Hello, I look in vain for the STM32F103 bootloader with secure (encryptet RSA or AES or ..} project For exmamplele Silb have for EFM32 mcu AN0060: Bootloader with AES Encryptio www.silabs.com/.../an0060-bootloader-with-aes-encryption.pdf but ST not and I am also not successful in finding a any project on fithur og other source.
Can somebody help me?
Are these methods materially different between micro controllers of assorted types? Don't paint yourself into a corner.
You need AES encryption/decryption source code, plenty of that on the web, ST has a crypto library, and pretty sure I've seen an app note.

You need an X-MODEM implementation? IAP examples?
