¿µ¹®³»¿ë¿ä¾à The standard provides a functional model for DRBG and discusses the major components of a DRBG mechanism. Furthermore, the standard specifies major functions of the DRBG mechanism, CTR_DRBG, using a secure block cipher as the base primitive. As a reference, the standard offers numerical examples of CTR_DRBG using Korean standard block ciphers SEED, ARIA, HIGHT, and LEA.
