The traditional text SMS is now outdated, particularly with the explosion of popular, secure and easy-to-use messaging apps. Now, we have many options to share about our lives through photos, videos, GIF’S, emojis, and file-sharing to other users. We found lots of different options to stay in touch with friends and family by using these free text messaging apps. More and more enterprises, companies and authorities are looking for secure messengers and chat apps to increase productivity and marketing of their business. Messenger apps that are not just useful, but also entertaining, acquire more users. Secure messaging apps are popular as consumers seek protection from hackers and surveillance.
Messaging is one of the top activities on smartphones. Therefore, it is essential to make sure that these messengers protect both transferred and stored data without limitations and gaps in security. High profile data breaches and leaks make headlines regularly as politicians and companies fail to keep their customers’ sensitive data safe. Secure chat is a truly secure instant messaging (IM) app which delivers OTR text encryption running on XMPP services. To secure data on chat apps, secure chat application offers some of the most conventionally used chat features alongside strict privacy and protected communication concepts. It allows encrypted end-to-end services to exchange of messages, voice, video and, files.
Cyber attackers usually hack apps which are containing sensitive business data, personal information or monetary transaction like payment apps or mobile banking software. Hacker mostly targets banking software, healthcare software and e-commerce applications. To secure important data and communication from cyber threats and hackers, one needs to focus on following points:
1. Secure all communication by end-to-end encryption techniques :
The use of encryption denotes that developers adopt mathematical algorithms to scramble data. It is the best-known way to prevent unwanted parties from making sense of the messages you send. All major messaging apps use some form of encryption to protect your privacy. End-to-end encryption is popular to secure message between client and server or sender and the recipient. Only two people can decode and read messages, even the company that develop the messaging app and stores all messages on the server cannot decrypt the messages.
2. Secure data transfer between client and server
Different transfer layer protocols like Transport Layer Security (TLS) and Secure Sockets Layer (SSL) are cryptographic which are designed to provide secure communication over the Internet. For all chat apps or messaging apps we develop, we make sure to properly set up TLS/SSL. They use X.509 certificates and hence asymmetric cryptography to assure the counterparty with whom they are communicating and to exchange a symmetric key. This session key is then used to encrypt data flowing between the parties. Hence, a secure communication takes place between two parties.
Key features to secure mobile chat app:
• Using SLS messages exchanged within the app can only be decrypted by the sender and recipient.
• Every message has its own private keys.
• All data stored on a device is encrypted by a separate key that’s derived from the password entered by the user.
• To secure data crypto libraries such as AES can be used by the app developers to implement different Android and iOS standards. Remember that data encrypted with this method is only as secure as the password used to derive the key and key management.
Various encryption techniques are useful to prevent cyber threats or hackers for secure communication by chat apps, it depends on your choice. Above methods are your key towards the step -by-step process to achieve secure communication.
