Abstract
The authors show that a public key cryptosystem due to Yoo, Hong, Lee, Lim, Yi and Sung is insecure, as it is susceptible to an attack based on the LLL algorithm.
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.
