In a world where vulnerabilities extend beyond the realms of bank accounts, homes, and intricate stock exchange networks, even military units face susceptibility to hackers. What’s the common thread? Our ubiquitous phones—the compact devices nestled in every pocket. While they serve as communication hubs for calls and texts, these handheld wonders also enable on-the-go payments, web browsing, and the virtual slinging of birds at digital adversaries. The prevalence of smartphones paints a sizable target on our backs. From individual hackers to entire nation-states, the focus shifts to smartphones, aiming to exploit their access to cameras, microphones, and personal data. This landscape underscores the pressing need for a secure communication solution on all phones.
What Constitutes Secure Communication?
Secure communication entails safeguarding data from unauthorized access through encryption and additional security measures. The process ensures that data is transmitted securely between two or more parties. Encryption, a fundamental component, scrambles data to a form readable only by the intended recipient. Deniable encryption, a specific cryptographic approach, allows encrypted text to be deciphered in multiple ways, contingent on the decryption key used.
What is Encryption?
Encryption is converting information into secret code to conceal its true meaning. This cryptographic method involves encoding and decoding information, where unencrypted data is termed plaintext, and encrypted data is called ciphertext. Encryption relies on algorithms, or ciphers, with a variable called a key, ensuring uniqueness in the output. The key, a crucial part of the algorithm, adds complexity and security, making intercepted messages challenging to decipher. Historically employed by militaries and governments, encryption now safeguards sensitive data in modern computing, protecting stored information and data transmitted over networks. It is a valuable security tool, emphasizing the difficulty of unauthorized entities guessing the encryption algorithm and keys.
What do we need for secure communications on the phone?
For communication to be entirely secure, an end-to-end encrypted solution is necessary. End-to-end encryption is a crucial solution for securing communications, providing a robust safeguard for the privacy of messages. In this encrypted communication model, the message undergoes encryption at the sender’s end and decryption exclusively at the receiver’s end. The message remains encrypted throughout its journey, making it impervious to interception attempts during transmission.
The concept of “end-to-end” underscores that the encryption and decryption processes occur solely at the message’s endpoints—the sender and the receiver. Importantly, no intermediary point in transit engages in the encryption or decryption of the message. This includes servers that relay and store messages, ensuring they cannot decipher or access the message content.
End-to-end encryption employs asymmetric public key encryption, where both parties possess two keys—a public key accessible to all and a private key kept confidential. The public key encodes the message, and only the corresponding private key can decode the encoded message. This definition underscores the necessity of end-to-end encrypted communications for ensuring the utmost security and confidentiality in our digital exchanges.
What do we have now?
Without a federal privacy law, most ad-tech companies and data brokers operate without regulation, shrouded in opacity. This lack of oversight poses a significant challenge for phone owners, as tracking the trajectory of their data or understanding its utilization becomes nearly impossible, let alone preventing its initial sharing. The absence of industry standards further complicates matters, making it challenging for users to discern the possibilities and limitations of any given device. Instead, phone owners are presented with occasionally convoluted menus filled with permissions, often tucked away within an operating system and seldom configured by default with privacy considerations in mind.
It’s crucial to recognize that security is a dynamic concept. An App deemed secure might face vulnerabilities if a zero-day exploit is discovered in its components. Assuming an application’s security relies on incorporating the mentioned features, barring identifying vulnerabilities in its code. Significant privacy and security deficiencies in encrypted messaging apps often stem from the following factors:
- Utilization of unencrypted cloud backups
- Lack of transparency regarding the app’s code, which is not available in open-source
- Deployment of proprietary encryption algorithms
- Optional settings for end-to-end encryption
Also, some messaging applications store unencrypted backups on Cloud-based drives for phones. Some messaging platforms also involve using a proprietary protocol named MTProto, which lacks transparency in safeguarding communications.
