摘要：A system and method are provided for enabling a symmetric key to be derived,the method comprising: obtaining a plurality of key parts, wherein the plurality of keyparts when combined equal the symmetric key; encrypting a first of the key parts using afirst cryptographic algorithm to generate a first encrypted value; encrypting one or moreremaining key parts of the plurality of key parts using respective cryptographic

algorithms to generate one or more additional encrypted values, wherein each key partencrypted is encrypted using a different cryptographic algorithm; and providing the firstencrypted value and the one or more additional encrypted values to an other entity toenable the other entity to derive the symmetric key.
