**IEEE P1363** is an "Institute of Electrical and Electronics Engineers (IEEE) standardization project for "public-key cryptography. It includes specifications for:

- Traditional public-key cryptography (IEEE Std 1363-2000 and 1363a-2004)
- Lattice-based public-key cryptography (IEEE Std 1363.1-2008)
- Password-based public-key cryptography (IEEE Std 1363.2-2008)
- Identity-based public-key cryptography using pairings (P1363.3)

The chair of the working group as of October 2008 is William Whyte of "NTRU Cryptosystems, Inc., who has served since August 2001. Former chairs were Ari Singer, also of NTRU (1999-2001), and "Burt Kaliski of "RSA Security (1994-1999).

This specification includes key agreement, signature, and encryption schemes using several mathematical approaches: "integer factorization, "discrete logarithm, and "elliptic curve discrete logarithm.

**DL/ECKAS-DH1 and DL/ECKAS-DH2**(Discrete Logarithm/Elliptic Curve Key Agreement Scheme, "Diffie–Hellman version): This includes both traditional "Diffie–Hellman and "elliptic curve Diffie–Hellman.**DL/ECKAS-MQV**(Discrete Logarithm/Elliptic Curve Key Agreement Scheme, "Menezes–Qu–Vanstone version)

**DL/ECSSA**(Discrete Logarithm/Elliptic Curve Signature Scheme with Appendix): Includes four main variants: "DSA, "ECDSA, Nyberg-Rueppel, and Elliptic Curve Nyberg-Rueppel.**IFSSA**(Integer Factorization Signature Scheme with Appendix): Includes two variants of "RSA, Rabin-Williams, and ESIGN, with several message encoding methods. "RSA1 with EMSA3" is essentially PKCS#1 v1.5 RSA signature; "RSA1 with EMSA4 encoding" is essentially "RSA-PSS; "RSA1 with EMSA2 encoding" is essentially ANSI X9.31 RSA signature.**DL/ECSSR**(Discrete Logarithm/Elliptic Curve Signature Scheme with Recovery)**DL/ECSSR-PV**(Discrete Logarithm/Elliptic Curve Signature Scheme with Recovery, Pintsov-Vanstone version)**IFSSR**(Integer Factorization Signature Scheme with Recovery)

**IFES**(Integer Factorization Encryption Scheme): Essentially "RSA encryption with "Optimal Asymmetric Encryption Padding (OAEP).**DL/ECIES**(Discrete Logarithm/Elliptic Curve Integrated Encryption Scheme): Essentially the "DHAES" variant of "ElGamal encryption.**IFES-EPOC**(Integer Factorization Encryption Scheme, EPOC version)

This document includes a number of "password-authenticated key agreement schemes, and a password-authenticated key retrieval scheme.
