Abstract:
Techniques and apparatus for utilizing bits in a translation look aside buffer (TLB) table to identify and access security parameters to be used in securely accessing data are provided. Any type of bits in the TLB may be used, such as excess bits in a translated address, excess attribute bits, or special purpose bits added specifically for security purposes. In some cases, the security parameters may include an index into a key table for use in retrieving a set of one or more keys to use for encryption and/or decryption.
