Abstract
In a telecommunications system, data having a higher sensitivity and data having a lower sensitivity are identified within a data set. The data having a higher sensitivity is encrypted to produce encrypted sensitive data. Thereafter, the data having a lower sensitivity and the encrypted sensitive data are encrypted to produce an encrypted data set. The encrypted data set is then transferred from a sending unit to a receiving unit. Decryption information may be appended to the encrypted sensitive data before the data having a lower sensitivity and the encrypted sensitive data are encrypted to produce an encrypted data set. The decryption information may include an algorithm identifier, a key identifier, and receiver response instructions. At the receiving unit, the data set is decrypted to recover the data having lower sensitivity. A second decryption of the encrypted sensitive information recovers the data having a higher sensitivity. Appended decryption information may be used to locate and decrypt the encrypted sensitive information.
