TLS_ECDH_ECDSA_WITH_ARIA_256_CBC_SHA384

Breakdown of the TLS_ECDH_ECDSA_WITH_ARIA_256_CBC_SHA384 cipher suite

Cyber Security Rating for TLS_ECDH_ECDSA_WITH_ARIA_256_CBC_SHA384 - D

B

Key Exchange Mechanism

Elliptic Curve Diffie Hellman-ECDH

Static Elliptic Curve Diffie Hellman (ECDH) does not use ephemeral (temporary) keys, meaning it violates perfect forward secrecy. ECDHE should be used in preference.

A

Authentication

Elliptic Curve Digital Signature Algorithm-ECDSA

ECDSA (Elliptic Curve Digital Signature Algorithm) is used in cipher suites for authentication and integrity verification. Its efficiency in generating and verifying digital signatures makes it suitable for secure communication protocols like TLS, ensuring data confidentiality and integrity during exchanges over networks.

C

Cipher

AEGIS-ARIA

Cryptographic algorithms with low adoption should be avoided due to several critical reasons. They often lack rigorous scrutiny and testing by the broader cryptographic community, which increases the risk of undetected vulnerabilities. Moreover, their limited deployment means fewer opportunities for real-world validation and feedback, hindering confidence in their security and interoperability with existing systems. High adoption indicates robustness from extensive scrutiny and successful implementation in diverse environments.

A

Hash

Secure Hash Algorithm 384 Bit-SHA384

Improving greatly from SHA1, SHA-256 and above create secure hashes through robust cryptographic algorithms that ensure collision resistance and preimage resistance. They process input data in fixed-size blocks, applying complex mathematical transformations that make it computationally impractical to reverse-engineer the original data from its hash.

D

Cipher Mode

Cipher Block Chaining-CBC

Cipher Block Chaining (CBC) mode is vulnerable to the Lucky13 and POODLE (in TLS v1.2 and below) attacks. The Lucky13 attack exploits timing discrepancies in padding validation, allowing attackers to gradually reveal plaintext. The POODLE attack leverages padding errors to decrypt ciphertext by repeatedly modifying and sending it to the server, observing the error responses. These vulnerabilities arise from CBC's handling of padding and error messages, making it less secure than modern encryption modes like Galois/Counter Mode (GCM), which offer stronger integrity and confidentiality guarantees.

Web infrastructure owners must ensure they only allow secure cipher suites to protect against potential security threats. Cipher suites determine the encryption algorithms and key exchange mechanisms used in HTTPS connections. Insecure cipher suites can leave data vulnerable to interception, decryption, and manipulation by malicious actors. By restricting to secure cipher suites, owners mitigate risks such as data breaches, unauthorized access, and compromise of sensitive information. This proactive measure helps maintain trust with users, ensures compliance with security standards, and safeguards the integrity and confidentiality of data transmitted over the web.
