How Encryption Enhances Data Protection in Web and Mobile Apps

Data Encryption

  1. Public key or asymmetric encryption: This method uses two different keys. One for encryption aw well as a different one for decryption. We refer to the encryption key as the public key while the decryption key is the private key.
  2. Symmetric encryption: this method uses a single key for encryption and decryption.

Common encryption standards

  1. Data encryption standard (DES) — This standard uses 56 bit long symmetric key algorithm. It was mainly essential in the 70s. However, we consider it very weak due to its short key size.
  2. Triple DES — It is also a symmetric key algorithm. It works by applying the DES cipher thrice to every data bloc. However, it still uses the 56-bit key length.
  3. RSA — This standard is ideal for an app that needs digital signatures. This encryption standard uses an auxiliary value and two secret prime numbers. We use the prime numbers for decryption.
  4. Advanced Encryption Standards (AES) — This symmetric algorithm alongside the block cipher. This is a preferred standard across many encryption tools.
  5. Blowfish & Twofish — Regarding software development, Blowfish is the best bet. It uses a 64-bit block size. On the other hand, Twofish applies the symmetric cipher algorithm. In addition, it is an improved version of the Blowfish. It uses a 128-bit block size algorithm.

States of a Web app and mobile data

  1. Data at rest — This is the data in storage. It is not in transit or operation.
  2. Data in transit is the data moving from one place to another. It could be between public or private networks.
  3. Data in use — This refers to the date undergoing a specified operation.

Why are web apps and mobile data protection essential?

How to use encryption to protect web apps and mobile data

  • Continuously keep review logs of key creation, use, and erasure
  • Tie authorizations to each key to guarantee they have restricted utilizes
  • Influence KMIP (key management interoperability protocol) for secure key circulation with the encoded key vehicle on a TLS divert or disconnected in a split part dispersion
  • Confine admittance to keys to just the individuals who need it, with legitimate client validation, or require a base number of individuals to endorse specific tasks
  • Resign unused keys to lessen any unjustifiable entry
  • Update or pivot encryption keys consistently
  • Utilize a dedicated public key framework
  • Secure access to the critical servers
  • Characterize a crypto time, a proper time frame during which a key is approved for use
  • Pick the right calculation and critical size for every encryption use case
  • Foster strategies and frameworks for key services
