Abstract

صمم العالمان David Wheeler و Roger Needham خوارزمية التشفير الصغيرة جداً
Tiny Encryption Algorithm (TEA) في مخبر الحاسوب التابع لجامعة كامبردج, وتم نشرها لأول مرة في ورشة عمل تشفير البرمجيات السريع Fast Software Encryption Workshop في العام 1994.

تجمع هذه الخوارزمية خواص الأمان وسهولة التضمين وعدم الحاجة إلى جداول مخصصة والأداء المعقول, وهي صغيرة لدرجة تسمح بتضمينها في أي برنامج وعلى أي حاسوب.

نقدم في هذا البحث دراسة لهذه الخوارزمية موضحين نقاط الضعف فيها والتعديلات التي دخلت عليها منذ ظهورها وحتى الآن، والتي رغم كثرتها لم تنفِ الحاجة المستمرة لتقوية هذه الخوارزمية. نقترح بعد هذه الدراسة أسلوباً جديداً لتقوية هذه الخوارزمية, مبرهنين على نجاعته وسرعته مقارنةً بأساليب التقوية الأخرى.

The Tiny Encryption Algorithm (TEA) was designed by David Wheeler and Roger Needham of the Cambridge Computer Laboratory, and first presented at the Fast Software Encryption workshop in 1994.

This algorithm is a compromise for safety, ease of implementation, lack of specialized tables, and reasonable performance, and is short enough to integrate into almost any program on any computer.

In this paper, we introduce a study of this algorithm highlighting its drawbacks and the modifications to it since it was suggested and until now. These modifications, although many, did not eliminate the continuous need to strengthen this algorithm. After this study, we propose a new method for strengthening TEA proving its efficiency and speed of performance when compared to other strengthening methods.
