Image forming apparatus with color adjustment
A image forming apparatus includes a display, a user input device, a printer unit, and a processor. The processor causes a color patch image output screen to be displayed. The color patch image output screen includes user selectable hues. Once the hue selection is received a color patch image based on the hue selection is displayed. The color patch image includes several different colors indexed by a color number value. A color patch number input screen is then displayed and includes a color to be adjusted input field and a target color input field. User inputs for a first color patch number and a second color patch number are received via the displayed screen. The processor then performs a color conversion such that the first color patch number corresponds to the second color patch number when the printer unit prints an image using the image data. |

Synthetic request injection to disambiguate bypassed login events for cloud policy enforcement
The technology disclosed describes a computer-implemented method. The computer-implemented method includes disambiguating a bypassed login event that caused a client to access a cloud application but bypassed a network security system configured to intermediate traffic between the client and the cloud application.

The network security system analyzes the incoming request and detects absence of instance metadata required to determine whether the bypassed login event emanated from a controlled account or an uncontrolled account. The network security system holds the incoming request, generates a synthetic request, and injects the synthetic request into the application session and transmits the synthetic request to the cloud application. The synthetic request is configured to retrieve the instance metadata from the cloud application. |

Techniques are described for providing session management functionalities using an access token (e.g., an Open Authorization (OAuth) access token). Upon successful user authentication, a session (e.g., a single sign-on session) is created for the user along with a user identity token that includes information identifying the session. The user identity token is presentable in an access token request sent to an access token issuer authority (e.g., an OAuth server). Upon receiving the access token request, the user identity token is parsed to identify and validate the session against information stored for the session. The validation can include various session management-related checks. If the validation is successful, the token issuer authority generates the access token. In this manner, the access token that is generated is linked to the session. The access token can then be used by an application to gain access to a protected resource. |

Security information propagation in a network protection system
A network protection system (NPS) is augmented to determine and apply security information for a host on a network. The NPS is configured to monitor the host. In response to an occurrence, e.g., the host requesting a network host address, the NPS dynamically determines the security information and encodes it in a portion of the IP address that is assigned. The particular portion of the IP address that is configured for the security information is identified according to variable-length subnet masking (VLSM) notation and, in particular, by including an additional host identifier subdivision that identifies the portion that carries the relevant security data. The security information (e.g., a rank) is encoded in a bitmask. An IP address that has been extended in this manner is then provided on the network, where it is readily-evaluated by other applications and systems that recover the security information by simply applying the bitmask to the IP address. |

Wireless communications device, infrastructure equipment and methods
Mixture of implicit and explicit signaling of the Synchronization Signal Block (SSB) time index for 5G New Radio. In NR, multiple SSBs (each containing PSS, SSS and PBCH) are sent on different beams, and on multiple time occurrences. The UE when detecting the SSB has therefore to identify the SSB time instance and the beam ID used by the gNB. This detection is allowed by said SSB time index. If sent on the PBCH, this prevents soft combining between PBCH time instances. It is therefore proposed to send the SSB time index via the DMRS interleaved with the PBCH. Problem: overhead would be too high for DMRS solution only. Solution: Part of the bits (the LSBs) of the SSB time index are signaled implicitly via the relative position of PSS, SSS and PBCH within a SSB. The other bits are explicitly sent using DMRS scrambling. |

Unequally powered cryptography using physical unclonable functions
Systems and methods of authentication and encrypted communication between a server and client using independently-generated shared encryption keys are disclosed. Clients with arrays of physical-unclonable-function devices respond to server-issued challenges. The clients derive encryption keys from responses to those challenges generated by measuring PUF devices specified by the challenges. The clients send messages encrypted with the encryption keys to the server. The server independently reproduces the client-generated encryption keys using information about the PUF devices. When the keys match, the clients are authenticated. It may be desirable to inject errors into the challenge responses generated by the clients to improve security. When errors are injected, attackers cannot determine correct challenge responses except by brute force. When a sufficiently large number of errors are introduced, the server has sufficient computational power to successfully authenticate the client, but is computationally infeasible for an attacker to reverse engineer the correct responses. |

Another method is based on differential sensors, one of them having the calibration module disconnected.
