    摘要： Nanomechanisms are employed in nanomemory elements which, in turn, are employable in nanoscale memory devices. A nanoscale particle is enclosed within a nonocapsule to create a bistable device which is both readable and writable in a variety of ways. A nonamechanism for use in a nanoscale memory element includes a first element in the form of a nanoassembly having a cavity and second element in the form of a nanostructure which is removeably disposed within the cavity. In one embodiment, the nanoassembly is demonstrated as a C480 capsule and the nanostructure is demonstrated as a charged hd 60 fullerene molecule. The nanoscale memory devices combine high switching speed, high packing density and stability with non0volatility of the stored data.

    摘要： Prevention of buffer-overflow attacks on a computer system is presented. In another aspect of the present invention, a Secure Bit is associated with a memory location. A further aspect of the present invention involves modification of semantics to manage the Secure Bit. When the Secure Bit is marked, an interrupt or fault signal is generated.

    摘要： A computer processor protects a protected word in computer readable memory by employing a canary word in the same buffer as the protected word that is protected by a secure bit and/or by employing a canary bit that directly protects the protected word. A bit setting module marks the protected word as tainted by setting the secure bit or canary bit in response to overwrite of the canary word and/or protected word, including overwrite resulting from overflow of the buffer. A validation module validates non-control data stored in the protected word every time the non-control data is used by a computer process by checking the secure bit of the canary word and/or by checking the canary bit of the protected word.

    摘要翻译： 计算机处理器通过在与由安全位保护的受保护字相同的缓冲器中和/或通过使用直接保护受保护字的金丝雀位来使用在与计算机可读存储器中的受保护字保护受保护字。 位设置模块通过设置安全位或加那利位来响应于覆盖加纳利字和/或受保护字的包括由缓冲器溢出导致的覆盖而将受保护字标记为污染。 每当计算机进程使用非控制数据时，通过检查金丝雀字的安全位和/或通过检查受保护字的金丝雀位，验证模块验证存储在受保护字中的非控制数据。
