Abstract: In one embodiment, a computer-implemented method includes extracting first key derivation data from a first row of data to be stored in a database, where the database includes two or more rows of data. A first encryption subkey is generated, by a computer processor, by combining the first key derivation data with a static key. One or more sensitive fields in each row of the two or more rows of the database are encrypted using a unique corresponding encryption subkey for the row, and the first encryption subkey is unique to the first row among the two or more rows of the database. The one or more sensitive fields in the first row of data are encrypted with format-preserving encryption using the first encryption subkey. The first row of data, including the encrypted one or more sensitive fields, are stored in the database.

Abstract: A method for creating entropy in a virtualized computing environment includes waking one or more samplers, each sampler having a sampling frequency; sampling a sample source with each of the one or more samplers; placing each of the samplers in an inactive state when not sampling; determining a difference between an expected value and a sampled value at each sampler; and providing a function of the difference from each of the one or more samplers to an aggregator.

Abstract: A method, system, and computer program product to generate results for a query to an encrypted database stored on a host are described. The method includes generating indexes from the encrypted database, each index identifying records of the encrypted database associated with a range of data for at least one field stored in the records of the encrypted database, and generating index metadata associated with each index, the index metadata indicating the range of data identified by the associated index. The method also includes generating a sub-query from the query for each field associated with the query and determining a subspace of search within the encrypted database based on sub-query results obtained through the index metadata. The method further includes searching the subspace of the encrypted database to generate the results of the query.

Abstract: A processor-implemented method for a secure processing environment for protecting sensitive information is provided. The processor-implemented method may include receiving encrypted data and routing the encrypted data to the secure processing environment. Then the encrypted data may be decrypted and fields containing sensitive information may be found. The method may also include obfuscating the sensitive information and returning, by the secure processing environment, the decrypted data and obfuscated data.

Abstract: An automated secure record management system and method that receives a plurality of digitally signed records subsequent to a resetting of a running counter. In response to each received digitally signed record, the automated secure record management system and method increments the running counter. Further, upon receiving an accumulation record, automated secure record management system and method compares a value of the running counter and a signature record number of the accumulation record, such that a notification is generated whenever the comparison detects that the value of the running counter is not equal to the signature record number.

Abstract: Access to encrypted data on a removable computer media such as a computer tape is controlled via a uniquely-structured header on the medium having a symmetrical key wrapped by asymmetrical encryption plus a public key associated with the asymmetrical encryption. The data on the medium is encrypted using the symmetrical key. Prior to automated reading of the data by a reader, a challenge is issued to a host system including the public key and preferably a nonce value. The host responds by signing the nonce using a private key associated with the public key in order to prove it has rights to decrypt the data. The symmetrical key is unwrapped using the private key, and finally the unwrapped symmetrical key is used to decrypt the data on the medium, thereby allowing automated reading of the tape data without the need or risk of two administrators sharing a symmetrical key value.

Abstract: A method, apparatus and program storage device for program verification in an information handling system in which an application program runs on an operating system having a signature verification function for verifying a digital signature of the application program. Upon loading of the application program, the signature verification function of the operating system verifies the digital signature of the application program and, if the digital signature is verified, initiates execution of the application program. Upon initiation of execution of the application program, a verification testing function associated with the application program tests the signature verification function of the operating system by presenting to it a sequence of test digital signatures in a specified pattern of true and false signatures. If its test of the signature verification function of the operating system is successful, the application program initiates normal execution.
