3 Functional Description
3.9.8 RSA Accelrator
The RSA Accelerator provides hardware support for high precision computation used in various RSA asymmetric
cipher algorithms. The RSA Accelerator in ESP32-S3 supports the following features:
• Large-number modular exponentiation with two optional acceleration options
• Large-number modular multiplication
• Large-number multiplication
• Operands of different lengths
• Interrupt on completion of computation
For more information, please refer to Chapter RSA Accelrator (RSA) in ESP32-S3 Technical Reference
Manual.
3.9.9 Random Number Generator
The random number generator in ESP32-S3 generates true random numbers, which means random number
generated from a physical process, rather than by means of an algorithm. No number generated within the
specified range is more or less likely to appear than any other number.
For more information, please refer to Chapter Random Number Generator (RNG) in ESP32-S3 Technical
Reference Manual.
