What function does encryption serve in telecommunications?

Encryption in telecommunications serves the critical function of securing data by converting it into a coded format. This process ensures that sensitive information is protected from unauthorized access during transmission. By transforming readable data into an unreadable format, encryption effectively prevents interception by malicious actors. Only those with the correct decryption key can convert the data back to its original form, thereby preserving confidentiality and integrity.

In telecommunications, where data transmission occurs over potentially vulnerable channels, encryption is essential for maintaining secure communications. It helps in protecting personal information, financial transactions, and confidential organizational communications against threats such as eavesdropping and data breaches. By utilizing encryption, organizations can ensure that their communications remain private and secure.
