Abstract
An integrated circuit accesses first encrypted data stored in an external random access memory and accesses second encrypted data stored in an external read-only memory. The external random access memory and the external read-only memory are external to the integrated circuit. When accessing a first portion of the first encrypted data stored in the external random access memory, a first algorithm is used to decrypt the first portion of the first encrypted data. When accessing a first portion of the second encrypted data stored in the external read-only memory, a second algorithm is used to decrypt the first portion of the second encrypted data. The second algorithm is different than the first algorithm.
