 Abstract
Although nearly a century old, wireless data transmission has experimented an impressive global development in the last 20-30 years. Nowadays, it is an unanimous accepted fact that wireless networking represents the future of computer and Internet connectivity worldwide. The paper presents a study of the wireless networks, with an emphasis on the cryptographic protocols that ensure the imposed security criteria, proposing, in this respect, an experimental cryptanalysis application for a wireless router, in order to underline the importance of data security protection.

 Rezumat
Lucrarea prezintă o analiză a transmisiei de date folosind rețele wireless, cu evidențierea principalelor categorii de protocoale criptografice care asigură criteriile de securitate impuse, WEP și WPA. In acest sens, este propusă o aplicație experimentală de criptanaliză pentru testarea securității acestui tip de rețea, care folosește echipamente specifice: router wireless de tip TP-LINK TL-WE841N și adaptor wireless de tip TP-LINK TL-WN722NC. Cea mai importantă concluzie, rezultată din determinarea cu success a cheii de criptare, se referă la faptul că protocoalele analizate sunt recomandate numai pentru rețele cu nivel scăzut și nivel mediu de securitate.
