Artık veri aktarımını önlemek ve istenilen bilgiyi özetleyebilmek için Kablosuz Algılayıcı Ağlarında (KAA) veri kümeleme vazgeçilmez bir ihtiyaçtır. Genelde saldırılara açık ortamlarda kullanılmaları sebebiyle KAA’lar için bir başka önemli gereklilikte ağ üzerinde taşınan verinin gizliliğinin sağlanmasıdır. Ancak geleneksel veri kümeleme protokollerinde veri kümeleme işlemi sırasında veri gizliliğini sağlamak mümkün değildir. Bu çalışmada literatürdeki veri kümeleme teknikleri incelenip bunların veri gizliliğini sağlayan güvenlik algoritmaları ile olan ilişkileri incelenmiştir. Buna ek olarak homomorfik şifrelemeye dayanan yeni ve orijinal bir güvenli veri kümeleme protokolü sunulmuştur. Geliştirilen protokolde homomorfik şifreleme tekniği kullanılarak şifrelenmiş veriler üzerinden veri kümeleme yapmak mümkündür ve bunun sonucu olarakta kümeleme işlemi sırasında veri gizliliği sağlanabilmektedir.
