work for Key Stage 3 Planning is a key part of teaching. Without a coherent plan lessons may lack structure and direction. Long and medium term planning are an important part of this and in this rationale I hope to demonstrate that my planning does indeed have all of these qualities. The first element to be considered when rationalising this scheme of work is whether or not it meets the needs of Key Stage 3 pupils. I believe that it does because the attainment focus is all within Key Stage 3.

The study of Public-Key Cryptography Enabled Kerberos Authentication by Sufyan and Mayada (2011) attempt to extend the Kerberos authentication protocol standard to support public key cryptography. This is to eliminate some of the limitations in the standard Kerberos protocol which uses symmetric key cryptography. There are 3 extensions to add support of public-key cryptography at different stages of the Kerberos framework‚ which are PKINIT‚ PKCROSS and PKTAPP. Public-Key Cryptography for Initial

QUESTION BANK 13.1 13.2 Define E-commerce. What are the different types of E-commerce? Explain B2B E-Commerce using an example of a book distributor who stocks a large number of books‚ which he distributes via a large network of book sellers. Assume that the distributor has stocks of books of a large number of publishers and book sellers order books as and when their stock is low. Distributors give 1 month’s time to booksellers for payment. 13.3 Explain B2C E-Commerce of a customer reserving airline

The Dichotomous Asset Pricing Model Evidence from the UK market 1. Introduction Ever since its introduction by Sharpe-Lintner-Black‚ the Capital Asset Pricing Model (CAPM) has been subject to criticism‚ appraisal and continuous efforts for improvement‚ such as the Reward Beta approach (Bornholt‚ 2007)‚ conditional CAPM or the consumption CAPM. The Dichotomous Asset Pricing Model (DAPM)‚ introduced by Professor Liang Zou at the Universiteit van Amsterdam‚ brings a fresh approach to asset pricing

Reasons Why Mayella Ewell is a Dichotomous Character Mayella Ewell is a dichotomous person because she is like any other girl that wants to fit in. The one that wants to be something she’s not. She wants to be beautiful‚ accepted‚ have friends. She is tired of people thinking she’s dirty or feeling unwanted‚ like an outsider. She’s alone in a big room of people and cannot take it anymore. The first reason why she is a dichotomous character is she wanted to be accepted‚ but she can’t because she

INTRODUCTION: Blowfish‚ a symmetric block cipher developed by Bruce Schneier[SCHN93‚ SCHN94)‚ is a Feistel network‚ iterating simple encryption and decryption functions of 16 times each. The block size is 64 bits‚ and the key can be any length up to 448 bits. Although there is a complex initialization phase required before any encryption can take place‚ the actual encryption of data is very efficient on large microprocessors. Blowfish was designed to have the following characteristics: Fast:
