Methods, apparatus and articles of manufacture for detecting illegitimate code generators are provided herein. A method includes generating a set of multiple verification algorithms; generating multiple versions of an authentication code associated with a protected resource, wherein each of the multiple versions of the authentication code satisfies all of the multiple verification algorithms; providing a first version of the authentication code from the multiple versions of the authentication code to a recipient, wherein the first version of the authentication code includes a first verification algorithm from the set of multiple verification algorithms; and providing a second version of the authentication code from the multiple versions of the authentication code to the recipient, wherein the second version of the authentication code includes (i) the first verification algorithm from the set of multiple verification algorithms and (ii) a second verification algorithm from the set of multiple verification algorithms.

Detecting illegitimate code generators

Methods, apparatus and articles of manufacture for key management in full disk and file-level encryption are provided herein. A method includes fetching a distinct cryptographic key from a secure module in connection with a request to perform one of a decryption operation and an encryption operation on at least one of an individual file and an individual sector within a storage device on a computing device; using the distinct cryptographic key to perform the one of a decryption operation and an encryption operation on the at least one of an individual file and an individual sector within the storage device on the computing device; and discarding the distinct cryptographic key subsequent to said performing the one of a decryption operation and an encryption operation on at least one of an individual file and an individual sector within the storage device on the computing device.

Key management in full disk and file-level encryption

Techniques for secure voice authentication. In one example, a method includes the following steps. A first computing device initiates establishment of a secure channel between the first computing device and a second computing device. The first computing device includes a trusted device and the second computing device at least partially hosts a service that a user of the trusted device seeks to access. A prompt is received at the first computing device from the second computing device over the secure channel. The prompt requests a user voice response for use in making an authentication decision for the user based on the user voice response.
