Three Lessons From Threema: Analysis of a Secure Messenger

WebIn the context of new threats to Public Key Cryptography arising from a growing computational power both in classic and in quantum worlds, we present a new group law defined on a subset of the projective plane F P 2 over an arbitrary field F , which lends itself to applications in Public Key Cryptography and turns out to be more efficient in terms of … Group-based cryptography is a use of groups to construct cryptographic primitives. A group is a very general algebraic object and most cryptographic schemes use groups in some way. In particular Diffie–Hellman key exchange uses finite cyclic groups. So the term group-based cryptography refers mostly to cryptographic protocols that use infinite nonabelian groups such as a braid group.

"Webthe cryptographic group that is employed in protocols is a large prime-order subgroup of the group E(F p) of F p-rational points on E. The group of rational points consists of all solutions (x;y) 2F2 p to the curve equation together with a point at in nity, the neutral element. The number of F p-rational points is denoted by #E(F " - Cryptographic groups

Before the modern era, cryptography focused on message confidentiality (i.e., encryption)—conversion of messages from a comprehensible form into an incomprehensible one and back again at the other end, rendering it unreadable by interceptors or eavesdroppers without secret knowledge (namely the key needed for decryption of that message).

WebClasses of Cryptographic Algorithms There are three general classes of NIST-approved cryptographic algorithms, which are defined by the number or types of cryptographic keys that are used with each. Hash functions A cryptographic hash function does not use keys for its basic operation. WebJan 25, 2024 · 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 Shor’s algorithm, while still having a number of applications. The most famous example of group actions are built from isogenies on elliptic curves.
