| Samsung SoC SSS (Security SubSystem) module |
| |
| The SSS module in S5PV210 SoC supports the following: |
| -- Feeder (FeedCtrl) |
| -- Advanced Encryption Standard (AES) |
| -- Data Encryption Standard (DES)/3DES |
| -- Public Key Accelerator (PKA) |
| -- SHA-1/SHA-256/MD5/HMAC (SHA-1/SHA-256/MD5)/PRNG |
| -- PRNG: Pseudo Random Number Generator |
| |
| The SSS module in Exynos4 (Exynos4210) and |
| Exynos5 (Exynos5420 and Exynos5250) SoCs |
| supports the following also: |
| -- ARCFOUR (ARC4) |
| -- True Random Number Generator (TRNG) |
| -- Secure Key Manager |
