Does Your Banking App Need Two-Way Encryption?

Is your banking app vulnerable?

Similar to COVID, hacking has become increasingly common these days. As many businesses and individuals move online, the consequences of information stolen due to hacking can be critical.

Banking apps are particularly vulnerable to attacks such as these. In 2020, Positive Technologies conducted a study involving 14 mobile banking applications and tested them for vulnerabilities and threats. From the client’s side, attackers can access a user’s data in 13 out of the 14 applications tested. Meanwhile, on the server’s side, the study found on average 23 server-side vulnerabilities on each app.

Recent tests such as Positive Technologies provide a compelling case as to why banking apps need firm and rigid security measures in place. One such example of bolstering defense is including two-way encryption on mobile banking apps.

What Is Data Encryption?

Data encryption transforms data into another form so that only people with a secret key or password can interpret the information. By taking the data and scrambling the original message, this technology prevents third parties from understanding the private data even if they intercept it during the transfer process.

Additionally, there are three drive key security initiatives that maintain confidentiality during the data encryption process. They include:

  • Authentication – This security initiative confirms the message’s origins.
  • Integrity – The system provides evidence that the message has not been altered since it was initially sent.
  • Non-repudiation – Non-repudiation makes it impossible for the message sender to deny accountability for having sent the message.

How do Hackers get Past Data Encryption?

There are two key ways that hackers can break security measures protecting data encryption:

  • Brute Force
    • The encryption is as strong as the length of the key size. Hackers may try random keys until the right one is found, but the process is long and arduous.
  • Side-channel attacks and cryptanalysis
    • By using side-channel attacks, hackers use the errors in system design or execution to sneak into the cipher.
    • Cryptanalysis exploits a weakness of the cipher.

 

However, there are various banking apps that will notify you if your information was compromised. For example, if Bank of America notices a suspicious transaction, they will send you a notification instantly and give you 60 days to verify or decline the claim.

 

What is Two-Way Encryption?

Two-way encryption involves an encrypt and decrypt function. Encrypting is the process of taking plain text and scrambling the message into an unreadable format. After someone inserts their password, the contents are scrambled and the information is sent to another entity.

This entity, the recipient, receives the ciphertext and transforms the information into the original message – this is referred to as decryption. Both the sender and recipient must use a secret encryption key to unlock the message.

How can Two-Way Encryption Make my Banking App Safer?

Encrypted data can only be read by someone with a code or password that unlocks the information. Typically, hackers cannot access this information without using brute force or other methods.

However, two types of security methods that further enhance php two-way encryption. They are as follows:

  • Symmetric encryption
    • This process uses a single password to encrypt and decrypt the password.
  • Asymmetric encryption
    • Two secret codes are needed for encryption and decryption. A public key encrypts the data, while a private key decrypts the user’s information.

Furthermore, there are various types of encryptions that have been used or are currently in place at various institutions. These include:

  • Data Encryption Standard (DES)
    • The DES was established in 1977 by the U.S. Government but is now considered obsolete because of its low-level standard.
  • Triple DES
    • The process runs encryption three times. For instance, it would encrypt, decrypt, and then encrypt data. By repeating the encryption process at the end, this method strengthens the original DES standard.
  • Advanced Encryption Standard (AES)
    • AES encryption is the U.S. standard security system since 2002, effectively replacing the DES.

Other Features to Make your Banking App Safer

Now that you know the basic overview of two-way encryption, you may consider using it along with other security measures. In doing so, you may develop trust between you and the consumer, and further protect their valuable information.

Distributed Denial of Service (DDoS) Prevention

DDoS is known as a brute-force tactic in which hackers attempt to overload a website. By doing so, they make the website unable to respond to actual users’ requests. You can prevent these attacks by having a dedicated server, as it is more capable of security defense than a public server. If you want to learn more about anonymous DDoS attacks and other helpful security measures for your banking apps, then please refer to our article that goes into greater depth about protecting your banking app.

Biometrics

The biometric system captures unique and useful information about a person for security reasons. This information may include:

  • Face recognition
  • Voice recognition
  • Behavior
  • Specific characteristics

When Onsharp worked with Gate City Bank, we created a Touch-ID on the login page of the mobile app. Not only does it make it easier for users to use their account, but by requiring their fingerprint, we made sure that Gate City Bank’s security is of a high standard.

Personalized App Alerts

In giving users greater control to customize their alerts, they can be informed of important information in real-time. They can choose to have all kinds of alerts, such as:

  • Balance or Account alerts
  • Security alerts
  • Tips and guidance
  • Event alerts

Conclusion: Does Your Banking App Need Two-Way Encryption?

The short answer is, yes, your banking apps can greatly benefit from two-way encryption, especially with an uptick in hacking in recent years.

There are also plenty of ways to enforce security on your banking app beyond two-way encryption.
