The primary purpose of encryption (or <i>encipherment<\/i>) techniques is to protect the confidentiality of stored or transmitted data. An encryption algorithm is applied to data (often called <i>plaintext<\/i> or <i>cleartext<\/i>) to yield encrypted data (or <i>ciphertext<\/i>); this process is known as <i>encryption<\/i>. The encryption algorithm should be designed so that the ciphertext yields no information about the plaintext except, perhaps, its length. Associated with every encryption algorithm is a corresponding <i>decryption algorithm<\/i>, which transforms ciphertext back into its original plaintext.<\/p>\n<p>An asymmetric, i.e. public-key, encryption scheme allows a sender to use a recipient&#039;s public key to transmit an encryption of a message to the receiver, who can use his secret key to decrypt the given ciphertext, thereby obtaining the original message. <\/p>\n<p>Such a scheme should be secure in the sense that no information about the message should be leaked to a (resource-bounded) attacker, even if that attacker mounts a so-called &#039;chosen ciphertext&#039; attack, in which he may obtain decryptions of other ciphertexts. This is the strongest type of attack that has been proposed for a public-key encryption scheme. <\/p>\n<p>ISO\/IEC 18033-2:2006 specifies the functional interface of such a scheme, and in addition specifies a number of particular schemes that appear to be secure against chosen ciphertext attack. The different schemes offer different trade-offs between security properties and efficiency.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Information technology \u2014 Security techniques \u2014 Encryption algorithms \u2014 Part 2: Asymmetric ciphers<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/iso\/\"><b>ISO<\/b><\/a><\/td>\n<td>2006-05<\/td>\n<td>132<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":633687,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[656,2634],"product_tag":[],"class_list":{"0":"post-633673","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-35-030","7":"product_cat-iso","9":"first","10":"instock","11":"sold-individually","12":"shipping-taxable","13":"purchasable","14":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/633673","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/633687"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=633673"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=633673"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=633673"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
