RFC 5990 Use of RSA - KEM in CMS September 2010
نویسنده
چکیده
The RSA-KEM Key Transport Algorithm is a one-pass (store-and-forward) mechanism for transporting keying data to a recipient using the recipient’s RSA public key. ("KEM" stands for "key encapsulation mechanism".) This document specifies the conventions for using the RSA-KEM Key Transport Algorithm with the Cryptographic Message Syntax (CMS). The ASN.1 syntax is aligned with an expected forthcoming change to American National Standard (ANS) X9.44.

Use of the RSA - KEM Key Transport Algorithm
The RSA-KEM Key Transport Algorithm is a one-pass (store-and-forward) mechanism for transporting keying data to a recipient using the recipient’s RSA public key. ("KEM" stands for "key encapsulation mechanism".) This document specifies the conventions for using the RSA-KEM Key Transport Algorithm with the Cryptographic Message Syntax (CMS). The ASN.1 syntax is aligned with an expected forthcomi...
متن کاملSecuring RSA-KEM via the AES
RSA-KEM is a popular key encapsulation mechanism that combines the RSA trapdoor permutation with a key derivation function (KDF). Often the details of the KDF are viewed as orthogonal to the RSA-KEM construction and the RSA-KEM proof of security models the KDF as a random oracle. In this paper we present an AES-based KDF that has been explicitly designed so that we can appeal to currently held ...
متن کاملRSA hybrid encryption schemes
This document compares the two published RSA-based hybrid encryption schemes having linear reduction in their security proof: RSA-KEM with DEM1 and RSA-REACT. While the performance of RSA-REACT is worse than the performance of RSA-KEM+DEM1, a complete proof of its security has already been published. This is indeed an advantage, because we show that the security result for RSAKEM+DEM1 has a sma...
متن کاملCryptographic Message Syntax (CMS) Content Constraints Extension
This document specifies the syntax and semantics for the Cryptographic Message Syntax (CMS) content constraints extension. This extension is used to determine whether a public key is appropriate to use in the processing of a protected content. In particular, the CMS content constraints extension is one part of the authorization decision; it is used when validating a digital signature on a CMS S...
متن کاملComplementary medicine use among Iranian breast cancer
A cross-sectional study was conducted to evaluate use of complementary medicine by cancer patients, in two comprehensive clinics, in Tehran, Iran. This paper reports the results for breast cancer patients. Design: A specially designed questionnaire was completed for 177 breast cancer patients after informed consent was obtained. The Mean age of the participants was 47.61 years (SD= + 15.1) rang...
