ANÁLISIS COMPARATIVO DE ALGORITMOS CRIPTOGRÁFICOS DE CLAVE PÚBLICA

Abstract

Nowadays the necessity to save and protect the information, is common use dealing referents terms regarding information security , as such, the cryptography-use allows authorized people having access to sensitive information, besides allowing data verification if any unauthorized modification happened, ensuring data authenticity and confidentiality. This work makes a performance analysis of cryptographic primitives of ciphering and digital signature, public key cryptography and identity based public key cryptography. Analysis considers the RSA algorithm for public key cryptography for either ciphering or digital signature and for identity based public key cryptography, using Boneh & Franklin algorithm for ciphering and identity based signature for the digital signature primitive. The analysis takes different computing premises with varying computer resources to determine each execution time for each primitive on each premise. Identity based public key cryptography consider an supersingular elliptic curve due to its ease is of use, where takes bilinear symmetric pairing where .
