Purpose and Scope of IEEE P1363.1

P1363.1: Standard Specification for Public-Key Cryptographic Techniques Based on Hard Problems over Lattices


Specifications of common public-key cryptographic techniques based on hard problems over lattices supplemental to those considered in IEEE 1363 and IEEE P1363a, including mathematical primitives for secret value (key) derivation, public-key encryption, identification and digital signatures, and cryptographic schemes based on those primitives. Specifications of related cryptographic parameters, public keys and private keys. Class of computer and communications systems is not restricted.


The transition from paper to electronic media brings with it the need for electronic privacy and authenticity. Public-key cryptography offers fundamental technology addressing this need. Many alternative public-key techniques have been proposed, each with its own benefits. The IEEE 1363 Standard and P1363a project have produced a comprehensive reference defining a range of common public-key techniques covering key agreement, public-key encryption and digital signatures from several families, namely the discrete logarithm, integer factorization, and elliptic curve families. IEEE P1363.1 will specify cryptographic techniques based on hard problems over lattices. These techniques may offer tradeoffs in operating characteristics when compared with the methods already specified in IEEE 1363-2000 and draft P1363a. It is also intended that P1363.1 provide a second-generation framework for the description of cryptographic techniques, as compared to the initial framework provided in 1363-2000 and draft P1363a. It is not the purpose of this project to mandate any particular set of public-key techniques or security requirements (including key sizes) for this or any family. Rather, the purpose is to provide: (1) a reference for specification of a variety of techniques from which applications may select, (2) the relevant number-theoretic background, and (3) extensive discussion of security and implementation considerations so that a solution provider can choose appropriate security requirements for itself.
