Hi,
I need to encrypt and decrypt information using the AES CBC symmetric key. For this purpose, I'm using the SE050 with functions like: sss_se05x_cipher_init, sss_se05x_cipher_update, sss_se05x_cipher_finish. Everything works fine until at times, when I execute the code in the middle of the process before calling sss_se05x_cipher_finish, I encounter an error (usually at the I2C level where the command doesn't pass, resulting in an error and closing the session). The issue arises the next time I attempt to run the code; the crypto object , defined previously for the operation (kSE05x_CryptoObject_AES_CBC_NOPAD), still exists because I couldn't delete it before closing the session, and I didn't manage to access it. I'm unable to delete it, recreate it, or use it. The only solution that worked for me was changing its ID, allowing it to run smoothly until the next occurrence of the problem. Consequently, I'm essentially "burning" various IDs of the crypto object. I would appreciate hearing if there is a way to solve this issue and delete the crypto object even after the session has closed. I should note that 'delete all' did not succeed in deleting these crypto objects.
Thank you very much.
Hi @Moriya ,
Is it possible to have the APDU command log when you tried to delete/recreate/use this secure object after the issue happened? and it would be helpful if you also send us the log when you encounter this error.
Thanks for your patience!
Have a great day,
Kan

Hi @Moriya ,
Thanks for the information! Just wondering what the SE05x variant is on your hands, was it SE050E or SE050C? especially the applet version inside. Please kindly clarify.
Have a great day,
Kan

Hi @Moriya ,
From the log seems you use a UserID authentication. A crypto object created within an authenticated session can only be used from a session with the same ID as it was created. Was here maybe the authentication changed in between?
Can the object be deleted in the default session (without UserID authentication)?
Please kindly clarify.
Have a great day,
Kan

Hi,
The object was created with a specific UserID, but when I attempt to connect with the same UserID, I'm unable to delete it if it wasn't deleted during its initial creation. Additionally, when I open a session without connecting using the UserID, I still cannot delete it.

Hi @Moriya ,
Have you tried to delete it without opening any user session?

Hi @Moriya ,
How did you create the AES key in the UserID session? What about the policy you attached to this key? Does it allow to delete in both UserID session and the default session ? Please kindly clarify.
Have a great day,
