Keeping text messages secure from hackers and eavesdroppers is crucial, yet the government sometimes needs access for criminal investigations. This raises privacy concerns, as tech companies view it as a violation. Text messages are protected by end-to-end encryption, ensuring data remains private in transit. Each smartphone possesses two unique keys: a public key, shared with others for encryption, and a private key, kept confidential on the device for decryption. For secure communication, both parties use their keys to generate a temporary shared key, facilitating a secure chat. For example, when Allyson sends Bob a message, their public keys are exchanged simultaneously to establish this secure connection.
