Detecting and preventing external modification of passwords
To prevent attackers from logging-in with modified passwords, backup copies of passwords are created and stored. At boot time, the stored passwords are compared to the corresponding backup copies to ensure that they have not been modified. This is done during the boot cycle before the attacker is able to login to the computer. If any passwords have been modified, they are replaced with backup copies, thereby preventing the attacker from logging-in with a modified password. |

Permitting multiple tasks requiring elevated rights
System(s), method(s), and/or technique(s) (“tools”) are described that enable a user to permit multiple tasks requiring elevated rights with as little as one rights elevation. For example, the tools may enable an installation wizard operating within a limited-rights context to perform multiple tasks that require a higher-rights context with a single rights elevation by the user. The tools may do so using an object agent, an instance of which may be created by the installation wizard following a single rights elevation. This instance of the object agent then creates instances of other objects without requiring that the user elevate his or her rights. These other objects' instances may then run the tasks that require the higher-rights context. |

Method and apparatus for a non-revealing do-not-contact list system
A method and apparatus to protect a master do-not-email list from being compromised.

Firewall-tolerant voice-over-internet-protocol (VoIP) emulating SSL or HTTP sessions embedding voice data in cookies
A voice-over-Internet-Protocol (VoIP) client codes audio data as printable ASCII characters, then embeds the ASCII audio data inside a cookie that is sent over the Internet within an HTTP GET message. The GET message is sent to a server acting as a call proxy or external manager that forwards the audio data to a remote client. Return audio data is sent back to the client in the normal data field of an HTTP response message from the server. When the client receives the HTTP response, it sends another GET message without audio data, allowing the server to send another response. This empty GET allows VoIP to pass through strict firewalls that pair each HTTP response with a GET. For secure-sockets layer (SSL), client and server exchange pseudo-keys in hello and finished messages that establish the SSL session. Audio data is streamed in SSL messages instead of encrypted data. |

Firewall control with multiple profiles
A networked computer with a software firewall that may be configured for any of a number of network contexts may be quickly configured with an appropriate set of rules for a current network context. The computer has multiple profiles, each containing rules applicable to a different network context. When a change in network context is detected, a difference between the profile for the current context and the profile with which the firewall was previously configured is determined. These differences are applied to quickly reconfigure the firewall without blocking, even temporarily, communications that are allowed in the previously configured and current profiles. Additionally, when the networked computer is connected to multiple networks simultaneously, an appropriate profile may be selected. |

Enhanced shared secret provisioning protocol
An Enhanced Shared Secret Provisioning Protocol (ESSPP) provides a novel method and system for adding devices to a network in a secure manner. A registration process is launched at two network devices together within a predetermined time interval. These two devices then automatically register with each other. When two devices running ESSPP detect each other, they exchange identities and establish a key that can later be used by the devices to mutually authenticate each other and generate session encryption keys. With ESSPP, two ESSPP devices that are attempting to register with each other will only provision a key when they detect that they are the only two ESSPP devices on the wireless network running ESSPP. If additional devices running ESSPP are detected, the ESSPP protocol is either terminated or suspended. |

Method and apparatus for managing data compression and integrity in a computer storage system
A storage system stores discrete data units and corresponding metadata. The storage system receives data for storage, calculates a first hash value for the data, and identifies a set of compression conditions that correspond to a client ID associated with the data.

The communication form of each terminal which participates in PTT communication is registered in a call control server in advance. When performing PTT communication, a call control server (100a) detects the communication form of each terminal. As a result, speech data is extracted from moving image data transmitted from a transmission terminal and is delivered to a speech PTT terminal which can receive only speech data (S11, S12). On the other hand, moving image data transmitted from a transmission terminal is delivered to a moving image PTT terminal compatible with moving image data without any change (S13). This makes it possible to implement PTT communication in accordance with the communication form of each terminal. |

Mixer with high output power accuracy and low local oscillator leakage
A circuit receives a first signal (for example, a baseband signal) and mixes it with a local oscillator (LO) signal, and outputs a second signal (for example, an RFOUT signal). The circuit includes multiple identical Mixer and Frequency Divider Pair (MFDP) circuits. Each MFDP can be enabled separately. Each MFDP includes a mixer and a frequency divider that provides the mixer with a local version of the LO signal. The MFDP outputs are coupled together so that the output power of the second signal (RFOUT) is the combined output powers of the various MFDPs. By controlling the number of enabled MFDPs, the output power of the second signal is controlled. Because the MFDPs all have identical layouts, accuracy of output power step size is improved. Because LO signal power within the circuit automatically changes in proportion to the number of enabled MFDPs, local oscillator leakage problems are avoided. |

Ultra low-loss CMOS compatible silicon waveguides
A low loss optical waveguiding structure for silicon-on-insulator (SOI)-based arrangements utilizes a tri-material configuration including a rib/strip waveguide formed of a material with a refractive index less than silicon, but greater than the refractive index of the underlying insulating material. In one arrangement, silicon nitride may be used.
