Abstract:

Techniques for establishing and enforcing row level database security are presented. Qualifiers are used to uniquely identify particular rows of a database table. The qualifiers are selectively combined to generate a hash value. The hash value is associated with a user. The user is permitted to accesses selective rows of the database table in response to the rows represented in the hash value, which is associated with the user.

Abstract:

A tamper mass including particulate material held together by a binder in a elf-contained supporting shape surrounding a concavity in a forward face containing an explosive, whereby upon detonation of the explosive, the tamper material provides initial and temporary confinement of detonation products to directing forces forward. After shock loading, the tamper material disintegrates into very fine particles, which individually contain very little energy in dispersion.

Abstract:

A method for testing cryptographic algorithms includes: receiving one or more request files, wherein each request files is associated with a cryptographic algorithm and includes a plurality of tests; formatting the plurality of tests in each of the request files based on algorithm formatting rules; transmitting the request files; receiving a plurality of test results for each of the transmitted request files, wherein each test result corresponds to a test included in the respective request file and is generated by execution of the corresponding test using the cryptographic algorithm associated with the respective request file; generating a response file for each of the request files, wherein the response files includes a plurality of test results that correspond to each test included in the corresponding request file; formatting the plurality of tests results in each of the generated response files based on result formatting rules; and transmitting the response files.
