8571188 Method and device for secure phone banking October 29, 2013
A small form-factor security device is provided that may be inserted in series with a telephone line to encrypt dual tone multi-frequency (DTMF) tones from a telephone to prevent unauthorized disclosure of sensitive information. A receiving device decrypts the encrypted DTMF tones to
8290162 Combinational combiner cryptographic method and apparatus October 16, 2012
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
8259947 Recreating a cryptographic key in a replacement device September 4, 2012
Embodiments describe a method and/or system whereby a secret key in a cryptographic system may be replaced without revealing the secret key. One embodiment comprises creating a first private key and corresponding first public key. A second private key associated with the first private
8046587 Method off-line authentication on a limited-resource device October 25, 2011
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
8019802 Cryptographically secure pseudo-random number generator September 13, 2011
A cryptographically secure pseudo-random number generator is configured to obtain one or more unpredictable sources of entropy that provide a seed. A current internal state of the number generator is modified as a function of the current internal state and the seed to accumulate entr
