Abstract
Secure data transmission apparatus comprises a data translator for translating an input string of signals, each signal having incomplete information for identifying an alphanumeric character, into a first encryption key. A data encrypter receives a first encryption key, a choice of encryption algorithm and a message and outputs an encrypted message according to the selected algorithm. The apparatus may be applied whenever the user is confronted with telecommunications apparatus that provides a limited input capability and no means for encrypting a message for transmission to an end user. In this manner, for example, a user may authenticate their name for display on caller identification plus name apparatus and the called party can be assured, before answering their line, that the call is from the party having the displayed name.
