Cryptanalysing variants of Stickel's key agreement scheme

Journal of Mathematical Cryptology, 2011
Stickel's key agreement scheme was successfully cryptanalysed by V. Shpilrain when GL(n, q) is used as a platform. Shpilrain suggested the algebra of all (not necessarily invertible) n × n matrices defined over some finite ring R would make a more secure

Questioning Key Compromise Attack on Ostad-Sharif et al.’s Authentication and Session key Generation Scheme for Healthcare Applications

IEEE Access, 2019
Recently, Ostad-Sharif et al. pointed out the susceptibility of three different authentication schemes themed for telecare medicine/medical information systems to key compromise impersonation attack (KCIA). To further address this issue, they proposed an

A Leakage-Resilient Certificateless Authenticated Key Exchange Protocol Withstanding Side-Channel Attacks

IEEE Access, 2020
Certificateless public-key cryptography has conquered both the certificate management problem in the traditional public-key cryptography and the key escrow problem in the ID-based public-key cryptography. Certificateless authenticated key exchange (CLAKE)

Stressful Events Reported by Childhood Cancer Survivors and Community Controls From the St. Jude Lifetime (SJLIFE) Cohort: A Mixed Method Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Characterizing stressful events reported by childhood cancer survivors experienced throughout the lifespan may help improve trauma‐informed care relevant to the survivor experience. Methods Participants included 2552 survivors (54% female; 34 years of age) and 469 community controls (62% female; 33 years of age) from the St.
