Abstract
In this paper, a new stream encryption algorithm called NSA (New Stream Algorithm) is proposed. This algorithm uses a 128-bit secret key and 128-bit seed vectors and produces a 64-bit output value in each round. The suitability of the algorithm for architectural and software implementations, security against resynchronization attack, linked key attack and linear correlation of output sequence attacks are evaluated. The robustness of the NSA algorithm against relevant key-based attacks and resynchronization attacks, as well as traditional methods such as differential and linear cryptanalysis, is analyzed in detail. The analysis results confirm that the NSA algorithm is a secure stream encryption algorithm. At the same time, the ability of the algorithm to resist various threats, including resistance to traditional and modern threats, is discussed. Analysis confirms that this algorithm is a secure stream encryption algorithm.
