Detailed Description

ELS driver.

This component abstracts the hardware access to the ELS IP. The library exposes the following hardware functionality:

1. COMMON
   • Determine information of the underlying ELS hardware IP
     • #mcuxClEls_GetHwVersion
     • #mcuxClEls_GetHwState
   • ELS enabling, disabling, and software reset
     • #mcuxClEls_Enable_Async
     • #mcuxClEls_Reset_Async
     • #mcuxClEls_Disable
   • Interrupt management
     • #mcuxClEls_SetIntEnableFlags
     • #mcuxClEls_GetIntEnableFlags
     • #mcuxClEls_ResetIntFlags
     • #mcuxClEls_SetIntFlags
   • Wait for completion of an ELS operation
     • #mcuxClEls_WaitForOperation
     • #mcuxClEls_LimitedWaitForOperation
   • Error handling
     • #mcuxClEls_ResetErrorFlags
     • #mcuxClEls_GetErrorCode
     • #mcuxClEls_GetErrorLevel
   • Random delay feature for AES based operations
     • #mcuxClEls_SetRandomStartDelay
     • #mcuxClEls_GetRandomStartDelay
2. CRC
   • Command CRC checks
     • #mcuxClEls_ConfigureCommandCRC
     • #mcuxClEls_GetCommandCRC
     • #mcuxClEls_VerifyVsRefCRC
     • #mcuxClEls_UpdateRefCRC
3. HASH
   • SHA-2 hashing
     • #mcuxClEls_Hash_Async
4. CIPHER (Symmetric Encryption)
   • AES
     • #mcuxClEls_Cipher_Async
5. KEY MANAGEMENT
   • Key import
     • #mcuxClEls_KeyImport_Async
   • Key properties
     • #mcuxClEls_GetKeyProperties
6. ECC (Elliptic Curve Cryptography)
   • ECC Key generation
     • #mcuxClEls_EccKeyGen_Async
   • ECC signature generation
     • #mcuxClEls_EccSign_Async
   • ECC signature verification
     • #mcuxClEls_EccVerify_Async
7. KEY DERIVATION
   • Key derivation

After each call to a function ending in _Async, one of the waiting functions #mcuxClEls_WaitForOperation or #mcuxClEls_LimitedWaitForOperation must be called to ensure completion. The waiting functions may fail, e.g., when the ELS enters an error state.
