Adversary Model: Adaptive Chosen Ciphertext Attack with Timing Attack
This work addresses security vulnerabilities in cryptographic systems, particularly for IoT and lightweight devices, though it appears incremental as an extension of prior research.
The paper tackles the problem of enhancing security models by introducing a novel adversary model, CCA2-TA, which combines adaptive chosen ciphertext attacks with timing attacks, and demonstrates its practicality in applications like TFTP protocols.
We have introduced a novel adversary model in Chosen-Ciphertext Attack with Timing Attack (CCA2-TA) and it was a practical model because the model incorporates the timing attack. This paper is an extended paper for 'A Secure TFTP Protocol with Security Proofs'.
