Patent number: 8290162Abstract: Another feature provides an efficient encryption method that safeguards the security of encrypted symbols. Each plaintext symbol is encrypted by using a separate pseudorandomly selected translation table. Rather than pre-storing every possible permutation of symbols as translation tables, the translation tables may be efficiently generated on-the-fly based on a pseudorandom number and a symbol shuffling algorithm. A receiving device may similarly generate reverse translation tables on-the-fly to decrypt received encrypted symbols.Type: GrantFiled: December 15, 2006Date of Patent: October 16, 2012Assignee: QUALCOMM IncorporatedInventors: Alexander Gantman, Gregory G.

Publication number: 20120069992Abstract: A system is provided for inside-to-outside or outside-to-inside cryptographic coding that facilitates product authentication along a distribution channel. An association of authenticated, secured codes is generated between inner items (e.g., pharmaceutical doses such as pills, capsules, tablets) and outer items (e.g., packaging containing inner items). For instance, an inner code associated with a first item is used to generate (at least partially) an outer code associated with a second item that contains one or more first items. This process may be repeated multiple times with codes for outer items being a function of codes for inner items. The sequence of items may be authenticated by the dependent relationship between their codes.Type: ApplicationFiled: September 22, 2010Publication date: March 22, 2012Applicant: QUALCOMM IncorporatedInventors: John Jozwiak, Gregory G.

Patent number: 8046587Abstract: One feature provides a method for granting authenticated access to off-line, limited-resource mobile devices. A public-private key pair is generated by a service provider and the public key is used to digitally sign a username and (possibly) access privileges to obtain a password for technician. The public key is securely distributed to mobile devices. When off-line, a mobile device may authenticate access to restricted functions of the mobile device by a technician. The technician provides its username, access privileges and password to the mobile device. The mobile device then uses the public key, username and access privileges to verify the password. To invalidate an old username and password, the service provider replaces the public-private key pair with a new public-private key pair.Type: GrantFiled: December 11, 2006Date of Patent: October 25, 2011Assignee: QUALCOMM IncorporatedInventors: Alexander Gantman, Gregory G.

Publication number: 20110238972Abstract: A mutual authentication method is provided for securely agreeing application-security keys with mobile terminals supporting legacy Subscriber Identity Modules (e.g., GSM SIM and CDMA2000 R-UIM, which do not support 3G AKA mechanisms). A challenge-response key exchange is implemented between a bootstrapping server function (BSF) and mobile terminal (MT). The BSF generates an authentication challenge and sends it to the MT under a server-authenticated public key mechanism. The MT receives the challenge and determines whether it originates from the BSF based on a bootstrapping server certificate. The MT formulates a response to the authentication challenge based on keys derived from the authentication challenge and a pre-shared secret key. The BSF receives the authentication response and verifies whether it originates from the MT.Type: ApplicationFiled: May 23, 2011Publication date: September 29, 2011Applicant: QUALCOMM IncorporatedInventors: James F.

Patent number: 7966497Abstract: A hand-held token can be operated to generate an acoustic or other wireless signal representing a digital signature produced from the private key of a public key/private key pair, with the public key being confidential in that it is known only to authorized entities, such as bank computers. The signal from the token can be received by, e.g., a receiver at a bank ATM that also requires a PIN for account access. The user enters the PIN into the ATM, and the ATM encrypts the signal from the token with the PIN and sends it on to the bank computer over a link that need not be secure, since even if the PIN is guessed there is no way to verify that it is the correct PIN without also knowing the confidential public key held by the bank computer.Type: GrantFiled: May 6, 2002Date of Patent: June 21, 2011Assignee: Qualcomm IncorporatedInventors: Alexander Gantman, Gregory G.

Publication number: 20100318162Abstract: Methods and systems enable thermal treating a portion of a subject using microwave or other electromagnetic radiation without harming other portions of the subject. In an embodiment, a plurality of electromagnetic radiation transmitters are positioned within a thermal treatment system and coupled to a control processor. The electromagnetic radiation may be transmitted as a pseudorandom waveform and maybe microwave radiation. The control processor coordinates the transmitters so that emitted electromagnetic radiation constructively interferes within a treatment volume while radiation passing through the rest of the subject randomly interferes or appears as noise. As a result, in a volume in which the electromagnetic radiation waveforms arrive in phase the power of all the transmitters add constructively resulting in a significant temperature rise, while the rest of the subject is exposed to a much lower average power level and thus a lower temperature rise.Type: ApplicationFiled: June 10, 2009Publication date: December 16, 2010Inventor: Gregory G.
