Issue Overview: lib/Crypto/PublicKey/ElGamal.py in PyCrypto through 2.6.1 generates weak ElGamal key parameters, which allows attackers to obtain sensitive information by reading ciphertext data i.e., it does not have semantic security in face of a ciphertext-only attack. The Decisional...

ML-Enhanced AES Anomaly Detection for Real-Time Embedded Security

Advanced Encryption Standard AES is a widely adopted cryptographic algorithm, yet its practical implementations remain susceptible to side-channel and fault injection attacks. In this work, we propose a comprehensive framework that enhances AES-128 encryption security through controlled anomaly...

Accurate BGV Parameters Selection: Accounting for Secret and Public Key Dependencies in Average-Case Analysis

The Brakerski-Gentry-Vaikuntanathan BGV scheme is one of the most significant fully homomorphic encryption FHE schemes. It belongs to a class of FHE schemes whose security is based on the presumed intractability of the Learning with Errors LWE problem and its ring variant RLWE. Such schemes deal...

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: A flaw exists in the Linux kernel related to the bpf and ktls subsystems. A data corruption issue occurs when using bpf msg pop data in ktls. Specifically, the ciphertext length is not...

CVE-2025-24015

Deno is a JavaScript, TypeScript, and WebAssembly runtime. Versions 1.46.0 through 2.1.6 have an issue that affects AES-256-GCM and AES-128-GCM in Deno in which the authentication tag is not being validated. This means tampered ciphertexts or incorrect keys might not be detected, which breaks the...

A Symmetric LWE-Based Multi-Recipient Cryptosystem

This article describes a post-quantum multirecipient symmetric cryptosystem whose security is based on the hardness of the LWE problem. In this scheme a single sender encrypts multiple messages for multiple recipients generating a single ciphertext which is broadcast to the recipients. Each...

GHSA-2X3R-HWV5-P32X Deno's AES GCM authentication tags are not verified

Summary This affects AES-256-GCM and AES-128-GCM in Deno, introduced by commit 0d1beed. Specifically, the authentication tag is not being validated. This means tampered ciphertexts or incorrect keys might not be detected, which breaks the guarantees expected from AES-GCM. Older versions of Deno...

CVE-2021-36751

ENC DataVault 7.2.3 and before, and OEM versions, use an encryption algorithm that is vulnerable to data manipulation without knowledge of the key. This is called ciphertext malleability. There is no data integrity mechanism to detect this manipulation...

CVE-2020-8929

A mis-handling of invalid unicode characters in the Java implementation of Tink versions prior to 1.5 allows an attacker to change the ID part of a ciphertext, which result in the creation of a second ciphertext that can decrypt to the same plaintext. This can be a problem with encrypting...

Fast Plaintext-Ciphertext Matrix Multiplication from Additively Homomorphic Encryption

Plaintext-ciphertext matrix multiplication PC-MM is an indispensable tool in privacy-preserving computations such as secure machine learning and encrypted signal processing. While there are many established algorithms for plaintext-plaintext matrix multiplication, efficiently computing...

Linux Distros Unpatched Vulnerability : CVE-2018-12404

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A cached side channel attack during handshakes using RSA encryption could allow for the decryption of encrypted content. This is a variant of the Adaptive Chose...

GHSA-R38M-44FW-H886 AEADs/ascon-aead: Plaintext exposed in decrypt_in_place_detached even on tag verification failure

Summary In decryptinplacedetached, the decrypted ciphertext which is the correct ciphertext is exposed even if the tag is incorrect. Details This is because in decryptinplace in asconcore.rs, tag verification causes an error to be returned with the plaintext contents still in buffer. The root cau...
