CVE-2026-84308

phpseclib , a PHP secure communications library, has a non-constant-time X25519 scalar multiplication flaw in versions prior to 3.0.57 and 4.0.1 . The root cause is data-dependent conditional modular reductions in the pure-PHP implementation (Math/PrimeField/Integer.php), which leak per-step timi...

There is an overflow bug in the x6464 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are...

Lightweight Fault Detection Architecture for NTT on FPGA

Post-Quantum Cryptographic PQC algorithms are mathematically secure and resistant to quantum attacks but can still leak sensitive information in hardware implementations due to natural faults or intentional fault injections. The intent fault injection in side-channel attacks reduces the reliabili...

Cost-Effective Optimization and Implementation of the CRT-Paillier Decryption Algorithm for Enhanced Performance

To address the privacy protection problem in cloud computing, privacy enhancement techniques such as the Paillier additive homomorphism algorithm are receiving widespread attention. Paillier algorithm allows addition and scalar multiplication operations in dencrypted state, which can effectively...
