本标准提供了基于格上硬问题的通用公钥密码技术规范，这些硬问题补充了IEEE Std 1363？2000[B47]1和IEEE Std 1363a-2004[B48]中考虑的问题，包括用于秘密值（密钥）推导、公钥加密、识别和数字签名的数学原语，以及基于这些原语的加密方案。还介绍了相关密码参数、公钥和私钥的规范。计算机和通信系统的类别不受限制。

This standard provides specifications of common public key cryptographic techniques based on hard problems over lattices supplemental to those considered in IEEE Std 1363-2000 [B47]1 and IEEE Std 1363a-2004 [B48], 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 are also presented. Class of computer and communications systems is not restricted.
