Lie algebra representation of the 1+1-dimensional affine Poincaré group via deformation quantization
Balsomo, Alexander J. 
; (Samahang Pisika ng Pilipinas, 2021-08-26)
; (Samahang Pisika ng Pilipinas, 2021-08-26)
In this work, we illustrate an explicit construction of the Lie algebra representations of the 1+1-dimensional affine Poincaré group on the cotangent bundle of cones as its coadjoint orbit. Our main construction tool is ...

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 ...
