Securing Efficiency Through a Standard Testing Laboratory

Securing Security through Education

Traditionally security has been the pervasive factor in organizational growth but its importance has surpassed that of any other issue in retaining a competitive advantage. Security is, therefore, of paramount importance in the retention of organizational innovation. The key in building a secure environment lies in an organizations ability to react to changing threats both from within and exter...

CCA2 Secure IBE: Standard Model Efficiency through Authenticated Symmetric Encryption

We propose two constructions of chosen-ciphertext secure identity-based encryption (IBE) schemes. Our schemes have a security proof in the standard model, yet they offer performance competitive with all known random-oracle based schemes. The efficiency improvement is obtained by combining modifications of the IBE schemes by Waters [41] and Gentry [23] with authenticated symmetric encryption.

Gas migration through cement slurries analysis: A comparative laboratory study

Cementing is an essential part of every drilling operation. Protection of the wellbore from formation fluid invasion is one of the primary tasks of a cement job. Failure in this task results in catastrophic events, such as blow outs. Hence, in order to save the well and avoid risky and operationally difficult remedial cementing, slurry must be optimized to be resistant against gas migration phe...

Some steps towards establishing a tertiary standard dosimetry laboratory at a radiotherapy department

Background: In order to deliver the precise dose to the target in radiotherapy, absorbed dose to water at the reference point should be assessed. When the calibration procedure is performed for a reference dosimeter in the 60Co beam of a Secondary Standard Dosimetry Laboratory (SSDL), the total uncertainty in absorbed dose to water (Dw) is estimated to be approximately 1.5%. This study attempts...
