2. Public-key cryptography - Wikipedia

   en.wikipedia.org/wiki/Public-key_cryptography

   One approach to prevent such attacks involves the use of a public key infrastructure (PKI); a set of roles, policies, and procedures needed to create, manage, distribute, use, store and revoke digital certificates and manage public-key encryption. However, this has potential weaknesses.

3. Public key infrastructure - Wikipedia

   en.wikipedia.org/wiki/Public_key_infrastructure

   A public key infrastructure (PKI) is a system for the creation, storage, and distribution of digital certificates which are used to verify that a particular public key belongs to a certain entity. The PKI creates digital certificates which map public keys to entities, securely stores these certificates in a central repository and revokes them ...

4. PKCS - Wikipedia

   en.wikipedia.org/wiki/PKCS

   PKCS Standards Summary; Version Name Comments PKCS #1: 2.2: RSA Cryptography Standard [1]: See RFC 8017. Defines the mathematical properties and format of RSA public and private keys (ASN.1-encoded in clear-text), and the basic algorithms and encoding/padding schemes for performing RSA encryption, decryption, and producing and verifying signatures.

5. Certificate Transparency - Wikipedia

   en.wikipedia.org/wiki/Certificate_Transparency

   When an internet user interacts with a website, a trusted third party is needed for assurance that the website is legitimate and that the website's encryption key is valid. This third party, called a certificate authority (CA), will issue a certificate for the website that the user's browser can validate. The security of encrypted internet ...

6. X.509 - Wikipedia

   en.wikipedia.org/wiki/X.509

   An early issue with Public Key Infrastructure (PKI) and X.509 certificates was the well known "which directory" problem. The problem is the client does not know where to fetch missing intermediate certificates because the global X.500 directory never materialized. The problem was mitigated by including all intermediate certificates in a request.

7. Public key fingerprint - Wikipedia

   en.wikipedia.org/wiki/Public_key_fingerprint

   When a public key is received over an untrusted channel, such as the Internet, the recipient often wishes to authenticate the public key. Fingerprints can help accomplish this, since their small size allows them to be passed over trusted channels where public keys won't easily fit.

8. Protected Streaming - Wikipedia

   en.wikipedia.org/wiki/Protected_Streaming

   Protected Streaming [1] is a DRM technology by Adobe. The aim of the technology is to protect digital content (video or audio) from unauthorized use. Protected Streaming consists of many different techniques; basically there are two main components: encryption and SWF verification. This technique is used by the Hulu desktop player and the RTÉ ...

9. Secure Real-time Transport Protocol - Wikipedia

   en.wikipedia.org/wiki/Secure_Real-time_Transport...

   The default values of the encryption key and salt key are the same as for AES in counter mode. (AES running in this mode has been chosen to be used in 3G mobile networks.) Besides the AES cipher, SRTP allows the ability to disable encryption outright, using the so-called null encryption cipher, which can be assumed as an alternate supported cipher.
