#165612 - Do you really mean "encryption"?
Responding to: ???'s previous message
Amor Leo Ricaborda said:
or any better/common method to check if the UART data is corrupted

If you only need to check if the data is corrupted, then you don't need encryption at all.

I think the commonest methods must be either a sinmple checksum or, if that's not sufficient, a CRC

CRCs are certainly perfectly feasible on an 8051, and suitable for UART comms - and plenty of readyt-to-use implementations are widely available.
