Gerardo, Bobby ; ; (Springer-Verlag Berlin Heidelberg, 2011)
; ; (Springer-Verlag Berlin Heidelberg, 2011)
This paper proposed a model based on hierarchical Clustering and Association Rule, which is intended for decision support system. The proposed system is intended to address the shortcomings of other data mining tools on ...
The performance of Blum-Blum-Shub elliptic curve pseudorandom number generator as WiFi protected access 2 security key generator
Omorog, Challiz D. ; Gerardo, Bobby D. ; Medina, Ruji P. (Association for Computing Machinery, 2018-09-20)
; Gerardo, Bobby D. ; Medina, Ruji P. (Association for Computing Machinery, 2018-09-20)
WiFi Protected Access 2 (WPA2) is considered the most secure network security protocol in wireless routers, despite the discovery of partial key exposure vulnerability. In light of, an experiment was conducted to investigate ...
Analysis of key randomness in improved one-time pad cryptography
; Gerardo, Bobby D. ; Medina, Ruji P. (IEEE Computer Society, 2019-12-09)
; Medina, Ruji P. (IEEE Computer Society, 2019-12-09)
In cryptography, one-time pad (OTP) is claimed to be the perfect secrecy algorithm in several works if all of its features are applied correctly. Its secrecy depends mostly on random keys, which must be truly random and ...
