Original Abstract Submitted
a real time, on-the-fly data encryption system is operable to encrypt and decrypt data flow between a secure processor and an unsecure external memory systen. multiple memory segments are supported, each with its own separate encryption capability, or no encryption at all. data integrity is ensured by hardware protection from code attempting to access data across memory segment boundaries. protection is also provided against dictionary attacks by monitoring multiple access attempts to the same memory location.
