Process monitoring method
InactiveCN102147845AThe process is clear and easy to understandWill not affect the legal processPlatform integrity maintainanceSoftware engineeringApplication programming interface
The invention discloses a process monitoring method, relating to the field of a process monitoring technology. The method comprises the following steps: S1: obtaining the API (application programming interface) address of NtCreateSection and replacing the original NtCreateSection with DetourNtCreateSection; S2: monitoring processes to be created according to the DetourNtCreateSection. The method provided by the invention can be used for intercepting the processes being created in the process of creation rather than after creation, thus enabling the system to be more secure. As the hooked sites are unavoidable paths for process creation, and can not be easily bypassed by Trojans, virus and the like. As a result, the safety can be ensured. In addition, the method is not as complicated as the HOOK ObReferenceObjectByHandle method, and only one API is hooked in the whole process, thus causing the process to be clear and easily understood. The NtCreateSection used in the method provided the invention is placed at a high inner core level and only intercepts processes being created, thus not affecting other valid processes in operation in the system.

A method for improving public Wi-Fi network security based on WPA / WPA2PSK multiple passwords. The invention belongs to the field of information security. Limited by WPA / WPA2PSK, Wi-Fi networks in public places can usually only set a single public password at present. People within the coverage area can steal user information through packet capture and decryption, forged phishing APs, intranet packet capture, and intranet man-in-the-middle attacks, which will bring hidden dangers to user information security. The present invention sets multiple sets of different WPA / WPA2PSK passwords for users to use through a single Wi-Fi network. Users do not know other people's passwords and are isolated from each other, thereby preventing user data from being stolen and improving the confidentiality of Wi-Fi users surfing the Internet in public places And the security of online transactions, while keeping the user's hardware, software, and connection methods unchanged, ensuring compatibility with the original user-end equipment.

The invention relates to the technical field of safe multi-party computing based on fully homomorphic encryption, in particular to a lattice-based distributed relinearization public key generation method. On the basis of the lattice-based public and private key generation method proposed by the BFV, a relinearization public key generation initialization algorithm, a relinearization public key share generation algorithm and a relinearization public key generation algorithm are proposed; firstly, sharing of a user private key is completed based on an analytic polynomial, and calculation of a user about a relinearization public key share is completed through number-theory transformation. And before the individual re-linearization public key share of the user is submitted finally, the user share is protected by utilizing two noises which can be counteracted after being added, so that the condition that a private key can be obtained by analyzing the share when the opponent collects the re-linearization public key share is prevented. According to the method, less noise is utilized, and the safe effect is achieved.
