A method of protecting a telecommunication terminal having a chip-card-type personal component which is required for telecommunication network access. The terminal includes a processing unit, at least one operating memory element containing the information necessary to the operation of the terminal, i.e. a terminal operating program, and the data necessary to the program. The method involves: a) encrypting the contents of the operating memory element of the telecommunication terminal using a pre-determined key K which is necessary for decryption; and b) allowing the terminal to commence decryption once the terminal has been started with a start-up program that is saved in a secure memory element and once the key for decryption has been calculated by same.

Method of protecting a mobile-telephone-type telecommunication terminal

A device includes a carrier and an integrated circuit chip having a first side supported by the carrier and a second side having contacts. The carrier has multiple carrier contacts supported by the carrier and separated from the integrated circuit chip. Multiple leads are coupled between the contacts on the integrated circuit chip and the multiple carrier contacts. A resin encapsulates the integrated circuit chip leaving the multiple carrier contacts at least partially uncovered for attaching to a card or board.
