Algebraic immunity is a new cryptographic criterion. In order to resist algebraic attacks, Boolean functions used in cryptosystem should have high algebraic immunity. This paper presents a new recursive construction of Boolean function with maximum algebraic immunity. The constructed Boolean functions are pointed out to be balanced.
The current status of Chinese question answering system (QA) was introduced in the paper firstly. QA is the study on the methodology that returns exact answers to natural language questions. This paper attempts to increase the speed of the system responding to the users and accuracy of QA systems. To achieve this objective, the processing includes: Firstly, it introduces the conceptual theory and...
Fault diagnosis is a complex problem that concerns effective decision-making. Carrying out timely system diagnosis whenever a failure symptom is detected would help to reduce system maintenance time and improve the overall productivity. However, with the increased complexity of equipments, the task of fault diagnosis has become increasingly difficult and its complexity almost unmanageable using traditional...
