AEAD decryption is failing

Hi team, Good day.

I have 8 bytes of data. I'm using psa_aead_encrypt to encrypt the data and psa_aead_decrypt function to decrypt the data. 

After performing encryption (using AES 128 key, so after encryption my data will become 16 bytes) and I'm sending that data as 2 CAN frames.

After receiving 2 frames(16 bytes) of data even though the data content is equal decryption is failing. Could you please help to resolve this problem

Thanks in advance

Best regards:
