Cryptography on Android Messaging Application using End to End Encryption

Alice and Bob, who the FOCI are they?: Analysis of end-to-end encryption in the LINE messaging application

End-to-end encryption (E2EE) is becoming a standard feature in many popular chat apps, but independent security assessments of these implementations are limited. In this paper we provide the first independent analysis of E2EE features in LINE, a messaging application popular in Asian markets, and identify a replay attack and an attack on a lack of forward secrecy. Based on our analysis and comm...

End-to-End Cryptography: Spreading Democracy

Due to concerns related to the security and privacy of conventional and electronic voting systems as well as the shortcomings of some verification methods, such as Voter Verified Paper Audit Trails (VVPATs), an alternative approach known as End-to-End (E2E) voter verifiable system was proposed. E2E systems rely on cryptography to provide voters and the public with both secrecy and accuracy, two...

Social Authentication for End-to-End Encryption

STEED — Usable End-to-End Encryption

End-to-end e-mail encryption is still ignored by almost all users. The mails are left in the clear in the mailboxes of the web mail providers, where they are frequently collected by attackers and lead to an escalation of the attack due to the sensitivity of the mail content. We suggest a new and simplified infrastructure to protect mail that is compatible with OpenPGP and S/MIME and relies on a...
