Abstract
This article introduces a key recovery attack on SCB algorithm through the analysis of the stream cipher part.The attack can recover the initial key at the complexity of O(244) with 18 known keystream words.Moreover,the success rate is 100%.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
