TLDR
In this paper, a method for randomly scrambling the physical address of a block of data, within a memory subject to data site deterioration, by utilizing an auxiliary correspondence memory to pair each logical input/output address with a physical memory address at a random time.
Abstract
A method for randomly scrambling the physical address of a block of data, within a memory subject to data site deterioration, by utilizing an auxiliary correspondence memory to pair each logical input/output address with a physical memory address at a random time. Apparatus for implementing the novel method is also disclosed.

Encryption and authentication method and circuit for synchronous smart card

TL;DR: In this article, the authors present a scheme to authenticate smart cards without microprocessors by using encryption with a secret card data table on which recursive cycles are executed, where each cycle, a word is read out of the table, said word being at an address that is at least partially defined by the word read out in the previous cycle.

Mass-storage applications of local probe arrays

TL;DR: In this paper, a storage device consisting of a local probe array (72) and a storage medium (70) with an array of storage fields (71) is presented, where each local probe can be scanned over the corresponding storage field.
Patent

Tamper resistant software - mass data encoding

TL;DR: In this paper, the authors present a method and system of protecting mass data by mapping virtual addresses onto randomly or pseudo-randomly selected actual addresses, so that an attacker cannot locate the data he is seeking, or identify patterns which might allow him to obtain information about his target (such as how the software operates, encryption keys, biometric data or passwords stored therein, or algorithms it uses).

Shift-shuffle memory system with rapid sequential access

TL;DR: A shift register memory has interconnections among its internal stages permitting stored data to be rearranged in two different ways as discussed by the authors, similar to the shuffling of cards in a deck when shuffled.

Data processor reorder random access memory

TL;DR: Random access memory addressing system for mapping data into a memory according to one schema and retrieving the stored data according to another schema using minimum storage locations is proposed in this paper, which is a RMA addressing system.
