Subverting Telegram’s End-to-End Encryption
IACR Transactions on Symmetric Cryptology, 2023 Telegram is a popular secure messaging service with third biggest user base as of 2021. In this paper, we analyze the security of Telegram’s end-to-end encryption (E2EE) protocol in presence of mass-surveillance.

Multivariate Profiling of Hulls for Linear Cryptanalysis
IACR Transactions on Symmetric Cryptology, 2018 Extensions of linear cryptanalysis making use of multiple approximations, such as multiple and multidimensional linear cryptanalysis, are an important tool in symmetric-key cryptanalysis, among others being responsible for the best known attacks on ...

A Key Recovery Attack on Edon80 [PDF]
, 2007 Edon80 is a recent stream cipher design that has advanced to the third and last phase of the eSTREAM project. It has remained unbroken and untweaked since it was designed and submitted to eSTREAM. It is now one of the 8 final hardware candidates. In this paper we cryptanalyze the cipher by describing a key recovery attack.

Fault Attacks on the Authenticated Encryption Stream Cipher MORUS
Cryptography, 2018 This paper investigates the application of fault attacks to the authenticated encryption stream cipher algorithm MORUS. We propose fault attacks on MORUS with two different goals: one to breach the confidentiality component, and the other to breach the ...

On the Security of Symmetric Encryption Against Mass Surveillance
IEEE Access, 2020 For mass surveillance, the algorithm substitution attacks (ASAs) are serious security threats to the symmetric encryption schemes. At CRYPTO 2014, Bellare, Paterson, and Rogaway (BPR) formally developed the security notions of decryptability ...

A Direct Key Recovery Attack on SIDH
, 2023 We present an attack on SIDH utilising isogenies between polarized products of two supersingular elliptic curves. In the case of arbitrary starting curve, our attack (discovered independently from [8]) has subexponential complexity, thus significantly reducing the security of SIDH and SIKE. When the endomorphism ring of the starting curve is known, our
