Detailed herein are embodiments which allow for integrity protected access control to provide defense against deterministic software attacks. Software attacks such as rowhammer attacks which target the TD bit itself are defended against using cryptographic integrity which the data itself is protected by the TD-bit alone. As such, software is reduced to performing only non-deterministic attacks (e.g., random corruption), but all the deterministic attacks are defended against. Additionally, integrity-protected access control bits are protected against simple hardware attacks where the adversary with physical access to the machine can flip TD bits to get ciphertext access in software which can break confidentiality.

Integrity protected access control mechanisms

An optical element is aligned on a flexure by applying multiple laser pulses to the flexure. Additional laser pulses are applied until the optical element is aligned properly.

Method and device for achieving optical alignment using laser pulses

A laser apparatus wherein all optical components are mounted on a unitary, rigid base. Natural frequency modes of the apparatus are above about 2 kHz. Tuning elements in the apparatus may have natural frequencies greater than about 10 kHz.

A transducer suspension system has a transducer head, laminated member, and a load beam. The laminated member is comprised of a support layer, an electrically insulating layer, and an electrically conducting layer. The electrical lines are formed directly into the laminated member. A first end of the support layer has an aperture into which a tongue section protrudes. The transducer head is attached to the tongue section. A platform section is formed between the aperture and the end of the support layer. The electrical lines run to the transducer head along the platform section. The load beam is attached to the laminated member and provides rigid support. The load beam has an aperture located directly above the platform section and provides access to allow clamping of the electrical lines and the platform section during electrical attachment of the lines to the transducer head. Precise electrical attachment is achieved without unwanted bending of the delicate flexure section of the suspension.
