32 / 173 page  Description STM32F21xxx 32/173 Doc ID 17050 Rev 8 2.2.32 Cryptographic acceleration The STM32F215xx and STM32F217xx devices embed a cryptographic accelerator. This cryptographic accelerator provides a set of hardware acceleration for the advanced cryptographic algorithms usually needed to provide confidentiality, authentication, data integrity and non repudiation when exchanging messages with a peer. ● These algorithms consists of: Encryption/Decryption – DES/TDES (data encryption standard/triple data encryption standard): ECB (electronic codebook) and CBC (cipher block chaining) chaining algorithms, 64-, 128- or 192-bit key – AES (advanced encryption standard): ECB, CBC and CTR (counter mode) chaining algorithms, 128, 192 or 256-bit key Universal hash – SHA-1 (secure hash algorithm) –MD5 ● It also provides a true random number generator that deliver 32-bit random numbers produced by an integrated analog circuit. 2.2.33 True random number generator (RNG) All STM32F2xxx products embed a true RNG that delivers 32-bit random numbers produced by an integrated analog circuit. |
