摘要：A method for writing a set of information for processing by a processing unit of an integrated circuit in an external memory outside the integrated circuit, includes: generating, within the integrated circuit, an encryption key; for each item of information intended to be written at an address of the external memory, first encrypting the address within the integrated circuit by a first encryption/decryption circuit using the encryption key to obtain an encrypted address; second encrypting the item of information within the integrated circuit using a second encryption/decryption circuit using the encrypted address to obtain an encrypted item of information; and writing the encrypted item of information at the address of the external memory, wherein the external memory is not able to be written twice at a same address during a write process 申请人：STMicroelectronics (Grenoble 2) SAS
