Public Key Infrastructure (PKI) Description: Public Key Infrastructure (PKI) Providing secure communications and authentication over an open network. A Seminar on Moreover, PKI is itself often used as a synonym for a CA implementation. This architecture is referred to as decentralized PKI (DPKI).[27][28]. Basically, an RA is responsible for accepting requests for digital certificates and authenticating the entity making the request. If the two prime numbers are smaller, including, for instance, only two digits, it will be relatively easy for a program to figure out what they are. One of the primary issues PKI addresses is when hackers seek to leverage MITM attacks to intercept and alter or steal information. This means browsers need to carry a large number of different certificate providers, increasing the risk of a key compromise. 5 0 obj SECRET KEY (Blowfish, DES, IDEA, RC2-4-5, The same secret key must be shared by all the, It doesnt scale (proliferation of secrets), Private key is only known by the owner less, Algorithms are 100 1000 times slower than, How are Public keys made available to the other.
