P1363 is the IEEE working group that is developing standards for public-key cryptography based on RSA (see Question 8), Diffie-Hellman (see Question 24), and related algorithms. The scope of the standards includes encryption algorithms such as RSA, Diffie-Hellman, ElGamal (see Question 29), and elliptic curve cryptosystems (see Question 31), as well as random number generation and hardware support. A first version of the standard covers elliptic curve cryptosystems and is nearly complete.
