In this thesis, we focus on modular arithmetic hardware algorithms for public-key cryptosystem since these two operations are the computationally most intensive parts in encryption and decryption processes. Afte
We’ve been sharing secrets for centuries, but the Internet runs on a special kind of secret sharing called public-key cryptography. Most secret messages depend on a shared secret—a key or password that everyone agrees on ahead of time. Public-key cryptography shares secret messages without a ...
computation and bandwidth overhead as compared to other schemes using homomorphic public-key encryption. However,Katzenbeisser et al. (2008)protocol has high computational cost for the buyers. This protocol is more efficient due to the use of secure embedding algorithms....
During an SSL handshake, a client and server securely exchange digital signatures and encryption keys by using a public-key algorithm (usually RSA). The client and server establish a secure connection with this identity and key information. After the client and server establish a secure se...

The security of a cryptosystem relies on the private key being kept secret, both when it’s generated and stored. The random numbers used for the algorithms in cryptography must be difficult to guess, that’s why it is not a good option to rely only on software development for the key ge...
Public-Key Encryption The most commonly used implementations of public-key encryption are based on algorithms patented by RSA Data Security. Therefore, this section describes the RSA approach to public-key encryption. Public-key encryption (also called asymmetric encryption) involves a pair of keys...
� It should be noted, however, that the concept of public key cryptography, as discussed here, does not necessarily imply the use of algorithms based on prime numbers. � 但是,应该指出的是,上面所讨论的“公用钥匙加密法”这一概念不一定意味着对基于素数的计算法的使用。 UN-2 It should...

Keywords: encryption with keyword search; certificateless public key cryptography; keyword guessing attacks; trapdoor indistinguishability; provable security1. Introduction Boneh et al. [1] first proposed the notion of public key encryption with keyword search (PEKS). As shown in Figure 1, the workfl...
