Elliptic Curve CryptoWe discuss analogs based on elliptic curves over finite
fields of public key cryptosystems which use the multiplicative group of a
finite field. These elliptic curve cryptosystems may be more secure, because the
analog of the discrete logarithm problem on elliptic curves is likely to be
harder than the classical discrete logarithm problem, especially over GF(2"). We
discuss the question of primitive points on an elliptic curve modulo p, and give
a theorem on nonsmoothness of the order of the cyclic subgroup generated by a
global point.

The earliest public key cryptosystems using number theory were based on the
structure either of the multiplicative group (Z/NZ)* or the multiplicative group
of a finite field G¥(q), q = p". The subsequent construction of analogous
systems based on other finite Abelian groups, together with H. W. Lenstra's
success in using elliptic curves for integer factorization, make it natural to
study the possibility of public key cryptography based on the structure of the
group of points of an elliptic curve over a large finite field. We first briefly
recall the facts we need about such elliptic curves (for more details, see [4]
or [5]). We then describe elliptic curve analogs of the Massey-Omura and ElGamal
systems. We give some concrete examples, discuss the question of primitive
points, and conclude with a theorem concerning the probability that the order of
a cyclic subgroup is nonsmooth. I would like to thank A. Odlyzko for valuable
discussions and correspondence, and for sending me a preprint by V. S. Miller,
who independently arrived at some similar ideas about elliptic curves and
cryptograph

SKIFF IN THE NEWS

Encryption Bans . . . What Is This, Russia?Many in the U.S., U.K. and Australia
would like to force companies like mine to add backdoors giving access to both
law enforcement and hackers.

Andrew Milich
Skiff Mail is taking on Gmail by betting on privacy – and crypto.Now, it’s
coming for Gmail. The company is launching an email service called Skiff Mail
that aims to be, well, encrypted Gmail — and eventually much more than that.

David Pierce
Skiff Wants You To Sign Out Of Google Workspace ForeverSkiff is taking a big
step toward becoming a more private and secure replacement for the G-suite by
adding end-to-end encrypted Calendar and Drive products to its suite.

The Best Email Encryption Services for 2023You don’t have to pay a thing to use
Skiff for end-to-end encrypted email, file sharing, and collaboration. It’s also
very easy to use, but includes advanced features for the technically inclined.
