Future-proof Transactions with Digital Signatures

Vijith Menon

In a rapidly advancing digital world, data is prioritized by organizations. It is sacrosanct and safeguarded for providing secure business transactions. As organizations shift from paper-based processes to digital ways, digital transformation has provided convenience and accuracy. But it has brought to the fore its own set of challenges.

Online Threats to Organizational Security 

India is one of the fastest-scaling technology hubs, with an increased risk of cyber threats. Data and networks need to be protected from unauthorized theft or access. Electronic governance will be a prime issue in protecting companies' proprietary data. The country's large number of users and enterprises make it a prime target.

Cybersecurity approaches need to be prioritized and addressed by companies to protect data integrity. It has gained importance as the government has created awareness initiatives to implement strong measures to protect data, such as two-factor authentication, data encryption, and data authentication. As digital trends evolve, so do the risks. It has become imperative for organizations to stay ahead of the curve to protect data during transit.

Changing from paper processes to digital ones always raises the question of document security, especially in the case of signatures. Whether you’re requesting signatures or signing them, the fact that they are secure and legally valid provides peace of mind.

What is a secure digital signature? 

Digital signatures offer a secure online document signing method based on public-key infrastructure (PKI). It involves using private and public keys to validate signatures. The process does not aim for confidentiality. The sender creates a signature with the private key, while the recipient verifies it with the public key, ensuring it's the same user. Trust between parties prevents forgery. The digital document becomes valid when information is verified using private and public keys.

Digital signatures are legally valid as long as companies or individuals employ solutions that adhere to relevant legislation. In challenging times, organizations need to provide a secure signing solution. Digital signatures that have the backing of trusted service providers will have the utmost trust.

Role of Asymmetric Encryption

Asymmetric encryption, or public-key cryptography, uses a pair of keys for secure data encryption and decryption. It involves a public key, shared openly, and a private key, kept secret. The sender encrypts data with the recipient's public key, and the recipient decrypts it with their private key. This method enables secure communication without sharing a common secret key. Asymmetric encryption finds wide applications in secure online communication, digital signatures, and secure data transfer.

Advantages of Public-key Cryptography

  • Enhanced Security - Asymmetric encryption offers higher security than symmetric encryption, using different keys for encryption and decryption. The private key, known only to the receiver, makes data interception and decryption more challenging for attackers.

  • Authentication - Asymmetric encryption enables authentication, where the receiver verifies the sender's identity. The sender is able to encrypt the message with their private key, and only the corresponding public key can decrypt it. Successful decryption proves the sender's authenticity.

  • Non-repudiation - With asymmetric encryption, non-repudiation is ensured. The sender cannot deny sending or altering the message because it's encrypted with their private key. The receiver can be certain of the message's origin and integrity.

  • Key Distribution - Asymmetric encryption foregoes the need for a secure key distribution system required in symmetric encryption. Public keys can be openly shared, while the receiver keeps private keys secret.

  • Versatility - Asymmetric encryption finds use in various applications like secure email communication, online banking, e-commerce, and secure SSL/TSL connections for internet traffic.

Are Digital Signatures Legal? 

Digital signatures are legally recognized under the Information Technology Act, 2000 (ITA). The digital certificates are certified by a leading certifying authority, eMudhra, and compliant with the ITA.

The law protects documents or contracts that have been signed electronically. This is provided that they follow the rules of a contract. Moreover, an electronic signature or e-signature is considered reliable if the signature creation data is recorded and any modifications to the signature can be followed with the help of a real-time mail trail.

The future of data protection requires an approach to safeguarding the data from compromise, corruption, or loss. Proper protocols must be established to allow access to authorized personnel to sensitive documents. Companies regularly store sensitive information on clients, business partners, and others. Data protection is a legal necessity to protect business relationships' trust and maintain your reputation.

Since the pandemic, customers have been willing to sever ties with companies that break their trust. Since a method is required to trust the validity of processes and the authenticity of users, digital signatures are a secure method. The measures within digital signature solutions ensure documents are untampered and the identity of signers is proven.

Digital signatures employ public-key infrastructure to protect users. A real-time mail trail assures the authenticity of all signers and the validity of associated documents. One-time password and two-factor authentication are security measures to provide access to the right user.
