摘要： Certain aspects of the invention for producing a secure key may comprise a secure key generator that receives a first, second and third input keys and utilizes these keys to generate a first output key. The first, second and third input keys may be a customer key, customer key selection and key variation, respectively. The first output key may be generated so that it is unique, differs from the first input key and is not a weak or semi-weak key. The first, second and third input keys may be mapped to generate mapped output key data and an intermediate key generated based on the first input key. The intermediate key and the output key data may be scrambled to create a scrambled output. At least a portion of the output key data may be masked and XORed with the scrambled output to generate the first output key.

摘要： Method and system for secure key authentication and key ladder are provided herein. Aspects of the method for secure key authentication may include generating a digital signature of a secure key in order to obtain a digitally signed secure key and transmitting the digitally signed secure key from a first location to a second location. The digital signature may be generated by utilizing an asymmetric encryption algorithm and/or a symmetric encryption algorithm. The digitally signed secure key may be encrypted prior to transmission. The secure key may be a master key, a work key and/or a scrambling key. The digitally signed secure key may be received at the second location and the digitally signed secure key may be decrypted to obtain a decrypted digitally signed secure key.

摘要： Systems and methods that support storage device content authentication are provided. A system that verifies storage device content received from a storage device may comprise, for example, a security processor coupled to the storage device. The security processor may be adapted to receive a partitioned storage device region from the storage device. The partitioned storage device region may comprise, for example, regional content and first hashed regional content. The security processor may generate, for example, second hashed regional content by performing a hashing function on the regional content received by the security processor. The security processor may compare, for example, the first hashed regional content to the second hashed regional content. The security processor may verify the regional content received by the security processor if the first hashed regional content is the same as the second hashed regional content.
