Description

technical field [0001] The invention relates to the technical field of network communication security, in particular to a method and device for realizing a security IP core based on an ECC algorithm. Background technique [0002] At present, the elliptic curve encryption algorithm has been implemented abroad, and many standard documents on elliptic curves such as: IEEE P1363, P1363a, ANSIX9.62X9.63, ISO / IEC14888 have been formulated one after another. However, the application of Elliptic Curve Cryptosystems (ECC) to encryption middleware products is still blank, and the research on ECC-based encryption products is still in its infancy and research stage. [0003] In the national wireless LAN standard GB15629.11 promulgated by China in 2003, the new WAPI security mechanism is based on the elliptic curve encryption algorithm, which also indicates that information security products based on the elliptic curve encryption algorithm will be my country's future wireless LAN communi...

Problems solved by technology

Due to the acceleration of computer processing speed, the computer's ability to decipher information has been continuously improved, resulting in the continuous lengthening of the RSA key. However, due to the weak encryption strength of the RSA encryption algorithm, a longer key is required when using the RSA encryption algorithm to achieve higher security. In addition, the security performance and execution efficiency of the RSA encryption algorithm are low, and the efficiency in mobile terminal devices with low processing power and storage capacity has poor effect
