Claim Text:
1. A system comprising: a modem; a display screen; a flash memory; a system memory, including a dynamic random access memory; a plurality of general purpose registers; cryptographic logic to encrypt and decrypt information, the cryptographic logic to support a Data Encryption Standard (DES) algorithm, a triple DES (3DES) algorithm, a Rivest-Shamir-Adleman (RSA) algorithm, and a Diffie Hellman algorithm; an on-chip read only memory to store bootstrap security logic to copy code from the flash memory to a secure memory and to verify authenticity and integrity of the code; and a plurality of execution units coupled to the plurality of general purpose registers, the on-chip read only memory, and the cryptographic logic; wherein the system is to execute the bootstrap security logic when booted up to enable a secure execution environment, and wherein the system is to support a first security privilege level to execute security functions or services, a second security privilege level to execute third-party supplied security code, and access to virtual address spaces inside and outside a secure memory partition by code at the first security privilege level.
