group …

Recently, several public key exchange protocols based on symbolic computation in non-
commutative (semi) groups were proposed as a more efficient alternative to well established …
