Patent number: 9913370Abstract: Tamper-proof electronic packages and fabrication methods are provided which include a glass enclosure enclosing, at least in part, at least one electronic component within a secure volume, and a tamper-respondent detector. The glass enclosure includes stressed glass with a compressively-stressed surface layer, and the tamper-respondent detector monitors, at least in part, the stressed glass to facilitate defining the secure volume. The stressed glass fragments with an attempted intrusion event through the stressed glass, and the tamper-respondent detector detects the fragmenting of the stressed glass. In certain embodiments, the stressed glass may be a machined glass enclosure that has undergone ion-exchange processing, and the compressively-stressed surface layer of the stressed glass may be compressively-stressed to ensure that the stressed glass fragments into glass particles of fragmentation size less than 1000 ?m with the intrusion event.Type: GrantFiled: May 13, 2016Date of Patent: March 6, 2018Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: James A. Busby, Silvio Dragone, Michael J. Fisher, Michael A. Gaynes, David C. Long, Kenneth P. Rodbell, William Santiago-Fernandez, Thomas Weiss

Patent number: 9881880Abstract: Tamper-proof electronic packages and fabrication methods are provided which include a glass substrate. The glass substrate is stressed glass with a compressively-stressed surface layer. Further, one or more electronic components are secured to the glass substrate within a secure volume of the tamper-proof electronic package. In operation, the glass substrate is configured to fragment with an attempted intrusion event into the electronic package, and the fragmenting of the glass substrate also fragments the electronic component(s) secured to the glass substrate, thereby destroying the electronic component(s). In certain implementations, the glass substrate has undergone ion-exchange processing to provide the stressed glass.Type: GrantFiled: May 13, 2016Date of Patent: January 30, 2018Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: James A. Busby, Silvio Dragone, Michael A. Gaynes, Kenneth P. Rodbell, William Santiago-Fernandez

Patent number: 9877383Abstract: Tamper-respondent assemblies and fabrication methods are provided which incorporate enclosure to circuit board protection. The tamper-respondent assemblies include a circuit board, and an electronic enclosure mounted to the circuit board and facilitating enclosing at least one electronic component within a secure volume. A tamper-respondent electronic circuit structure facilitates defining the secure volume, and the tamper-respondent electronic circuit structure includes a tamper-respondent circuit. An adhesive is provided to secure, in part, the electronic enclosure to the circuit board. The adhesive contacts, at least in part, the tamper-respondent circuit so that an attempted separation of the electronic enclosure from the circuit board causes the adhesive to break the tamper-respondent circuit, facilitating detection of the separation by a monitor circuit of the tamper-respondent electronic circuit structure.Type: GrantFiled: February 3, 2017Date of Patent: January 23, 2018Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: William L.

Patent number: 9858776Abstract: Tamper-respondent assemblies and methods of fabrication are provided which include at least one tamper-respondent sensor and a detector. The at least one tamper-respondent sensor includes conductive lines which form, at least in part, at least one tamper-detect network of the tamper-respondent sensor(s). The detector monitors the tamper-respondent sensor(s) by applying an electrical signal to the conductive lines of the at least one tamper-respondent sensor to monitor for a non-linear conductivity change indicative of a tamper event at the tamper-respondent sensor(s). For instance, the detector may monitor a second harmonic of the electrical signal applied to the conductive lines for the non-linear conductivity change indicative of the tamper event, such as an attempted shunt of one or more conductive lines of the tamper-respondent sensor(s).Type: GrantFiled: June 28, 2016Date of Patent: January 2, 2018Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: James A.
