VULNERABILITIES OF THE SSL/TLS PROTOCOL (original) (raw)

International Journal of Computer Network and Information Security, 2016

Secure Socket Layer (SSL) and Transport Layer Security (TLS) protocols use cryptographic algorithms to secure data and ensure security goals such as Data Confidentiality and Integrity in networking. They are used along with other protocols such as HTTP, SMTP, etc. in applications such as web browsing, electronic mail, and VoIP. The existing versions of the protocols as well as the cryptographic algorithms they use have vulnerabilities and is not resistant towards Man-In-The-Middle (MITM) attacks. Exploiting these vulnerabilities, several attacks have been launched on SSL/TLS such as session hijacking, version degradation, heart bleed, Berserk etc. This paper is a comprehensive analysis of the vulnerabilities in the protocol, attacks launched by exploiting the vulnerabilities and techniques to mitigate the flaws in protocols. A novel taxonomy of the attacks against SSL/TLS has been proposed in this paper. Index Terms-SSL/TLS, vulnerabilities, Man-In-The-Middle (MITM) attack, mitigations, taxonomy of attacks. 10. Change cipher specification: Both server and client agree to work using the decided parameters such as

A STUDY OF THE SSL AND BACKDOOR BASED ATTACKS IN NETWORK ENVIRONMENTS

The security ensures gave by SSL/TLS rely on upon the right confirmation of servers through authentications marked by a trusted power. How-ever, as late episodes have illustrated, confide in these powers is not well set. Progressively, endorsement powers (by pressure or trade off) have been making manufactured endorsements for a scope of foes, permitting apparently secure interchanges to be captured by means of man-in-the-center (MITM) assaults.An assortment of arrangements has been proposed, however their many-sided quality and organization costs have prevented their reception. In this paper, we propose Direct Validation of Certificates (DVCert), a novel convention that, rather than depending on outsiders for testament approval, permits spaces to straightforwardly and safely vouch for their declarations utilizing already settled client validation qualifications.

Man in The Middle Attacks Against SSL/TLS: Mitigation and Defeat

Journal of Cyber Security and Mobility

Network security and related issues have been discussed thoroughly in this paper, especially at transport layer security network protocol, which concern with confidentiality, integrity, availability, authentication, and accountability. To mitigate and defeat Man-in-the-middle-attacks, we have proposed a new model which consists of sender and receiver systems and utilizes a combination of blowfish (BF) and Advanced Encryption Standard (AES) algorithms, symmetric key agreement to distribute public keys, Elliptic Curve Cryptography (ECC) to create secret key, and then Diffe Hellman (DH) for key exchange. Both SHA-256 hashing and Elliptic Curve Digital Signature Algorithm (ECDSA) have been applied for integrity, and authentication, respectively.

A Modular Security Analysis of the TLS Handshake Protocol

Lecture Notes in Computer Science, 2008

We study the security of the widely deployed Secure Session Layer/Transport Layer Security (TLS) key agreement protocol. Our analysis identifies, justifies, and exploits the modularity present in the design of the protocol: the application keys offered to higher level applications are obtained from a master key, which in turn is derived, through interaction, from a pre-master key.

Secure Socket Layer (SSL) in the Network and Web Security

2020

The Meltdown and spectre holes are two security deficiencies which can provide access to personal data for hackers and can potentially affect performances of Linux, Mac systems, and Windows devices plus other operating systems. In order to prevent the capturing data on computer or smartphones by attackers, two vulnerabilities as meltdown and spectre are recently detected on CPU manufacture. Vulnerabilities are part of the hardware design of the processor by changing the processor structures in terms of security enhancement of the CPU manufacture. Meltdown hole is run on a wide range of operating systems including IOS, Linux, MacOS, and Windows which can affect many service providers and cloud services. There are some fixes from manufacturer of OS and BIOS which are trying to fix exploits. Software patches should be used while undergo updating operations should also be applied in order to enhance the security of operating systems. In this paper, the impact of meltdown hole on various...

Analysis of Attacks on TLSv1.3

Analysis of Attacks on TLSv1.3 : ** Developed a Complete TLSv1.3 for secure negotiation between Client and Server using scratch RFC 6066 in C programming in OPENSSL . ** Implemented every extensions proposed in TLSv1.3 using RFC 6066. ** Developed new Sockets formation in TCP mode. ** Implemented binding of each and every Cryptographic protocols like AES-GCM, ECDHE, RSA, Diffie- Hellman and so on, on Network layers for Client.c file to Server.c file for negotiation. ** Implementation and verification of all possible existing newest/best attacks on TLSv1.3.(Reference RFC 7457) & modifying those attacks. [on going] ** Analyzed the ciphers proposed in TLSv1.3 , & analysed the differences with respect to SSL3.0, TLSv1.0, TLSv1.1 and TLSv1.2. - Key Learnings: Unix Operating Systems, Core C , Objective C, Assembly Language(ASM), Computer Architecture, Cryptography & Cryptology, Networking Algorithms, Network & Security, OPENSSL.

Data Transmission Using Secure Socket Layer (SSL) Protocol in Networks-IJAERDV04I0938769.pdf

Concerning illustration associations give additional administrations,furthermore transactions online, security turns into a need. Clients require with a chance to be sure that delicate data for example, such that a credit card number is setting off to a legitimate online business.Associations need will keep client majority of the data private furthermore secure. SSL certificates would be crucial part from the information encryption methodology that make web transactions secure. They need aid advanced passports that give verification should secure the secrecy and integument for website correspondence with browsers.
