公開鍵暗号 （こうかいかぎあんごう、 英語: Public-key cryptography ）とは、 暗号化 と 復号 とに異なる 鍵 （手順）を用い、暗号化用の鍵は公開できるようにした 暗号方式 である（復号用の鍵は秘匿）。. 対照的な暗号方式として、 暗号化 と 復号 に同一の鍵 ...
RSA-Kryptosystem. RSA ( Rivest–Shamir–Adleman) ist ein asymmetrisches kryptographisches Verfahren, das sowohl zum Verschlüsseln als auch zum digitalen Signieren verwendet werden kann. [1] Es verwendet ein Schlüsselpaar, bestehend aus einem privaten Schlüssel, der zum Entschlüsseln oder Signieren von Daten verwendet wird, und einem ...
وظيفة الـ (PKI) والغرض منه. ترتيبات الـ PKI تمكن مسخدمي الحواسيب من استخدام معلومات المفتاح العام بشهادة فك تشفير المفتاح العام (Public Key Certificate) الخاص بهم لتشفير رسائل بعضهم البعض بدون اتصال مسبق فيما بينهم لكنهم يثقون ببعضهم.
Passwordless authentication methods typically rely on public-key cryptography infrastructure where the public key is provided during registration to the authenticating service (remote server, application or website) while the private key is kept on a user’s device (PC, smartphone or an external security token) and can be accessed only by providing a biometric signature or another ...
Key authentication. Key/Config-authentication is used to solve the problem of authenticating the keys of a person (say "person A") that some other person ("person B") is talking to or trying to talk to. In other words, it is the process of assuring that the key of "person A", held by "person B", does in fact belong to "person A" and vice versa.
v. t. e. The Secure Shell Protocol ( SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. [1] Its most notable applications are remote login and command-line execution. SSH was designed for Unix-like operating systems as a replacement for Telnet and unsecured remote Unix shell protocols ...
